Biometric Germs

The cast member sitting behind the glass window slid a brand new Annual Pass through the window's opening. A pass with my name on it! I held it up, to behold in all its glory, as the sun shimmered from behind it. The pass had that reasurring-familiar-concave bend to it, indicating that it had just come out of the warmth of the printer. Next stop, the turnstiles.

It was a rather crowded day, and the line between the turnstiles and myself seemed one mile long. It had been almost a year since my last visit, and needless to say I was quite anxious. I felt a warm tingling sensation as a train pulled up into the Main Street station. The sound of the engineer's bell coincided with the beating of my heart.

As the line moved forward, ever so slowly, I noticed a strange device between the turnstiles, directly above the pass-reader. It appeared to be a hollow, shiney metal box which I had never seen before. But I was still too far away to make out exactly what this contraption was.

I kept my eye on this mystical box, and noticed a guest place part of their hand into the box, and then continue through the turnstile. The following guest did the same. Upon closer inspection of yet the next guest, I noticed her place two fingers into the box, pause, and then continue through. "Well, this is surely interesting," I thought to myself.

After what seemed like an hour, I was closer to the turnstiles. As I counted the number of people between the turnstile and myself, I noticed a young boy, about to enter, picking his nose. He did this ever so vigorously, as his parents were obviously not paying attention. It was the boy's turn to pass through the turnstile, and his father handed him his ticket to slide into the reader. "Isn't that cute," I thought ...until what happened next.

The young boy proceeded to place his fingers, which had only moments earlier occupied the depths of his nostrils, into this silver box. I was quite repulsed by this sight, and suddenly became preoccupied with this silver box's function. Was this apperatus for cast members? Was it for resort hotel guests? Questions raced through my head.

It was finally the moment of truth. My turn had arrived. It was time to slide my virgin pass into the reader. I did so with pride, as though I had done it one hundred times before. I continued to step forward, only to stumble into a locked turnstile. "What is this, a faulty pass?" I asked myself. The cast member, who had been watching the adjacent turnstile, quickly noticed my dilema and turned to help.

He told me to place my two fingers into the "box." I looked at him with a puzzled expression, and replied, "Do what?" He repeated, "You have to place your fingers into the box first." I asked, referring to the box, "What is that?" Unfortunately, the guest relations cast member behind the glass window failed to inform me of this new requirement. The cast member at the turnstile, who appeared frustrated at this point, answered, "It's a biometric scanner and we need to scan your fingers before you can enter the park." The image of the young boy, who had placed his exploring fingers into that box moments ago immediately flashed into mind. I replied, "You've got to be kidding me."

The cast member, who many would qualify as "angry" at this point told me that I needed to do so, should I wish to enter the park. The guests waiting behind me became rather impatient as well. I replied to the cast member, "Do you know how many germs are in there?" This seemed like a reasonable question, but unfortunately it seemed to fall upon unreasonable ears. At this point the guests behind me were not as impatient as they were curious as to what was going on.

The cast member, obviously attempting to hold down his tone, said, "Sir, you have to either place your fingers into the scanner or I'll have to ask you to please step aside." As I stared down at that horrific box, a statistic immediatly came to mind; that 33% of people do not wash their hands after using the restroom (Virginia Department of Health.)

I realized that I had been holding up the line, and that it was time to do or die. So, I reluctantly placed my fingers into the scanner, waited for what seemed like eternity, and proceeded through the turnstile. The cast member, shaking his head as I passed by.

As I immediately began heading to the nearest restroom, I asked myself, "How could Walt Disney World do this?" Maybe the new catchphrase for WDW should be, "Did somebody say, hepatitis?"

Thoughts of hepatitis A, salmonellosis, and shigellosis raced through my head. I wondered which, if not all, I had just been exposed to. And to make matters worse, the restroom soap dispensers all seemed to be out of that "pink-sand" soap, which I am sure is of the highest medical-sterilizing quality.

I have since thanked the Walt Disney World company for placing the burden upon me of bringing a latex glove alongside my annual pass each time I visit a park, not to mention my own container of hand sanitizer.

Oh come on you dont seriously think you are at risk here...

You surely are not at any more risk with the finger scanner, than you are touching a door handle, holding the over-shoulder restraint at RnR, using headphones at Innoventions, holidng the rail on Splash Mountain.... the list is endless.

The scanner surfaces are regularly cleaned, and I imagine are used far less than some of the items I mentioned above.

I wouldnt suggest gloves! Will for sure interfere with the operation of the biometric authentication!!!

The pink sand soap was removed furing the anthrax situation.


The Biometrics have been around at WDW for a long time, since 1996. Here is some info on it....

The Automated Ticketing System (ATS), first launched in January 1996, makes ticketing easier for guests. The credit card-sized tickets replaced the dozens of admission passes in use since Walt Disney World Resort opened in 1971.

ATS tickets feature Disney characters and scenes that reflect a variety of Disney themes.

How it works: a guest purchases a one-day or multi-day admission. That information is automatically encoded on the back of the ticket. The ticket-holder then feeds the pass into an electronic turnstile. Turnstiles "read" the magnetic stripe and "validate" each admission. Multi-day guests simply re-use the same ticket for each day of their visit.

Annual and seasonal Walt Disney World passholders are getting a hands-on look at some of the most user-friendly technology available -- biometric hand-recognition devices.

After presenting a valid Disney passport, guests insert their index and middle fingers, palm down, into a simple stainless steel box. The device photographs the guest's fingers, calculates a formula that measures the dimensions and proportions of the two fingers and determines whether they belong to the ticket holder.

Guests staying at Walt Disney World resorts have their ticketing options encoded on the back of a Resort ID card which is used to charge food and merchandise purchases.

ATS ticketing is in use throughout Walt Disney World Resort. Guests who return with the old-style tickets can exchange them for a new ATS ticket at any ticket booth or Guest Relations location.

As I posted elsewhere, you can (politely) ask for an exemption from the scanner! My son has had, and will continue to have, surgeries on his hands which will change their configurations. After a brief explanation, he has always been exempted. I am starting to have arthritic changes in my fingers, and also have difficulty "matching" my previous scans because of this. I will request an exmption after my next renewal...I don't know if they will let me or not...I'll have to see.

And I agree, you are at risk if you touch anything! Perhaps you could bring a packet of hand wipes with you and swab the scanner? I've found that frequent hand washing while in the parks is a given!

I forgot to add.....

Disney are way ahead on this one....you will soon (within next 5 years) start to see biometric authentication systems appearing at point-of-sale everywhere. They will become the standard for authenticating credit purchases, ATM transactions etc...

There are quite a few types in devlopment.... Retina Scans, Finger Print Scans, Hand Geometry (as used at WDW), and Signature Dynamics (the process of determing an individuals identity based on characteristics of HOW they write, not what they write). Some of these are more intrusive than others.... and out of them all, I can say WDW have them most user-friendly - the others are far more traumatic to get thru!

OK i have finished my mini-lecture now LOL... Biometrical Signature Dynamics was my final year software development project at University - so its a pet subject for me!

Yes you would probably experience problems....
You first submit several sample signatures... the system then measures many parameters.... such as Pen Pressure, vertical velocity, horizontal velocity, acceleration on upstrokes, number of pen down points, time of pen being in contact with surface, total time take to write signature.... there are 100s of paramaters that describe your writing style.

The key to dynamics is that it is impossible for someone else to forge your signature even if they can see it and have it to copy. The system is about determining HOW you write your signature, and not how it actually looks.

An exmaple would be if you take the letter "S". Some people would start from the bottom, some would start from the top... even though the letter looks the same when written both ways, it is produced in 2 totally different ways. If you then consider how the same theory explans to an entire signature, with 100s of parameters being measured, you can see how it becomes highly accurate.

I believe signature dynamics will suffer from a too high false-rejection rate to be used on a mass scale. Fingerprint readers like at WDW have a lower false rejection rate due to the fact that hand parameters dont change like signatures.

Thanks for the info Steve!! You truly ARE the man!!:sohappy:

As far as germs in Disney Worlds Biometric Scanners, I agree with Steve that they don't pose anymore threat than a doorknob, or a handrail.

As I go thru the queue areas with handrails, like Space Mountain and Spaceship Earth, I think aout how many grubby little hands have touched these rail. As I wind through the wooden rail queue areas at Splash mountain and Big Thunder Mountain railroad I remember that wood actually absorbs germs and keeps them longer than metal.:lookaroun

The last time I rode Splash mountain, when I got off that ride I was discusted because my hands smelled like FEET from holding onto the bar on the little boats.

But I'm not mad at Disney for that. Every time I open a door or hold a handrail on an escalator I take a change on picking up germs.

Perhaps I'm a little paranoid. I think from now on I'm going to try not to think about these germs and enjoy myself more.

Until then I'll just keep carrying my little plastic bottle of PURELL Instant Hand Sanitizer around with me. It kills 99.9% of the germs
Hmmm...I wonder...I let my kids used my computer some times..maybe I better keep a bottle of that stuff on my DESK. :( :animwink:

Steve, since you seem to be pretty much an expert on this, perhaps you would know the answer. Does the swelling in my joints affect the reading? I seem to have a hard time most of the time, but not always. Would swollen joints affect the reading...I just assumed that was the problem, but I might be mistaken. Also, there is no question that my son's hand parameters change after each surgery, so I will continue to request an exemption. (also, he's a little uncomfortable having strangers look at his hands, as the CM would have to do if the scanner isn't working for him.)

Also, since my son changes his dominant hand constantly, I would think the handwriting identification would be problematical.

Just curious, would the retinal ID be affected by cataracts?

This is making the ID bracelets sound better and better; maybe they're not such an imposition after all! Or maybe Disney could just change their whole ticket policy! I mean, if I pay for the damn thing, shouldn't I have the right to do what I please with it? Obviously, this would create a problem if people were lending their annual/seasonal passes, but I don't understand the restrictions on daily/park hopper tickets. (I UNDERSTAND the financial aspect, just not the PR aspect)

OK with the swelling issue... it is likely that this would have some impact on the performance of the system. Each biometric system has a set of parameters that it measures, and for obvious reasons this list is not disclosed. But if we assume that the WDW system is measuring at least lenghts, widths and separations of 2 fingers, a change in the position of those fingers would cause problems.

During the time I developed this kind of system, my testing often showed some people were just not compatiible with certain types of biometric tests, and it is for this reason that they are not in widespread use right now. The WDW system however, is pretty tolerant in terms of variance. Systems are usually tunable to allow varying degrees of what the system considers to be a match.

Specifically talking about the WDW system, I can recommed a few tips on getting through the system with a higher degree of success. You want to make sure you 2 fingers are pushed far forwards, right up to the rubber stop that fits between your 2 fingers. You then want to squeeze the centre pole between your 2 fingers pretty hard. I noticed doing this changed my success rate from about 75% to 100% - I havnt been rejected now in 2 years since using that technique (LOL! thats jinxed it for me now! next trip I wont be able to get in at all! LOL :) )

Also be aware that the system is basing all decisions on a comparison to the details it derived on your FIRST trip using that ticket. So it may be worth getting guest relations to issue you a new pass, and reinitialise your parameters using the entry technique above. If you then follow that system through again on normal entry, you should be fine.

I can see the problem with your son, and it is a real problem of this type of system. It really does penalise anyone who has any kind of injury or hand problem. Changing his dominant hand would be sure to cause problems in any system, especially the handwriting system.

Retina scans have similar problems, in that contact lenses, and eye problems can cause issues. It is also fairly intrusive, and not easy to setup for a mass entry system like at WDW. I know I wouldnt be comfortable doing it.

The system to fix all of these problems is the next wave of biometrics, which look at the chemical makeup of an individual. This checks various levels of certain chemicals in your skin to determine if you are you. This will work on everyone, and will have no issues with physical makeup of hands, eyes etc... and it is done without any blood extration or needles - it actually looks at things like salt levels in sweat etc - which are present on skin at all times.


In the long run biometrics are the only way to go, and they will change everything. If we can determine with certainity that someone is who they say they are, there will be no further need for tickets, paper money, credit cards, passports or anything. All you will need for entry to somewhere is your own body, which you cannot leave behind or lend to someone else!!! That is basically what it is all about. If WDW could be 100% confident of biometric success right now, your physical AP pass would not exist, your body would be your ticket! :)

I agree the splash mountain smell is horrible! I dont think its the rails in the boats though. I heard that it was the seat pads them selves. Disney is supposedly supposed to replace them with a type that wont absorb the water or get moldy.

As far as the whole germ thing on rails, scanners etc.. Why worry? We touch thousands if not millions of diferent surfaces evry day and dont even think about it. I mean you cant go through life worrying about getting hepatitus!

I mean if I were to see someone pick there nose and then touch something...I would be appauled to. But ppl put there hands in all kinds of disgusting places and touch stuff that you touch everyday...if your constantly thinking or worrying about things like that you're not going to have much of a good time no matter where you are...things like that can escalate to severe psychological problems too. I'm sure you've seen the programs on Discovery chanel or TLC. :)

Timekeeper, at the risk of being offensive, get over it. I will agree that this particular case is both obvious and offensive, but do you realize that absolutely everything you touch is contaminated to one degree or another. Most germs and viruses have a relatively short life outside of the host. But, if you're going to obscess about it, you don't know when anything you touch in the park, or anywhere else in the world, was last exposed to an infectious agent. The non-hand washing statistic applies to everything in the real world including the the door of the bathroom that you touch after you wash your hands. If it bothers you that much then I suggest that you wear gloves, preferably non-latex to avoid protein induced allergies, all day, every day. A mask would also be a good idea since you never know when someone is going to sneeze and aerosolize a few million virus particles. My background includes both undergraduate and graduate coursework in microbiology and bacteriology so I am well aware of the dangers that microbes and viruses can cause. Your fears, in my opinion, border on the irrational outside of this one particular case. Personally, I would simply go to a different line in a case like this.

Ya know I could have said that too...just didnt want to get too technical. ;)

Yeah, I agree with other people, you're just freaking out about nothing...if you want to be so germ free, live in a bubble, and clean the bubble all the time too. (Hopefully no one takes offence to that...?)

Thank you all for sharing your opinions, suggestions, and concerns. While I agree that just about "everything" in a public area is frequently touched and contains germs, no one "forces" you to place your hands on a rail, and there are plenty of people who use a paper towel to open bathroom doors when leaving, etc. (In other words, the WDW technique may be viewed by some as rather invasive.)

I was simply pointing out something using the elements of exaggeration and fiction. Sorry to burst any bubbles, but the particular incident I referred to did not actually take place as detailed. (It was, however, based on a few of my own observations upon my numerous park visitations.) No, I don't really have a problem with the scanners, and no, I don't bring gloves with me to the park. In fact, the post was originally geared towards one of a humorous tone, simlar to my other posts (see my reply to "short people have no reason to live") but I understand if that may have escaped some readers.

Now, on a more serious note, if these biometric scanners are so accurate, why aren't they in place at Pleasure Island? Although I am not aware of the actual statistics, it seems as though a large amount of guests there are annual passholders. So, instead of taking the time to check driver's license ID's at the turnstile, why not just install scanners? If a person was under 18, or over 21, that information would be stored on the pass (via their birthdate), and the scanner would inform the CM if they warrant a wristband or not. This would not only be more efficient, but also a more effective security measure (against fake IDs, etc.)

On a somewhat off-the-beaten-path note, I have managed to establish a rather impressive collection of unbroken/intact wristbands, of all available colors, used at P.I. Although bartenders are required to I.D. someone if they appear under 30 years of age, all you kiddies who don't want to drink - and just want to club-hop without your parent or legal guardian, just let me know.

When you purchase from me, you recieve an entire set of bands (one of each color), which are re-usable if you follow my instructions - which may be found within my pamphlet, "Caring for Your Wristbands." If you act right away, I will include this pamphlet free of charge. As a bonus, I will also include my pamphlet, "The Art of Pleasure Island Handstamps." This pamphlet displays crystal clear recreations of all P.I. handstamp designs used alongside the wristbands. This, of course, is for "educational purposes" only. Walt Disney World art is a staple of the company name, and it does 'not' end at the gallery walls. All WDW art, whether an original animation cell from Snow White or a park handstamp design, should be admired and appreciated.

My current work-in-progress: "Invisible Tattoos - The Art of Drawing Images Only Visible Under UltraViolet Lights - A Beginners Guide."

(Unfortunately, not everyone has an ultraviolet light, so if one choses to recreate the magic of WDW UV handstamp art on their own hand, they may be viewed under the UV lights provided to guests at the "same day re-entry" turnstiles, free of charge.)
