There has been two forms of this. Firstly with Apple's Passkit (runs both Apple Pay and Wallet) have been until recent two separate and walled off gardens. As I stated in 2016, "Disney could implement this, the same way they could if they used an NFC gift card, but I understand why Apple locks off the NFC for the Apple Wallet applications. The Walgreens Loyalty cards are now NFC for Android aswell, and while that still uses NFC, it's not implemented on iOS as an NFC card but as a barcode scanned card." Apple's Passkit outside of the NFC features, uses Aztec, PDF417, and QR 2D barcodes and Code 128 1D barcodes, which is how there has been boarding pass applications for quite some time with Airlines. However the NFC Functionality was not opened from the WWDC in 2019, with expanded support with to their Core NFC Functionality in 2020. Before that, it was not possible. I wouldn't be surprised if Disney would be going to the approach of the Car Keys functionality that was announced at WWDC 2020 which I am sure was also a limiting factor as if you want to develop an app that uses NFC and the Passkit framework, you must request an NFC certificate from Apple.
