This system manages payments made using a mobile phone. An app on your phone generates a unique code, which holds a scrambled version of your payment card number. A store's checkout terminal reads this code and sends it to a central system, which then verifies the scrambled number with your bank to approve the purchase.
Why it matters: The claims specify a unique code encoding a tokenized primary account number. Since 2020, advancements in secure element technology and standardized tokenization protocols have potentially simplified the secure generation and verification of such codes, making implementation more robust.
