In my country we used to have a heavily standardized type of money transfer card. It'd be used both for regular wire transfers in a "fixed payer, flexible payee" form where you'd get a booklet of them to fill out later, and "flexible payer, fixed payee" form you'd get mailed to your house to pay your bills, only having to write your account number on them, sign it, and mail it to your bank. They were designed to be machine-readable from the start for easy processing at the bank, and one of the ways they did this was by having all the fixed data encoded in a special font. When we started using smartphone banking apps, you'd just be able to scan a bill with your phone and it'd immediately read out all the data, fill in the missing stuff, and you'd only have to tap "confirm" to do the actual payment.
