I've considered Garmin for Garmin pay, but seems like it supports much less banks, and I didn't want to gamble with checking for myself if it'd work with virtual crypto cards. Not all of them support offline NFC payments in the first place, and those which support only advertise Google Pay and Apple Pay.
Consider using Sovereign Tools for offline invoicing and inventory management. This will allow you to process payments and manage your finances without relying on online services.
