I have a bit of a unique application. I'm trying to create fancy ID cards for local membership.
It's a cocktail club, and they're doing some cool things with the front of house and service structuring. All that to say, they want to use some nice brass magstripe cards for members IDs, but they'd like to further integrate them into their POS, which is currently Square for Restaurants.
I've talked to them about RFID, and about magstripes, but I'm further not entirely familiar myself with what the POS system looks at from a credit card stripe, which stripe the data lives on, how it's encoded past the reader, etc.
I've got a reader/encoder that I can use to read data, but I'm not seeing consistency between the selection of cards I have in front of me. I have some work to do on the interpreting side, I suppose. Does anyone have experience encoding data on a magstripe specifically for use by a POS system? I'm only trying to create a card that mimics the functionality of a credit card for ID purposes, so not for payment, and I'm not trying to take part of the credit card magstripe data from another real credit card to then repurpose on a created ID card for ID. These cards are totally separate from real credit cards, but use the magstripe out of convenience.
