What did the chip do? Did it track the shopping cart? Idea I had was a loyalty app for indie coffee shops. Spoke to a couple coffee shops But didn’t pursue any further
Discussion
the chip is just plastic which you use to unlock the cart,
normally you would use a euro coin for that
but often people forget their coins
but the chip they can put on their keychain!
Ah ok. Makes sense. Did you design and print them yourself?
yes i did the design and sold them on ebay first
now i got 4 printers running all the time
