Here is a "wireless loyalty card" that shoppers carry with them in the store on their key fob. Do I think it will fly? Not sure – because of the infrastructure needed to read and write special offers to these fobs throughout the stores. But, I think the idea is in the right direction Scansave (company I founded) is working on an alternate approach where your points/loyalty/credit card in your wallet has a special surface that prints, erases and reprints offers right onto your card. Imagine visiting Costco, Sam’s Club or BJ’s and when you take out your card, you show it like you do today, then you swipe it, and your card is imprinted with offers… JUST FOR YOU!
Scansave offers PVC loyalty card solutions with re-printable surface
