Hi, I own a Group Buying Scheme where my members receive discounts based on deals I negotiate with vendors eg supermarkets, utility companies, local businesses etc. I am not a programmer but I am looking to establish if I can have certain functionality with VISA debit & credit cards.
I would like to add a 'tag' or label to my members cards, with their written permission, so that vendors know which card payments to rebate the discount to. I am asking if such a tag system is available or could be created in this developer field to allow the vendor identify which payments come from our members and which do not.
