GCs vs Bank Debit Card
I have a small grocery store which sells MOs for 38 cents (up to $500). I have successfully used my GCs for this. Recently they have asked 'is this a bank debit card?'. Well, yes it actually is a bank issued debit card. ;-)
Yesterday, I was again asked and then she added 'We have had problems with other cards'.
I always have my Citibank card in front of the GC just in case. I believe the cashier only sees the transaction as debit.
But can the back office tell if I used a GC as opposed to a card tied to a bank account?
What is the downside to the store for allowing GC's?
Thank you!
