We were in the same boat as many here. There was zero training for the chip card reader, one day the card reader made obnoxious noise and we just had to wing it. It's really not a big deal, like pretty much anything else you read the prompts and go with it.
One question I have that I didn't see in this thread, and sorry if I missed it, when you run a debit card with a chip in it it doesn't ask for a PIN and it never gives a cash back option. We have had the chip enabled for a few weeks now, does anyone have a way to offer cash back that they know of?
