I’m afraid to use mine... because some stores may not have the reader.
Not because of the Devil.
The bank says if run backwards through the reader it will create a strange “latin sounding” invocation but just to ignore it.
If they don’t have the chip reader, you just swipe the card like previously.
I’ve probably done that in a dozen places, I haven’t seen a gas station yet that has the chip reader installed. WalMart and Meijer have the chip reader on their check lines.
