I have an EMV Bin-2 Test Card
One night while I was testing, the card suddenly wasn't recognized, but the last transaction was fine.
Device: Clover mini gen2
Touch: Fail.
Swipe: Fail. && Insert: Fail.
However, transactions where the card number is manually entered are normal.
Is this card broken, or is there something wrong with the machine, or is there some kind of restriction? I checked the documentation and found nothing. Can I get some help? Thank you all.
