Why can't the hotel invoice swipe machine swipe?

The credit card issuers in this place can't swipe their cards for the following reasons:

1. There may be something wrong with the card itself, such as expired, damaged or incorrect information.

2. The card reader is set incorrectly, which makes it impossible to recognize the card.

3. Network problems or communication failures prevent the card reader from communicating with the background system.

4. Problems with the bank card itself, such as being frozen by the bank or having a trading limit.
