1, look at the cards:
When a customer provides a credit card, whether it is a fake card can be identified by the validity period of the card and the beginning of the card number.
In terms of validity, the general format is "MM/YY", that is, "month/year". Just look for the number with "/"on the front of the card. If the format is wrong or the validity period has passed, it must be a fake card. As for the card number, domestic POS machines can use UnionPay cards starting with 62. If you encounter other numbers starting with 5, 3 and 4, it is confirmed as a fake card.
2. Look at the signature column:
If the cardholder's signature is required after swiping the card, be sure to check whether the signature behind the signature column is consistent with the signature of the shopping list. If there is no signature in the signature column, or the reserved signature is unclear, altered or inconsistent with the signature of the shopping list, be sure to call the issuing bank for confirmation. If the card transaction is false, you can apply to the issuing bank for cancellation.
3. Check the pos receipt after swiping the card.
After swiping the card, check the information on the credit card with the information on the POS ticket, mainly to see whether the card numbers such as the issuing bank and credit card number are consistent. For example, if the issuing bank on the credit card is ICBC, but the credit card opening bank on the POS machine shows China Merchants Bank, or the credit card number does not match the card number on the POS machine, then there is no doubt that a fake card has been encountered.
The above is the introduction of "How to prevent counterfeit credit cards from being stolen", and I hope it will help everyone. In short, the key to prevent counterfeit credit cards from being stolen is to identify counterfeit cards at the first time, otherwise, once counterfeit cards are used for transactions, businesses will take the fall for criminals.
