There are only numbers on the bank card, not letters. The fundamental reason why the number 6 is in the form of the lowercase letter b is to facilitate identification and copying and reduce errors.

Credit cards have a way of pressing transactions, which is to use the protruding information on the front of the credit card to press information on the pressure-sensitive document. Printed fonts 6 and 9 are easily confused with 8 due to handwriting defects when placing orders, so it is safer to use special fonts.

The process of manual order pressing for credit card transactions:

Manual order pressing is usually used when there is no POS machine or the Internet is not available.

The order pressing operation must have a pressure-sensitive copy of the "direct purchase order" (at least two copies) and a telephone number. The inspection work before pressing the order is the same as that of the POS machine. The operator then prints the card number, name, etc. raised on the credit card onto the purchase form using a credit card pressing device, and writes the amount, date and other information, and then calls the acquiring bank's authorization hotline to report the card information and apply for authorization. , and write the authorization code obtained on the purchase form, and then the cardholder signs it after confirming it is correct.

After checking the signature, the operator hands the credit card and purchase order copy to the cardholder. At this point, the manual order pressing process is completed. Authorization calls are usually made immediately. In some areas with poor communication or good credit ethics, merchants may encounter situations where the merchant will deliver the goods to complete the transaction after pressing the customer's signature. The authorization will be completed in the future, but the merchant is at risk of encountering credit card fraud (if a customer pays with an invalid card, it will not be discovered immediately without applying for an authorization code immediately).

Because of this pressure transaction, the numbers on the credit card need to use special fonts.
