POS machine is a widely used financial equipment, which is used to handle the transactions between merchants and customers. Traditional POS machines require customers to use credit cards or debit cards to complete transactions, and use signatures to confirm transactions. So, how to sign the POS card?

First of all, when a customer makes a transaction with a credit card or debit card, the POS will automatically ask the customer to sign it. Customers can use the screen on the POS machine or the pen in the signature area to complete the signature. After the signature is completed, POS will store the signature image in the transaction record and send it to the payment processing center for processing.
