POS and credit card have to say those things

It has become a very common way to use a credit card to consume on a pos machine. Some things about credit cards and POS still need to be understood.

Benefits of using POS

First, for cardholders, the use of credit card payment is not only convenient to carry, but the points accumulated by credit card can also be redeemed. Therefore, the emergence of the POS machine can well meet the public's desire to “save the card easily and pay easily” when paying the transaction amount.

Second, the POS machine has the advantage of “cross-banking”, installing one machine and using multiple cards. It can reduce the transaction cost of the counter, reduce the user's queuing and reduce the risk of the customer being robbed and stolen, and break the limitation of time and space on consumption. It is very convenient for users, business and business operators.

Third, from the merchant's point of view, the cost of using a POS machine is much lower when comparing the business and cash transactions that entrust a third party agent to deposit cash. It can reduce the risk of collecting counterfeit banknotes and failing to cash the check.

Fourth, the POS function can greatly reduce the cash management risks of major enterprises and merchants, reduce the workload of manual collection, banknotes, change, prevent counterfeit banknotes, store cash, and use card payment to pay more health. More environmentally friendly.

Although the benefits of POS card swiping are many, we can't ignore some of the loopholes in the transaction.

First, using the POS machine will have a password to confirm the payment step, people with ulterior motives will peek at the credit card password when swiping the card, and then steal the brush.

Second, some merchants will use the negligence of the consumer to sign the confirmation after the card is swiped without checking the amount of the bill. Deliberately brush the amount, so that consumers are unconsciously in the middle.

Third, for cards that are signed to confirm consumption, some merchants repeatedly swipe their cards and overlap the bills to make you sign or counterfeit your signature illegally.

Fourth, there are also merchants that use special equipment to obtain credit card information and sell customer information to illegal elements for theft.

When you use a POS machine, you should not leave your own credit card. To enter the password is to pay attention to the protection, the signature is to carefully confirm whether the amount of the document is correct. In the event of a transaction error or cancellation of the transaction, the error document should be torn. The card should be recovered immediately after the card is completed. The transaction should be properly kept. It is convenient to check the risk to a minimum.
