How to close SMS in pos machine?

Personal information in the POS machine will not be leaked, and there is no need to cancel it. When it is no longer used, just throw away the POS machine.

If you have to log out, you can try the following methods:

1. Communicate with the salesperson who issued the pos machine and explain the reason, so as to cancel the operation;

2. Communicate with the bank to which the machine belongs and apply for canceling the operation of the pos machine;

3. Call the customer service phone of the receiving bank, explain the number of the pos machine to be cancelled, and ask for cancellation of the pos machine.

It should be noted that the above method is only an attempt, and it cannot ensure the successful cancellation. In this case, you can try further:

1.POS stopped using for more than half a year;

2. Cancel the customer service through reasons of long-term non-use;

3. If the customer service says it can't be cancelled, you can force the cancellation by complaining about the tone of the payment company.

It should be noted that once you do this, it means that you have no fate with the POS machine of this payment company.

Because the general payment company will pull you into the long-term blacklist. Therefore, if you use this trick, you must think about it.

Matters needing attention in using personal POS machine to swipe cards:

First of all, a swipe failed. After swiping the card again, you must carefully check the consumption details of the credit card. If problems are found, they should get in touch with consumers and relevant banks in time to avoid financial losses.

The second is to check the correctness of the amount on the shopping receipt. When a consumer makes a transaction, according to the transaction requirements of the bank card, the cashier will ask the consumer to sign the transaction document.

It is worth noting that before signing, you should confirm and carefully check whether the amount and currency on the purchase order are consistent with the actual consumption situation, and then sign after confirmation.

Third, don't tear up the transaction documents when using the credit card reader. A transaction document is a transaction document. Therefore, the transaction documents must be properly kept, so that they can not only be kept for future verification, but also be prevented from being forged.

Fourthly, when using a credit card reader, the card swiping operation is different from that of a savings card. Credit cards not only need no principal, but also do not need to enter a password when using many credit cards. The cashier only needs to check the user's signature.

Of course, this convenience also brings some unsafe factors to credit cards. Once a consumer's credit card is lost or forgotten, it is likely to be stolen. Therefore, everyone should be extra careful when saving credit cards, and it is best to protect them as cash.
