what should I pay attention to in credit card pre-authorization?
first, pre-authorization occupies the credit limit
pre-authorization will occupy the credit card limit. In general, the pre-authorization limit cannot exceed the upper limit of the available credit limit on the card. Once the advance is confirmed, the corresponding funds in the card will also be frozen until the advance is cancelled or repaid after use.
since the credit card pre-authorization occupies the credit card limit, it is suggested that cardholders bring more cash or credit cards when the pre-authorization transaction amount is large, in order to prevent the limit from being insufficient.
second, how to unfreeze the pre-authorization limit?
after payment, the cardholder can ask the merchant to cancel it immediately, and the general pre-authorization amount can be restored immediately. If the cardholder fails to cancel in time, the bank will automatically cancel within 3-45 days and restore to the corresponding limit. In addition, you can also convert the pre-authorization into actual consumption for deduction. If you have pre-authorized 1 yuan and the actual consumption is only 8 yuan, the remaining 2 yuan will be automatically returned to the card.
Third, carefully check the signing record of POS machine
When pre-authorizing, carefully check the signing form printed by POS machine, which will clearly indicate the transaction type. If it is a pre-authorized transaction, indicate the transaction type in the type column. Otherwise, please negotiate with the merchant to modify the transaction type.
Prompt cardholders to activate the credit card SMS reminder function, so that they can grasp their own consumption in real time.
fourthly, there are subsequent risks if the pre-authorization of the credit card is not cancelled
In fact, it is best to cancel your pre-authorization of the credit card immediately after the transaction is completed, because after the transaction is cancelled or ended, if the cardholder fails to handle the pre-authorization within the time specified by the merchant, the merchant can cancel the pre-authorization or deduct the money, and the bank will not refuse to pay. That is, if you do not cancel the pre-authorization transaction in time, repeated deductions may occur.
Fifth, protect the credit card verification code and other card information
Stealing credit cards by using credit card pre-authorization often happens overseas, because overseas pre-authorization transactions do not need to enter a password, as long as the other party knows your credit card number, expiration date, verification code and other information, it can be stolen. Therefore, in order to prevent pre-authorization from being stolen, it is necessary to protect the credit card information.
