What does it mean to swipe the pre authorization to show invalid merchants

There may be one of the following reasons why the POS machine shows an invalid merchant:

1. The POS machine needs to communicate with UnionPay when swiping the card, it may be that the UnionPay backend host has not established the parameters of the POS machine, and the merchant's information does not exist in the UnionPay backend.

2. The key of the POS machine is lost.

3. The merchant has changed the flow card in the machine by himself, because the POS is the default lock of the traffic card that successfully signed in for the first time, if you need to replace the traffic card in the future, you must fill in the traffic card change application form (special merchant information change form), otherwise it will show "invalid merchant".

4. The POS machine merchant operated in violation of regulations and was shut down by the POS machine platform.

Credit card pre-authorization is equivalent to paying a deposit for consumption, but it is more convenient than paying a deposit, and the cardholder does not have to really take out the money. Compared to cash and debit cards, the advantages are obvious.

Take hotels, for example. When the cardholder checks in, the card is pre-authorized at the front desk of the hotel, and only a certain overdraft limit on the cardholder card will be frozen, and the actual consumption deduction will be deducted and settled when the cardholder leaves the hotel. Credit card pre-authorization transactions are not available for all POS, and UnionPay only allows a few industries such as hotels, car and boat rentals, to enable this function.

Pre-authorized BAI business refers to the special merchant obtaining the cardholder from the card issuer within 30 days

In the amount not exceeding the pre-authorized DAO must be specialized.

Credit card pre-authorization means that the merchant freezes a part of the funds before the cardholder spends money, and the cardholder signs after the consumption is completed, and the merchant can officially deduct the right to share the funds. For example, if you go to a hotel and tell the hotel that you want to stay for a few days, the hotel will freeze the cost of staying for these days from your credit card, and sign and confirm when you check out and leave the hotel, and the hotel will receive this part of the payment. This is done to ensure that the cardholder's credit card has enough money for current spending.

Pre-authorization refers to the behavior of the cardholder who consumes in a guesthouse, hotel or rental company, and the consumption and settlement are not completed at the same time, and the special unit requests authorization from the card issuer in advance through POS.

The so-called "pre-authorization", in layman's terms, means that when the cardholder checks into the hotel, the hotel estimates the consumption amount according to the number of days of stay, according to the hotel's pre-payment deposit regulations, and requires the cardholder to swipe the credit card to do "pre-authorization", that is, to pay the deposit. The hotel cashier swiped away 1,200 yuan, in fact, the money is still on the cardholder's card, and it was not paid to the hotel, but the amount was frozen, and the POS list was blank, not the voucher for bank card deduction.

At the time of check-out, the hotel will destroy the original blank pre-authorization POS slip and re-check the bill according to the actual consumption of the cardholder. (Some banks call it "pre-authorization confirmation").

The hotel will require the cardholder to swipe the card and sign again, and the actual consumption amount will be deducted from the pre-authorized amount, and the remaining frozen funds will be released. At this time, the amount of the card is the real payment to the hotel.

The pre-authorization of 300 yuan is equivalent to temporarily freezing your account of 300 yuan, and when the pre-authorization is deducted, the 300 yuan will be unfrozen.

The concept of pre-authorization is the same as **: the customer buys something, first deposits the funds into UnionPay, and then transfers the funds to the merchant's account after confirmation.
