China News Service, June 17th, according to the US "World Daily" report, recently, Ms. Feng, the owner of a supermarket in Chinatown, 8th Street, Oakland, California, said that some customers used fake credit cards to try shopping fraud, which she saw through. Ms. Feng reminded all Chinese merchants to be careful of similar frauds.
Ms. Feng said that recently, three women of African descent came to the supermarket to buy food, and the three were suspicious. She kept her eyes open and kept observing her actions. Three people bought more than 100 US dollars of goods, and successfully swiped credit card to pay. When they were about to leave, Ms. Feng felt wrong and asked the cashier to take a look at the shopping receipt and found that it read "Credit Forced". Immediately felt that the situation was wrong and quickly chased out and stopped three people. , Hope to check credit card information with them. Unexpectedly, these people did not return their heads, jumped on the roadside vehicle, and prepared to escape.
Ms. Feng was helpless and had to call Mr. Shang together, sitting on the front of the car that had not yet started, trying to stop them from running away. "There is no way to make this decision, because the police must be too late. They know they have problems and will run faster," Ms. Feng said.
After a stalemate, the three dropped a few bags of food from the car and drove away. Ms. Feng said that the three-seater car used temporary license plates and was ready to drive off after being drunk, obviously guilty. "I don’t usually go to check the consumer’s shopping ticket. This time I’ve got a look. It’s completely a problem with the three scammers. The average person is picking and picking. The eyes of the three of them are wrong and they keep looking at me. With the clerk, I decided to check the receipt again."
Ms. Feng reminded Chinese merchants that similar credit card fraud methods are concealed and special care should be taken. Usually, the credit card will send a message to the bank after swiping the card. If the message cannot reach the bank headquarters, the credit card has a manual option to allow the cashier to force the transaction. In fact, there is a problem with the credit card. "In the past, there were more credit card frauds. Since the credit card was added with a new chip, the frauds have decreased. I don't know why similar scams have come back."
In a normal transaction, when someone swipes the card, the credit card machine sends encrypted information to the issuing bank. The bank checks the transaction amount, ensures that there is sufficient credit or funds in the account to allow the transaction, checks for any signs of fraudulent activity, and then returns the result of "yes" or "no" back.
Mandatory transactions are equivalent to bypassing part of the process of checking account balances. Once the credit card machine is connected back to the internal network or cloud network, the transaction will be uploaded and settled, and the merchant will not realize that the credit card failed, and will not receive the processing report until the end of the month.
