What are the behaviors that are most likely to be blocked by credit cards?
1. Repeatedly swiping a credit card (debit card) on the same POS machine continuously has obvious cash withdrawal behavior. The same kind brushes off all the quotas on the same pos machine every month.
2. It is illogical to swipe a credit card (debit card), KTV in the morning, and buy electrical appliances in the middle of the night, and the credit card (debit card) is in a state of being empty for a long time.
