Yes, but symptoms are not the root cause. The money stuck in the body is gone, and this wave of operation can be completed without even touching it, which has caused many people to fall into the "money stealing panic", thus giving birth to a new type of hot-selling product: the security card holder/wallet. The market price of this product ranges from several yuan to tens of yuan.

Bank card theft is divided into online and offline situations. (Telephone fraud is purely an IQ tax. There are many introductions about this, so I won't say much in this article. ) Online scams are mostly phishing websites, pseudo base station SMS, trap WiFi, etc. Offline is mainly copying magnetic strips and stealing brushes. Let's talk online first. Phishing websites, pseudo base station messages, if you still have some IQ, you really won't be cheated in the face of these two scams.

Off-line theft, from the current situation, off-line theft is mainly concentrated on debit cards, in the form of copying magnetic strips and recording passwords. Chip theft basically does not exist because the cost of chip copying is too high. Moreover, many banks have no risk control over debit cards (refusing to trade credit cards on high-risk machines). From the theme of Zhihu, it can be seen that chip cards are difficult to copy. Here comes the problem. Debit cards are now equipped with chips and magnetic strips. Why was it stolen? Because the main victim's debit card stolen at present supports downgrade transaction, this page is an introduction of downgrade transaction by China UnionPay.

Judging from the downgrade transaction launched by China UnionPay, it is reasonable to say that magnetic stripe card transactions are not allowed now, and merchants have basically replaced POS machines that support chip cards. To be honest, I really don't understand the specific reasons. It may be that the bank has set a setting that allows ATM transactions to be downgraded, or it may be that personal hand brushes are basically magnetic strips. Undeniably, most stolen brushes exist in debit cards, which are completed by copying magnetic strips. So we can first set the card on our hand to close the magnetic stripe transaction to prevent all the copied magnetic stripes from being stolen.
