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.

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.
