Let’s first look at a similar case provided by the police. Ms. Zhao, a Lu'an citizen, recently reported to the local police that more than 2,000 yuan was stolen from her bank card and she did not receive any balance change reminders from the bank. The strange thing is that the bank card was with me at that time.

After careful questioning by the police, it turned out that just a few days ago, Ms. Zhao’s mobile phone had inexplicably lost signal, and she could not make calls or receive text messages. Because her mobile phone has dual-card dual standby, Ms. Zhao did not pay attention to this problem when the other card was still usable. The day when the mobile phone card lost signal was the same day when the bank card was stolen.

Based on the investigation, the police suspected that someone had deliberately copied Ms. Zhao’s mobile phone card and blocked the bank’s SMS reminders of balance changes. Judging from the information disclosed by the police, the criminal methods of this new type of fraud can be simply summarized in four words, namely "replenishing the card and intercepting the code."

First of all, the so-called "Card replacement" means that the criminal suspect uses the forged ID card of the victim to go to the communication operation network to reissue the card. The mobile phone card bound to the bank card "disabled" the owner's mobile phone.

The second step is to "code interception"; the so-called "code interception" means that after the criminal suspect successfully replaces the card, he will use the intercepted text messages, etc. when stealing or transferring the victim's bank card. Dynamic verification code information allows money to be transferred without bank card password or online banking payment password.
