Let's look at another similar case provided by the police. Ms. Zhao, a citizen of Lu 'an, recently reported to the local police that her bank card was stolen and spent more than 2,000 yuan, and she did not receive any reminder of the bank's balance change. What is embarrassing is that the bank card was around at that time.

Under the careful inquiry of the police, it turned out that just a few days ago, Ms. Zhao' s mobile phone had no signal for no reason, and she could not make a phone call or receive a text message. Because his mobile phone is dual-card dual standby, Zhao Nvshi didn't care about this problem when the other card was still available. The day when the mobile phone card didn't signal was the same as the day when the bank card was stolen.

According to the investigation, the police suspected that someone had intentionally copied Zhao Nvshi's mobile phone card, which blocked the short message of bank balance change. Judging from the information released by the police, the modus operandi of this new type of fraud case can be simply summarized as four words, namely "changing cards and intercepting codes".

How does "changing cards and intercepting codes" work?

First of all, the so-called "replacement card" means that the criminal suspect uses the forged victim ID card to reissue the mobile phone card bound to the bank card at the communication operation outlet, thus "scrapping" the owner's mobile phone.

The second step is "code interception"; The so-called "code interception" means that after the criminal suspect successfully replenishes the card, when stealing the victim's bank card, he can transfer the money by using the dynamic verification code information such as the intercepted short message without the bank card password or the online banking payment password.

Be careful when the cell phone doesn't signal for a long time.

With the rapid development of online finance, more and more people move their banking business to the Internet and mobile phones. At the same time, privacy information leakage, phishing, Trojan horse virus, hacker attacks, online fraud and other security risks have followed.

In the face of various fraudulent means, the police reminded that in addition to the fault factors, if the mobile phone has no signal or cannot be used for a long time, it is necessary to be alert to whether the criminals have reissued the mobile phone card; If you change your mobile phone number, you must unbind the relevant bank card in time.

Do the following things to make your money safer.

1. Protect the "four big pieces" of personal information: ID card, bank card number, mobile phone number, password and other important information.

2. Don't give your mobile phone wallet carrier (such as SIM card, SD card, mobile phone, etc.). ) for others to use.

3. Download financial service application software through formal and secure channels, and carefully connect unknown network hotspots or click website links.

4. Try to avoid using the same password for a long time. It is recommended to modify all kinds of passwords in financial business regularly, once every two to three months.

5. In terms of password setting, the password of mobile banking should be different from QQ, WeChat, Weibo, e-mail, recruitment websites, forums, post bars and online games.

Apple mobile phone charging display

Reason 1: the lightning interface IC of the data line is not working normally, and the data line is damaged. Replace the data cable.

Reason 2: The Lightning interface IC of the data cable works normally, but a pair of codes between the IC and the mobile phone can't work normally. Maybe the golden finger of the lightning interface has been used for a long time and is dirty. Try cleaning it up.

Reason 3: the lightning interface of data line is soldered with PCBA (circuit board) and the data line is damaged. Replace the data cable.

Reason 4: There is a high probability that this problem will occur in the shanzhai data line. Usually, upgrading a new system may lead to such a prompt. Please replace the original data cable.

Let's look at the reasons why the error message for this attachment is not supported:

Reason 1: There is a prompt when the data cable is connected. This problem is generally poor contact. Solution: First check whether there is dirt on the gold finger of the data cable, then check whether there is dirt on the tail plug of the mobile phone (data selection socket), and clean it with cotton swab alcohol.

Reason 2: This prompt is usually caused by insufficient power when charging with USB in front of the computer case. Please plug it in the back of the case or change the charger to charge.

In addition to the above two problems, after the mobile phone is connected to the data line, there are still phenomena of ding-dong, ding-dong and no contact.
