Link a bit, scan the QR code, the money is gone; the phone is lost, the money in the account is also stolen; received the number disguised as the official customer service of the bank ... Guizhou UnionPay recently released five security precautions for the Spring Festival and mobile payment .
Strategy 1: Don't believe the QR code information or red envelope link sent by a stranger. If you scan the QR code or click on an unrecognized red envelope link to open a website that requires you to install a new application, do not install it easily. When shopping online, if you encounter obvious strange behaviors by the counterparty, you should be vigilant and do not believe the counterparty's rhetoric.
Strategy 2: Keep the habit of setting the phone's power-on password. Install software that can be encrypted in the mobile phone, add a layer of password to the mobile payment software, so that even if someone cracks the power-on password, the payment software can still be password protected, and the login password and payment password must be set to different. If the login name of the mailbox and social networking sites (such as Weibo, Renren, Kaixin, etc.) and the payment account name are the same, ensure that the password is different. Don't save the password in your mobile phone, or set it as personal information that can be easily guessed, such as birthdays and license plates.
Strategy 3: Try to use digital certificates, Baoling, payment shields, mobile phone dynamic passwords and other necessary security products. "Electronic cipher failure", "U-shield upgrade" and other common fraud terms are used by criminals. If you receive a similar text message and cannot determine the authenticity, you should directly call the bank's official customer service phone and contact the bank staff for consultation, or It is to go to the counter of the bank branch. You must not log in to the online banking through the URL in the SMS.
Strategy 4: Do not put bank cards, ID cards and mobile phones in the same place when going out. If they are lost together, report it to the public security organ and the bank, because others can use the password retrieval function of the payment software to change the password, which is extremely dangerous. In case of theft of account funds, call 110 immediately. Once the mobile phone suddenly has no signal, after eliminating the signal problem and mobile phone failure, it is necessary to check whether the SIM card has been replaced by others, and transfer the balance in the payment platform.
Strategy 5: Scammers can disguise the signalling code as the bank's official customer service number through pseudo base station technology. Therefore, even if it is a similar text message sent by the bank's official customer service number, don't believe it. If you are really worried after receiving this type of text message, you must not directly call the contact number left in the text message. Instead, you must consult and verify through the bank's official customer service.
Magnetostrictive level sensor is composed of three parts: probe rod, circuit unit and float. To measure, the circuit unit generates pulses of current that travel down the magnetostrictive line and generate a circular magnetic field. A float is arranged outside the probe rod, and the float moves up and down along the probe rod with the change of liquid level. The float generates a magnetic field at the same time because it is fitted with a set of permanent magnets. When the current magnetic field meets the float magnetic field, it produces a "twisting" or "return" pulse. The time difference between the "return" pulse and the current pulse is converted into pulse signals to calculate the actual position of the float and measure the liquid level.
