Is it safe to use mobile phone scanning code and credit card to pay at gas station?

It is best to use cash or credit card.

With the increasing application of Internet and wireless WIFI technology in people's lives, various mobile apps emerge in an endless stream, and mobile payment, WeChat transfer and other forms are also increasing. At the gas station, in addition to enjoying preferential consumption, the fast payment method of directly scanning the code after refueling is also welcomed by many citizens.

However, it is clearly pointed out in the "Safety Code for Gas Station Operation" that the signs of "No Fireworks" and "No Mobile Phone" should be selected at the entrance and exit of gas stations, around them and in the operating fire zone; When doing hot work in the workplace, use the signs of "No Flammable Articles", "No Fireworks" and "No Cell Phone".

Then, is it safe to use mobile phones to pay directly at gas stations, especially to scan QR codes directly on site?

In the process of making a phone call, the electromagnetic wave of the mobile phone is constantly emitted, and the process from dialing, connecting to hanging up is generally more than 30 seconds. The reference value of electromagnetic wave power generated in the state of mobile phone conversation after passing through the receiving coupling plate is about 6 microwatts.

Of course, if you don't answer the phone, the power of the mobile phone is about 6 microwatts. The functions of mobile phones, such as watching news online, chatting on WeChat, swiping Weibo and paying by mobile phone, are all "data services". Compared with the call service, the most important feature is "short call time".

Obviously, when using mobile phone to surf the Internet and pay by QR code, the generated electromagnetic wave power is greater than that of making a phone call, which means that the risk of fire hazards caused by using mobile phone to surf the Internet increases.

Under normal circumstances, the oil tank area, tanker, vent pipe and oil unloading port in the gas station operation area may discharge oil and gas, and using mobile phones in such dangerous areas may generate static electricity, which may easily cause danger.
