Payment code is a payment method of WeChat online payment software. Consumers display their mobile phones when they check out, and merchants can use infrared barcode scanners to scan the one-dimensional barcodes displayed on users' mobile phones to initiate cashier. Wechat payment code can be used many times, but there is a time limit, usually one minute. After one minute, the WeChat QR code will be automatically updated.
Extended data:
If you have bought something paid by WeChat in a convenience store, you must know that the cashier will guide you to open the payment code, and she will directly use the code scanner to scan your green code for deduction. Generally, it consists of a barcode and a QR code, which is one more barcode than a receipt.
If you look at this QR code from the photo album yourself, you will get a series of numbers. In fact, the merchant reads your encrypted number with an ordinary scanning gun, and then transmits it to the server of the payment system provider together with the payable amount to complete the payment. And in fact, you also have this code when you use Alipay.
Only Alipay is better than WeChat in this detail. A prompt will pop up when taking screenshots, warning you not to send screenshots of payment QR codes to others. For security reasons, this code will be updated every minute, and once the payment code is scanned, it will automatically become invalid.
As long as this string of numbers is connected to Alipay or WeChat payment, the deduction can be read, and the payment code is within 1000 RMB, and there is no need to enter a password. Once someone with ulterior motives has obtained your payment code, you can sweep away your money by accessing Alipay or WeChat payment merchants.
It doesn't matter if it is stolen. You can immediately complain to WeChat or Alipay and provide evidence. WeChat or Alipay will freeze the money and punish the illegal merchants. However, this situation is still very low. After all, it is not easy to access WeChat and Alipay merchants, and both WeChat and Alipay have records of merchants, so it will be relatively convenient to collect money.
