1, payment efficiency

In theory, face-brushing payment can save payment time and improve payment efficiency, but in practice, the efficiency of face-brushing payment is very low during the peak consumption period, and it may take more than three code scanning payments to complete a face-brushing payment. This is directly related to the high failure rate of face-brushing payment equipment, and many merchants' face-brushing payment equipment cannot be used because of the failure. In addition, the current error rate of face-brushing payment is also relatively high, which will also reduce the efficiency of face-brushing payment.

Step 2 pay concessions

Merchants and third-party organizations often offer preferential payment activities, such as coupons, but such coupons are generally only used for scanning code payment and do not support face-painting payment, which is the main reason why many people give up face-painting payment.

3. Pay the risk

The data paid by brushing face may be deciphered and stolen, which brings great hidden dangers to the security of account funds. Therefore, it is recommended that users who have already opened the face payment close the small secret payment in time.
