After a certain period of use, Tenpay will lock the card and sleep, and a special prompt will pop up. At this time, the user can try to charge one yuan into the card. If the recharge is successful, it will automatically unlock and close the special prompt.

This setting is to ensure the safety requirements of users in the offline card swiping environment such as buses and subways, and also to effectively control the number of blacklists and ensure that the transaction speed of passengers in offline scenes such as subways and buses is lower than the industry standard of 300 milliseconds.
