At present, a Bluetooth communication module will be added to the smart card to realize information interaction and mass data transmission between wireless smart terminals such as smart phones. However, the power consumption of the Bluetooth communication module is a big burden on the battery in the smart card. Therefore, it is necessary to change the battery in the smart card to a rechargeable battery (such as a lithium battery) and provide users with a solution for charging the smart card.

In the prior art, the general charging scheme is: to charge the mobile phone or smart watch through the wireless charging stand, which requires taking out the object waiting to be charged on the mobile phone or smart watch, and placing it on a proprietary charging stand, the charging stand It is usually placed on the table and connected to a nearby power supply through a cable.

The above method requires the user to find a place with a power socket at any time to make the charging stand work, and also needs to take out the charging device from the body and put it on the charging stand to charge. This is often unacceptable to the charging process of the smart card, because the user usually puts the smart card (especially the financial IC card) in the wallet, and the wallet is put in the pocket, bag or backpack. Charging requires not only finding places with sockets everywhere (impractical for users who are often active outside), but also needs to take out the smart card frequently, which violates the normal usage habits of users carrying "card" items.
