Problems solved by technology

[0003] Taking mobile phones as an example, there are two shortcomings in the power supply mode of mobile phones: one is that when the mobile phone is in the off state, it cannot provide working power to the radio frequency SIM card to complete the payment or credit card application; the other is that the radio frequency SIM card increases the Components also increase the demand for working current. Some mobile phones cannot provide the current that meets the stable operation of the RF SIM card in the standby state, resulting in the mobile phone being incompatible with the RF SIM card.

The smart card includes a smart card body module and a micro battery, and the micro battery is used for powering the smart card. The memory card provided by the invention can provide sufficient power supply to the memory card or smart card with extended functions.

Description

technical field [0001] The invention relates to the communication field, in particular to a memory card. Background technique [0002] With the development of mobile communication technologies, radio frequency memory cards (such as radio frequency SD cards) or radio frequency smart cards (such as radio frequency SIM cards) with extended functions such as radio frequency communication have been widely used. The addition of these extended functions requires a larger power supply. For example, the value-added applications of radio frequency SIM cards mainly include electronic wallets based on mobile terminals (such as mobile phones), access control, bus rides, VIP cards, etc. The realization of these functions depends on the increase of components in the radio frequency SIM card, and the application of these new functions cannot be separated from the power supply of the mobile terminal. [0003] Taking mobile phones as an example, there are two shortcomings in the power suppl...
