我不明白这与编程有何关系,但无论如何。
SIM 卡确实为无线(“RF”)设备提供“ID”,但是,它不提供常见 RFID 定义下的 RFID 功能。 (SIM 卡不通过 RF 发送 ID)

I don't see how this is programming related, but anyway.
A SIM card does provide "ID" for a wireless ("RF") device, however, it does not provide RFID functionality under the common RFID definition. (A SIM card does not send an ID via RF)
