Battery pack for mobile communication terminal and NFC communication method using the same

摘要

A battery pack for a mobile communication terminal includes an NFC unit, a smart card unit and an antenna. The NFC unit communicates with a mobile communication terminal body and communicates with the outside via non-contact NFC. The smart card unit communicates with the NFC unit. The antenna is configured such that the NFC unit transmits/receives signals via non-contact NFC through the antenna. Accordingly, the characteristics of analog signals transmitted/received through the antenna are prevented from being changed despite the frequent attachment and detachment of battery packs.
