Wireless chip module embedding NFC function, electronic price display terminal and method for operating wireless chip module embedding NFC function

摘要

The invention relates to a wireless chip module 100 embedding a Near Field Communication (NFC) function. According to an embodiment, the wireless chip module includes: a sleep mode block 10 which is always operated by receiving power, the sleep mode block receives an RF signal, and wakes up a tag block 30 when detecting an RF signal; the tag block wakes up from a sleep mode state according to a first internal wake-up signal of the sleep mode block, then determines whether the RF signal detected by the sleep mode block is an NFC signal or a network wake-up signal, the tag block performs NFC mode operation when the detected RF signal is the NFC signal; and a main block 50 that wakes up from a sleep mode state according to a second internal wake-up signal and performs communication according to the network wake-up signal when the detected RF signal is the network wake-up signal. Independent claims are also included for an electronic price display terminal and a method for operating a wireless chip module embedding an NFC function. The main block could be woken up on the basis of whether the RF signal contains an ID of the chip module S200'. The invention could find application in an electronic shelf label system (ESL). One of the aims of the invention is to reduce power consumption.
