RFID soft enamel card structure

The utility model discloses a RFID (Radio Frequency Identification) soft enamel card structure, comprising a first middle material layer and a second middle material layer, between which an embedding layer is arranged; the embedding layer is formed by a PCB underframe and antennas and a RFID chip arranged on the PCB underframe; the RFID chip and the antennas are connected to form a loop. According to the utility model, the PCB underframe is provided in a RFID card to correspondingly arrange the RFID chip and the antennas on the PCB underframe; reinforcement to the RFID card is realized through the PCB underframe, which prevents the card from deforming and depressing under high temperature, low temperature or other conditions and raises resistance of the RFID card and product stability.
