Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Please refer to fig. 1-3, in order to achieve the above object, the utility model provides a NFC, RFID two-in-one electronic tag, which comprises a bottom shell 1 and an upper shell 2, wherein a transparent window 3 is arranged in the middle of the upper shell, the upper shell 2 is of an ABS plastic structure, the middle transparent window 3 is of a PC material structure, the bottom shell 1 is of an ABS plastic structure, and is welded with the upper shell 2 into a whole by ultrasonic wave, an RFID tag circuit board 4 and an NFC tag circuit board 5 are sequentially arranged between the bottom shell 1 and the upper shell 2, the NFC tag circuit board 5 is used for displaying and changing first data information, and the first data information includes content information to be displayed which is edited by a communication device, such as a mobile phone; the RFID tag circuit board 4 is used for storing second data information including pre-stored related information about the article, such as information for article tracing. The NFC label circuit board comprises a first PCB substrate 501, the first PCB substrate 501 is of an FR-4 double-layer epoxy resin material structure, a main control chip 502 with the model of FMSC-DFN12 is arranged on the first PCB substrate 501, and the main control chip 502 is connected with an electronic ink screen 503, an NFC antenna 504 and resistor-capacitor related components; the RFID tag circuit board 4 comprises a second PCB substrate 401, an RFID chip 402 is arranged on the second PCB substrate 401, and the RFID chip 402 is connected with an RFID antenna 403.

The utility model discloses a theory of operation:

(1) NFC tag circuit board principle: after picture content needing to be displayed is edited by NFC communication equipment, such as a mobile phone, the NFC communication equipment is close to an NFC electronic tag, a transmission command is started, an NFC antenna of the NFC communication equipment can transmit 13.56MHz data signals to the NFC electronic tag, an NFC antenna 504 of the NFC electronic tag receives the signals through spatial coupling, the signals are decoded by a main control chip 502, and then display data are sent to an electronic ink screen 503 to be displayed. Because the NFC electronic tag has low power consumption, the electromagnetically coupled signal can be used as working energy and can also be used as a data signal. After the data transmission is finished, the NFC communication equipment can leave the electronic tag, and due to the characteristic of the electronic ink screen, the picture on the display screen can still be reserved after the power supply is turned off.

(2) The RFID tag circuit principle is as follows: when the RFID card reading equipment transmits 860-960 MHz radio frequency signals near the RFID electronic tag, the RFID chip 402 in the RFID electronic tag obtains energy through an electromagnetic field of an RFID antenna 403 to start working, communicates with the RFID card reading equipment based on a 18000-6C protocol, receives and transmits data, and the RFID card reading equipment transmits the read data to background software for data statistics and processing.

Through the combination of the NFC electronic tag and the RFID electronic tag, the display content of the NFC near field communication update electronic tag and the reading data of the RFID far field communication are integrated, the content can be displayed on site without being powered by a battery, and the NFC near field communication update electronic tag can also be remotely read for background data statistics and management, is environment-friendly and can replace the existing paper tag and the existing Bluetooth electronic tag.
