摘要： A Near Field Communication (NFC) tag and a control system for the NFC tag are provided. The NFC tag includes: a NFC coil, a control circuit, an energy acquisition circuit, and an energy storage circuit, wherein the NFC coil is configured to detect a magnetic field signal transmitted by a card reader when a distance between the NFC tag and the card reader is within a predetermined distance range; the energy acquisition circuit is configured to convert the magnetic field signal into an electrical signal when the NFC coil detects the magnetic field signal; and the control circuit is configured to control the energy acquisition circuit to transmit the electrical signal to the energy storage circuit, and control to charge the energy storage circuit through the electrical signal.

摘要： An electronic shelf label and a method for assembling the same. The electronic shelf label including: a housing (10), the housing including a front housing (12) and a rear housing (11), the front housing (12) and the rear housing (11) being coupled with each other, a chamber (13) being provided between the front housing (12) and the rear housing (11), the rear housing (11) including an opening (111); a motherboard (31), the motherboard (31) being located in the chamber; a back plate (32), the back plate (32) covering the opening (111), the motherboard (31) being detachably coupled to the back plate (32), the back plate (32) being detachably coupled to the rear housing (11), and an orthographic projection of the back plate (32) in a plane where the rear housing (11) is located being located in the rear housing (11). By reasonably setting the positions of the motherboard (31) and the back plate (32), the overall volume of the electronic shelf label is effectively reduced, and the beneficial effects of compact structure and easy installation are achieved.
