Passive electronic air luggage tag 丨 Electronic price tag 丨 ESL introduction Passive electronic air luggage tag uses NFC radio frequency wireless power to drive E-ink screen, realizing battery free electronic paper screen display, and can maintain image for a long time without battery

Passive electronic air luggage tags are powered wirelessly through NFC radio frequency, driving the E-ink screen to achieve battery free electronic paper screen display. They are aviation specific electronic luggage tags that can maintain images for a long time without the need for batteries.

NFC is a near-field communication standard that is currently standard on mainstream mobile phones, such as Apple, Huawei, Xiaomi, OV, etc., most of which have built-in NFC chips. The communication frequency of NFC is 13.56MHz. By coupling the coils in the same frequency band, RF energy can be converted into current, similar to the principle of wireless charging. The difference is that NFC is still a standard data transmission protocol, which can not only obtain energy, but also transmit communication data. The content information that needs to be displayed is transmitted to the CPU through NFC protocol and displayed on the screen.
