Title:
ELECTRONIC PRICE TAG
Document Type and Number:
WIPO Patent Application WO/2023/179364
Kind Code:
A1
Abstract:
Disclosed in the present application is an electronic price tag. The electronic price tag comprises a passive NFC antenna, which is added at a position other than an electronic price tag PCB and has no electrical connection relationship with an existing NFC antenna, wherein the passive NFC antenna is coupled to an existing NFC antenna. By means of the present application, when the size of an electronic price tag is limited, and an NFC antenna is blocked by a screen, a battery, a structural member, etc., the NFC signal intensity and field intensity distribution near the screen of the electronic price tag are improved, thereby improving properties, such as the NFC communication distance, effective induction area and trigger response speed, of the price tag.
