Abstract

The invention provides a wireless recharging RFID label. The wireless recharging RFID label comprises a wireless charging reception device, a charging cell, a cell electricity quantity indicator, an RFID integration circuit and an antenna of the RFID integration circuit, wherein the wireless charging reception device is connected with the charging cell, and the cell electricity quantity indicator is used for indicating electricity quantity of the charging cell. Compared with the prior art, the wireless charging technology is applied to an RFID label, so the charging cell in the wireless recharging RFID label can be charged by a wireless charging station when the electricity quantity of the charging cell is completely consumed or is in a low level, service life of the RFID label is prolonged, while an RFID label employing an internally-packaged cell in the prior art is discarded after the electricity quantity is consumed, and thereby reduction of environment cost and environmental protection are realized.

Description

technical field [0001] The invention relates to the field of RFID technology, in particular to a technology for wirelessly recharging RFID tags. Background technique [0002] RFID (Radio Frequency Identification, Radio Frequency Identification) equipment has been widely used. RFID tags with batteries that can be used for positioning, registration, etc. are usually designed as cards or wearable styles. The RFID card is packaged with batteries to prevent dust and water. If the battery is exhausted, the card has to be discarded. [0003] Wireless charging technology is very mature, but the technology has not been introduced into RFID tags at present. An RFID tag usually only works for 1-2 years, and its service life is limited by the life of the battery in the RFID tag. If the RFID tag is recharged through a wired connection, it is not conducive to the packaging of the RFID tag, and since the RFID tags have various appearances, it is also impossible to unify the charging int...
