125KHz RFID Coin Sticker Tag with 3M Stickers with Coins size of 25mm TK4100 Radio-frequency identification (RFID) uses electromagnetic fields as a result to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, basically a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. Especially this number can be used to track inventory of goods. Passive tags are powered by energy from the RFID reader’s interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. 125 Khz RFID Cards ID Sticker Coin Cards Chip Compatible For Access Control High quality pvc material Frequency: 125 KHz Size: 25mm x 1mm K4100(Compatible EM4100); Operating Frequency: 125KHz; Communication speed: 106K Boud Read distance: 2.5 ~ 10cm Read time: 1 ~ 2ms Operating Temperature: -20c ~ 85c Endurance:> 100,000 times The shell is made by excellent anti-corrosion and high temperature resistant material, RF chip is sealed in, filling the epoxy resin, and use ultrasonic to weld.
