What is RFID?RFID, Radio Frequency IDentification, uses radio frequency communication to automatically identify, track and manage objects, people, or animals.A passive (no battery) low-frequency (125kHz) ‘magnetically coupled’ RFID system is made up of two parts - a reader and tag.The tags are attached to objects or animals that require a unique identification number. The tags include an electronic circuit (transponder) and tuned antenna-capacitor circuit. The tags are small sophisticated radio transmitters and receivers. They are powered by the RF field generated by the reader. Upon being ‘powered-up’ the tag will continuously transmit, by damping the incoming RF power field, its data. By ‘pulsing’ the incoming RF power field some tags can be written to in the field.The RFID reader has three main functions: energizing, demodulating and decoding. The reader, using a tuned antenna-capacitor circuit, emits a low-frequency radio wave field. This is used to power up the tag. The information sent by the tag must be demodulated (like an AM radio). The encoded information is decoded by the reader’s on-board microcontroller. This information can then be used by a controlling computer.In both the reader and tag, the antenna can be sized and shaped in different ways. Because of the small size of the tag, it can be formed to fit almost any situation. Since there is no contact or ‘viewing’ required, the RFID system allows great freedom of movement. Placement of the tag and reader are no longer critical.PALCO can help you meet you RFID needs. Please contact us for specific information.
