3ALogics RFID Reader Devices

3ALogics designs and manufactures highly integrated multi-protocol reader ICs for contactless communication at 13.56MHz. RFID Technology Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves reflected back from the RFID tag into digital information that can then be passed on to computers that can make use of it. 3ALogics RFID Brochure Tag A microchip attached to an antenna that is packaged in a way that it can be applied to an object. The tag picks up signals from and sends signals to a reader. The tag contains a unique serial number, but may have other information, such as a customers' account number. Tags come in many forms, such as smart labels that can have a barcode printed on it, or the tag can simply be mounted inside a carton or embedded in plastic. RFID tags can be active, passive or semi-passive. Reader A device used to communicate with RFID tags. The reader has one or more antennas, which emit radio waves and receive signals back from the tag. The RF energy from the reader antenna is "harvested" by the antenna in the tag and is used to power up the microchip, which then changes the electrical load on the antenna to reflect back its own signals.
