The DLP-RFID-UHF1B is a low-cost, USB-powered module for reading from and writing to ISO 18000-6a, -6b and -6c intelligent RFID transponder tags. It has the ability to both read and write data in addition to reading the unique identifier (UID). All of the DLP-RFID-UHF1Bs electronics reside within the compact unit, and all operational power is taken from the host PC via the USB interface. 2.0 RFID BASICS RFID stands for Radio Frequency IDentification. It is an electronic technology whereby digital data encoded in an RFID tag (or transponder) is retrieved utilizing a reader. In contrast to bar code technology, RFID systems do not require line-of-sight access to the tag in order to retrieve the tags data, and they are well suited to harsh environments. An RFID tag consists of an integrated circuit attached to an antenna. In the case of the tags used with the DLP-RFID-UHF1B, the antenna is in the form of conductive ink printed onto a material that allows for connection to the integrated circuit. This type of passive (battery-free) tag is commonly referred to as an inlay. The RFID reader (or interrogator) is typically a microcontroller-based radio transceiver that powers the tag with a time-varying electromagnetic radio frequency (RF) field. When the RF field passes through the tags antenna, AC voltage is generated in the antenna and rectified to supply power to the tag. Once powered, the tag can receive commands from the reader. The information stored in the tag can then be read by the reader and sent back to the host PC for processing. The data in the tag consists of a hard-coded, permanent serial number (or UID) and user memory that can be written to, read from and locked if desired. Once locked, user data can still be read but not changed. Rev 1.0 (November 2009) 2 DLP Design, Inc.
