The term RFID (Radio-Frequency Identification) describes the use of radio frequency signals to provide automatic identification of items. RFID is similar to bar code technology with additional benefits such as:
- Non-contact, non-line-of-sight reading.
- Read/Write capabilities.
- Ability to function under a variety of environmental conditions.
- Provides a high-level of data integrity.
A bar code system uses a reader to read a bar code label. RFID uses a reader and special RFID tags or labels that are attached to the item. RFID often co-exists with a bar code data capture system. An RFID system typically includes the following components:
- An RFID transponder or tag that contains data about an item.
- An antenna used to transmit the RF signals between the reader and the RFID device.
- An RF transceiver that generates the RF signals.
- A reader that receives RF transmissions from an RFID devices and passes the data to the host for processing. (This may be a fixed portal or a mobile handheld computer with RFID reader.)
- Application-specific software to manage the information.
When evaluating RFID for solving a business process problem, consider the following:
RFID is constantly changing. Adoption is still relatively new. Bar code technology will probably always be more cost-effective; however, RFID opens the doors to automation and mobilization of data capture where bar code technology is not effective.
