Microwave RFID systems use a combination of circuits that use RF or microwave energy to provide a means of identification.
These systems can be applied to identify people or objects, using a microchip to store information. A serial number, for example, or other information about a person or product, is connected to an antenna for transmission.
The device that stores the information is called an RFID tag. The tag contains a unique serial number but may have other information to facilitate identification.
Different types of tags can read from 300 feet or more and are more expensive than other types of tags. Other tags receive energy when the chip’s antenna receives RF waves from a reader. The energy changes into an electrical signal that allows it to send information.
Other tags remain inactive until activated by a signal like RFID card access. These tags allow to extend the helpful life of the labels since energy can uses efficiently.
Automatic device identification
Microwave RFID systems provide access that does not compromise security. It is possible to use systems to separate services from each other and general system administration.
Most popular access control devices can also collect and manage data. Most RFID tags contain digital information on a microchip. Still, other chapless tags use the material to reflect a portion of the signal transmitted to them.
Chapless labels use conductive materials or materials that reflect a complete part of the wave radiated to them. A computer then generates an image of the reflected energy. It uses it as a fingerprint to identify the item or recognize the object in RFID access.
This microwave technology also allows for automatic reporting, providing a complete audit trail that helps validate compliance with regulations.
