We at Bartech Systems has a separate division were we design and implement various solutions based on Radio Frequency IDetification (RFID).

Radio-frequency identification (RFID) is a technology that uses communication via radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking. Some tags can be read from several meters away and beyond the line of sight of the reader.

RFID Frequencies
There are basically four frequency bands in which RFID works namely; LF, HF, UHF and Microwave.

LF or Low Frequency (100-500KHz): This frequency is used for short to medium read range at a low reading speed. Its advantages are its ability to penetrate obscuring materials and its inexpensive compared to other frequencies. Most suitable application areas are animal control, car immobilizer, access control and inventory control.

HF or High Frequency (10-15Mhz): Typically 13.56 MHz is used and it provides short to medium reading range at medium reading speed. It's potentially inexpensive and has moderate penetration in obscuring materials. Mainly finds use in the application areas like access control, pallet and carton identification and smart cards, Libraries, Jewellery etc.

UHF or Ultra High Frequency (860-950MHz): This frequency band has a comparatively long read range . It has high reading speed and is expensive compared to the other frequencies. It is ideal for applications like supply chain management, railroad car monitoring and toll collection systems.

Microwave Frequency (2.4-5.8Ghz): This frequency band and has a medium read range with moderate penetration ability in obscuring materials. It's relatively expensive compared to LF and HF. Microwave is most suitable for applications like carton and pallet identification.

RFID tags come in a wide variety of shapes and sizes. Animal tracking tags, inserted beneath the skin, can be as small as a pencil lead in diameter and one-half inch in length. Tags can be screw-shaped to identify trees or wooden items, or credit-card shaped for use in access applications. The anti-theft hard plastic tags attached to merchandise in stores are RFID tags. In addition, heavy-duty 5- by 4- by 2-inch rectangular transponders used to track intermodal containers or heavy machinery, trucks, and railroad cars for maintenance and tracking applications are RFID tags.

RFID tags are categorized as either active or passive. Active RFID tags are powered by an internal battery and are typically read/write, i.e., tag data can be rewritten and/or modified. An active tag's memory size varies according to application requirements; some systems operate with up to 1MB of memory. In a typical read/write RFID work-in-process system, a tag might give a machine a set of instructions, and the machine would then report its performance to the tag. This encoded data would then become part of the tagged part's history. The battery-supplied power of an active tag generally gives it a longer read range. The trade-off is greater size, greater cost, and a limited operational life (which may yield a maximum of 10 years, depend upon operating temperatures and battery type).

Passive RFID tags operate without a separate external power source and obtain operating power generated from the reader. Passive tags are consequently much lighter than active tags, less expensive, and offer a virtually unlimited operational lifetime. The tradeoff is that they have shorter read ranges than active tags and require a higher-powered reader. Read-only tags are typically passive and are programmed with a unique set of data (usually 32 to 128 bits) that cannot be modified. Read-only tags most often operate as a license plate into a database, in the same way as linear barcodes reference a database containing modifiable product-specific information.
