Our RFID experience covers the full range of frequencies used in RFID as well as a wide range of encrypted transponder devices. RFID solutions enable you to advance your business to a new level of efficiency by providing greater visibility into your inventory as it moves across the supply chain. With real-time tracking information, you’ll always know where your critical business assets are located.
The RFID device serves the same purpose as a bar code or a magnetic strip on the back of a credit card or ATM card; it provides a unique identifier for that object. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information. The differentiating factors to consider when choosing the most suitable device is how far away the object will be from the device and the number of objects that need to be scanned in one read.
Ultra High Frequency (UHF, 850MHz-950MHz)
Ultra High Frequency RFID utilizes the 860 to 930MHz band – typically 868 MHz in Europe and 915 MHz in North America. Read range is up to 3m (9.5 ft) and the data transfer rate is faster than HF systems. The primary rationale for utilizing this frequency is the greater read range.
Typical applications for UHF frequency RFID devices include: Supermarket and warehouse inventory control, motorway tolls.
High Frequency (HF, 13.56MHz)
High Frequency RFID systems operate at 13.56 MHz, and feature a greater read range and higher-read speed than LF systems. Typical read range is less than 1 meter (3 feet).
Typical applications for High Frequency RFID devices include: smart cards and smart shelves for item level tracking, library books, healthcare patients, product authentication and airline baggage. Another common application is maintenance data logging for sensitive equipment that needs regular checking.
Low Frequency (LF, 125kHz–134kHz)
Low Frequency RFID systems are typically 125 KHz, though there are systems operating at 134 KHz as well. This frequency band provides a shorter read range (< 0.5m or 1.5 ft) and slower read speed than the higher frequencies.
Typical applications for Low Frequency RFID devices include: access control, animal tracking, vehicle immobilizers, healthcare applications, product authentication and various point-of-sale.
