Pretoria-based iPico Holdings has released an ultra high frequency (UHF) radio frequency identification (RFID) technology solution aimed at overcoming bandwidth constraints and reader interference.
The solution, which operates in the 860-960MHz UHF frequency bands, as well as in the 2.45GHz microwave frequency band, overcomes two of the most common constraints associated with UHF RFID by using iPico`s iP-X anti-collision protocol and a tag-talks-only (TTO) approach.
The iP-X protocol can deal with up to 200 RFID tags simultaneously, enabling fast and reliable data transfer and the TTO approach enables RFID readers to operate in the same frequency channel without interference, according to iPico CEO Luther Erasmus.
"These readers occupy minimal spectrum space, allowing readers to operate in very high densities in highly populated regions with limited bandwidth, such as Europe and most Asian countries," explains Erasmus.
The iPico solution will send an alert if anyone attempts to tamper with the RFID tag, which, Erasmus claims, differentiates this product from others in the market.
"The ability to do off-line authentication using iPico`s patented data mapping processes combined with asymmetric PKI encryption technology, is a cost effective way for addressing security needs in various industries," he says.
The technology is designed for use in high-speed applications such as electronic vehicle identification, container identification and security, airline baggage tracking and document and product authentication.
Reading ranges for tags depend on the tag antenna type and packaging, as well as the reader power output and configuration, says Erasmus.
"Reading ranges for most systems will vary between two and six metres, but specially packaged industrial vehicle tags for transport and rail applications can be read reliably at up to 10 meters at speeds in excess of 200km/h," says Erasmus.
