“If a farmer wants to count animals through a four-metre-wide gateway, two or more will be going through at once and that could result in shielding of signals or even double-counting of some tags. The situation is worse than that of trying to get all the goods on a pallet read as they enter a warehouse, McKenzie says. “The boxes on a pallet don’t move about all the time.” Animals contain water and blood, are covered with hair and may have horns, some of the most troublesome of radio-shielding substances. Deer particularly like to travel in bunches. The movement means the software relied on to prevent signal collisions with stationary or predictably moving goods does not work so well. Some trials have been done of the alternative RFID carrier, the bolus – a hollow pill that sits in the animal’s intestine; but that is less useful for meat processing, since the internal organs are extracted and the bolus must be “recovered”. You always know where the eartags are – on the animal’s head, Mackenzie says.”

Texas Instruments (TI) introduced a pair of encapsulated RFID mini-transponders designed for applications in animal tagging and asset tracking. The 12mm TRPGR30TGC and TRPGP40TGC mini-transponders were developed to enable users a battery-free solution for embedding RFID tags into smaller objects across a broader range of applications. These transponders come ready-to-use and are 100 percent backwards compatible with all of TI’s RFID software and readers including power modules, control modules and micro readers. read more »nanotron Technologies announced the release of nanoLES Version 2.0, the latest high throughput location engine and server software of nanotron’s people and asset locating (PAL) technology. read more »HID Global has developed a new a manufacturing process that enables use of some of the world’s smallest integrated low-frequency (LF) chips ever produced for contactless ID applications. read more »HID Global announced the debut of two new Glass Tag Ultra RFID transponders for animal identification and industrial applications. The HID Global design featured in the Glass Tag Ultra 134.2 kHz transponders use direct bonding technology and optimized chip placement to enable a boost of performance. Read ranges are improved by up to 35% compared to low frequency glass tags of the similar size. read more »Pethealth Inc. announced the roll out of an ISO-standard MiniChip for use with companion animal RFID applications. Approximately one-third the size of a standard microchip – which itself is roughly the size of a grain of rice - the MiniChip is designed to offer a smaller-scale alternative without compromising any of the protective benefits. read more »GAO RFID announced its handheld RFID reader series for animal identification and management, for applications such as stock breeding, animal control, or foodstuff tracking systems. read more » |
