RFID Microchip and Transponder Manufacturer
UID designs, engineers, and manufactures animal identification microchips, PIT tags, industrial transponders, readers, and antennas. Hardware is assembled in the USA, with AEG ID engineering and manufacturing operations in Europe.
- Assembled in the USA
UID by the Numbers
- 3M+ RFIDs deployed
- 400+ Customers
- 30+ Years in identification
- USA Assembled in the USA
Our Own Design, Our Own Supply
We design and engineer our own transponders, readers, and antennas, write the software that reads them, and assemble the hardware in the USA. Owning design through assembly is what lets us hold quality and lead times, keep older products in service, and build to spec when the catalog doesn't already have your answer.
- Assembled in the USA — the hardware is built here, not rebadged from someone else's catalog.
- Operations in Germany and Czechia — European operations stand behind the supply chain.
- AEG ID, in the family — UID acquired AEG ID to widen the catalog we can build from.
- 30+ years of RFID — three decades of identification work goes into the catalog, and we keep adding to it.
Cited in Peer-Reviewed Research
Researchers and labs have published peer-reviewed work using UID transponders, readers, and monitoring systems. Each citation links back to the product it used. Independent results, not our own marketing.

A nutrient-hormone axis pivots an energy trade-off between resting thermogenesis and movement expenditure
- uct-2112
This mouse study asked why protein-dilute diets raise resting energy expenditure yet improve weight-bearing exercise. Dietary protein dilution increased liver-derived FGF21 and brown-fat…

A Preoptic Neurocircuit That Modulates Metabolic Flexibility
- uct-2112
This study identified torpor-associated glutamatergic PACAP neurons in the anteroventral preoptic area as a central controller of fuel selection in mice. Activating the neurons rapidly shifted…

A tail of two torpors: insight from autonomic and behavioural thermoregulation
- uct-2112
This poster compared natural fasting-induced torpor with a synthetic state produced by activating preoptic neurons in mice. Synthetic torpor caused tail vasodilation and a preference for warmer…

Arousal from torpor advances circadian phase without effect on period in mice
- uct-2112
This poster tested whether fasting-induced or chemogenetically induced torpor resets the circadian clock in mice. Wheel-running and core-temperature records in constant darkness showed that neither…
