Veterinary Microchip Readers
UID designs and manufactures veterinary microchip readers. Both models read TraqPaw and compatible ISO FDX-B chips; choose the format support and read range your practice needs.
Why ISO?
Match the Reader to the Chip Format
ISO 11784 and ISO 11785 define animal identification coding and communication. Reader support still matters: match the chip's format to the reader's documented capabilities.
- Reads across brands: TraqPaw plus compatible ISO FDX-B microchips from other clinics, shelters, and rescues.
- HID keyboard mode: the number types into whichever PIMS or spreadsheet field has focus, with no scanning software to install.
- One number, one format: the same 15-digit ID whether the patient was chipped here or somewhere else.

Common Questions
-
Will our reader scan a chip from another clinic or shelter?
Both readers scan TraqPaw and compatible ISO FDX-B microchips. The URH-300HP-ISO also reads HDX tags. If your practice sees older non-ISO chips, contact us to confirm compatibility before you order.
-
USB or Bluetooth: which do we need?
USB if the reader stays at a fixed station next to the PC. Bluetooth if the operator moves between exam rooms, a procedure area, or for large animals. The URH-300HP-ISO offers Bluetooth as an option.
-
How does the number get into our PIMS?
In HID keyboard mode, the number drops into whichever PIMS or spreadsheet field has focus, the same way a keyboard types. Nothing to install. Serial output is available on the URH-2-ISO when your IT team needs the raw data stream instead.
-
Which reader do we need for horses or cattle?
The URH-300HP-ISO is built for the reach large-animal work needs, and its optional URH-PLEX antenna brings the antenna closer when access is limited.
-
Do we need special software to run these readers?
No. In HID keyboard mode, your PC treats the reader like a keyboard, so there is no separate scanning application to learn or install.
-
What's a typical reader pairing for a general practice?
PetScan (URH-2-ISO) fits routine dog and cat scans. Add a URH-300HP-ISO for larger animals or harder-to-reach implants.
