Passive RFID Products

Passive RFID products can save man-hours through automation

Passive RFID offers superior performance when compared against traditional barcode systems.​

  • Range of up to 30 feet

  • Inexpensive tags

  • Read many tags simultaneously

  • Wide variety of configurations

Passive RFID is a perfect fit for many project types

Some project types are a very good fit for using passive RFID technology. Here are some examples of projects that are a good fit:

  • Periodic inventory with a handheld scanner is a perfect fit for passive RFID

  • Projects with predictable environments such as tool cribs

  • Asset tracking projects with choke points such as room entrances or building exits.

RFID Tags

The RFID Tag is the single most important component of a Passive RFID Tracking system. Various other hardware component choices can be made with Passive RFID, but any Passive RFID Tracking system will always have Passive RFID tags.

RFID Tags have a wide variety of performance characteristics ranging from only 1 foot  up to 30 feet or so. This wide variation is largely influenced by the size of the tag.

A general rule of thumb is that the smaller the RFID tag, the smaller the expected read range. These numbers correlate with manufacturer specifications as well as real-world data.

RFID Readers

A Passive RFID Tag will remain an inert object until it is powered by an RFID Reader. Various kinds of RFID Readers exist each tailored for specific applications.

Mobile Readers

Mobile Readers are handheld readers with RFID built into them. They are typically configured as an RFID gun where you pull the trigger to start reading RFID tags nearby.

Fixed Reader

Fixed Readers are designed to be mounted on a wall or ceiling. Fixed Readers have ports where RFID Antennas can be attached.

  • Different readers have a different number of ports. Typical configurations are two or four port readers.

  • Fixed Readers typically provide drivers to interface with the hardware.

RFID Printers

RFID Labels are paper labels that encapsulate the RFID Inlay. RFID Printers are designed to print human readable information on these labels as well as the capability of programming the RFID tag.

RFID printers come in three primary formats
  • Mobile RFID Printers - These are printers that are designed to be carried around, allowing printing on the go.

  • Desktop - Designed to be used in office type settings. These printers allow for a small to mid number of RFID tags to be printed.

  • Industrial - Industrial RFID Printers are designed for high volume printing of RFID tags. This type of printer would only be appropriate if printing more than 10,000 RFID tags per day.

Choosing the right combination of RFID Labels and RFID Printer is very important. Some RFID tags will only work with some RFID Printers.
