Universal RFID Asset Tag


  • Patented inlay design obtains excellent read range regardless of surface – metal, plastic, even wood
  • Lowest profile in its class makes label unobtrusive
  • Subsurface printing on durable polyester protects printed copy against moderate solvents and caustics/acids
  • Digital printing process provides for greater print capability with detailed logos or special designs
  • Compatible with RFID Tracking Software

The closest thing you will find to a "one-size-fits-all” RFID solution! The Universal RFID Asset Tag is a surface-independent tag that uses a patented inlay design and passive RFID technology to obtain excellent read ranges regardless of the surface – metal, plastic, even wood. Along with the Universal Mini RFID Tag, the Universal RFID Hard Tag, Universal Micro RFID Tag and the Universal MC RFID Tag, these products make up a revolutionary product line that allows you to use only one RFID tag for your asset tracking application.

The Universal RFID Asset Tag features an inlay design that offers the lowest profile of any tags in its class – solving a common issue many customers have with other metal mount RFID tags where a thick standoff creates an obtrusive nuisance for the user.

This unique inlay adheres to a subsurface printed label constructed of durable, yet flexible polyester. This process protects the copy, logo and/or barcode against moderate solvents and caustics/acids while our four-color processing capabilities allow you to promote your company with a label that shows off your company name or logo. Our digital printing process ensures even the most detailed logos will look crisp and clean.

Potential Applications for Universal RFID Asset Tags

Asset Tracking – the barcode and human readable ID number on Universal RFID Asset Tag can be used to track information about the metal asset the RFID tag is adhered to i.e., laptops, furniture, containers, equipment and more.

Work-in-Process – the barcode and/or identification number on Universal RFID Asset Tag can identify a “batch” OR “lot” of product or just simply identify each product as it travels through the production process.

Specifications Data
Material.002” thick polyester label adhered to proprietary inlay wrapped around 1/16” closed cell foam. Total product thickness is approximately .085”
SerializationBar code and human-readable equivalent are produced using the latest high-resolution digital technology available, which provides excellent clarity and easy scanning.Code 39 is the standard symbology with a range of 2.7 to 5.4 CPI (characters per inch). Optional symbology is Code 128.
Label CopyThe label copy may include block type, stylized type, logos or other designs. All copy, block type, stylized type, logos, designs, and bar code are subsurface printed. This unique process provides moderate resistance to solvents, caustics, acids and abrasion.
ColorsStandard colors include black, red, yellow, green, dark blue, orange, purple and blue. Due to contrast needed for the bar code scanner, all bar codes are black.
Standard AdhesivePressure-sensitive acrylic adhesive
Frequency RangeCustom designed UHF inlay optimized for use at 915 MHz. ( UHF, Class I Gen 2 )
Sizes2.875" x 1.375"

Destructive Test Data
Chemical Test Summary
In all cases, after 3 weeks soaking in these chemicals, all the tags and labels responded properly when interrogated with a handheld RFID reader, and all the bar codes except those soaked in acetone were readable with a standard bar code reader.

Temperature Test Summary
Heat Testing - Product withstood temperatures up to 240°F (115°C) for short term (10 minute) periods. They will withstand temperatures up to 160°F (71°C) for extended periods (tested for six hours with no degredation). The tests demonstrated that the transponder was not readable at temperatures above 185°F (85°C), but resumed function when temperatures were once again reduced below 185°F (85°C).

Cold Testing - Tags were tested outdoors at 0°F and were readable, but read distance was reduced to half of the read distance observed at 60°F (15°C).
