The ReadySense Passive RFID Temperature Sensor Tags are much smaller, thinner, and more flexible than battery-powered sensors, and they are more cost-efficient than active wireless sensing tags. With the ability to access and collect data, these RFID labels enable users to consistently monitor temperatures and provide critical information to help make informed decisions.
What is the high temperature RFID tag? – High-temperature RFID tags are specially designed to withstand extreme heat, often up to 250°C (482°F) or higher, without compromising performance.
Can RFID tags track temperature? – Yes, RFID tags equipped with temperature sensors can monitor and track temperature data in real-time. These tags are widely used in industries like healthcare, food logistics, and pharmaceuticals to ensure temperature-sensitive goods remain within safe ranges during storage and transit.
| Material | Polyester |
| Serialization | Barcode and human-readable equivalent is digitally printed - providing excellent clarity and easy scanning. Code 39 is the standard symbology with a range of 2.7 to 9.4 CPI (characters per inch). Optional linear and 2D symbologies available. Although this product is primarily marketed as a barcode product, we can produce it with human-readable numbers only or unserialized. |
| Label Copy | The label copy may include block type, stylized type, logos or other designs |
| Colors | Standard colors include black, red, yellow, green or blue. Custom spot colors are also available at no additional charge. Due to contrast needed for the barcode scanner, all barcodes are black. |
| Standard Adhesive | High performance adhesive |
| Sizes | 4.1875" x 1.125" |
| Packaging | Shipped on convenient rolls with scrap matrix removed for ease of removal. Cartons are clearly marked to indicate serial numbers of labels. |
Chemical Testing Summary
The ReadySense temperature tags were attached to a sheet of glass submerged in various chemicals. Observations were made at the following intervals: 2 hours, 24 hours, 48 hours. A Motorola handheld RFID reader as well as a handheld barcode reader were used to test the samples.

Temperature Testing Summary
High-temperature resistance test: These tags were attached to a sheet of glass at raised temperatures for 15 minutes. Tags were then removed from the oven and tested for readability immediately. Low-temperature resistance test - The tags were attached to a sheet of glass and exposed to -40 °F for 24 hours. Tags were then checked for readability with a handheld RFID reader. All samples were readable while at temperature just prior to removal from the freezer. No tag construction defects were observed and the adhesive still had a strong bond while in the freezer.
Temperature Testing Data
| Temperature | RFID read test (after sample cooled to room temp) | Appearance of tags |
|---|---|---|
| 200°F | Reads well | No change |
| 300°F | Reads well | No change |
| 400°F | Reads well | Tag distorted |
| 500°F | Reads well | Tag destroyed |
