ReadySense Passive RFID Temperature Sensor Tags deliver a powerful solution for organizations that need accurate, reliable, and cost-effective temperature monitoring. Unlike bulky battery-powered devices, these passive RFID sensors are smaller, thinner, and more flexible—making them easy to apply to products, packaging, or equipment in virtually any environment.
Because they require no internal power source, ReadySense RFID labels offer greater affordability and scalability compared to active wireless sensing tags. This allows businesses to deploy temperature monitoring on a much larger scale without sacrificing accuracy or performance.
When scanned with a compatible RFID reader, these tags provide instant access to precise temperature data. That real-time insight helps users track environmental conditions, maintain compliance, reduce spoilage, and make faster, more informed decisions.

| 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.
