The TempyTag is a low-cost, high-performance, high-security, temperature logging system including track and trace facilities.

The TempyTag is equipped with a temperature sensor, a microcontroller, a wireless (NFC and Bluetooth Low Energy) transmitter and receiver, and a printed aerial. Each card has a unique ID that can be used for tracking and tracing purposes.

The TempyTag can be programmed with user-specific data via its NFC or BLE interface and the data stored can be read via either interface by using the TempyApp™ on a Smart phone or by using the TempyScan™ application on a PC or laptop. TempyScanTM, a dedicated programming and scanning unit, is suitable for use in pharmacies and offers extra features for professional users.
