SecureRF Combines Security with Sensors

Sensors can be used to monitor a variety of environments but they need to be powered. SecureRF has developed a way to run sensors on battery–assisted passive (BAP) RFID tags and store the resulting data – up to 4Mbits of extended user memory - while meeting EPCglobal Class 1, Gen 2 standards.

BAP RFID tags, also known as semi-active tags, communicate using the same backscatter technique as passive tags and use a battery to run the circuitry on the microchip or an onboard sensor. BAP tags cost much less than an active RFID tag.

SecureRF’s LIME Tag can be equipped with a variety of sensors:

• Temperature
• Humidity
• Tamper indication
• Shock sensing
• pH levels
• Other sensors that are small enough to fit on a battery–assisted passive RFID tag
