Security Measures and Quality of Service
Security Measures:
The communication between the Reader and Sensor during a scan is a short range Near Field
Communication (NFC) method which makes it difficult to interfere with or intercept during
transmission. The transmitted data is protected by a proprietary data format, encryption, and
memory map. The integrity of transmitted data is ensured by a cyclic redundancy check (CRC)
generated by the Sensor and verified by the Reader. The communication between the Reader and
Sensor for Alarm data is a standard Bluetooth Low Energy (BLE) connection. The pairing of the
Sensor to the Reader is accomplished during activation with an authenticated login procedure that
uses an Out-of-band key exchange (NFC). This prevents unauthorized devices from connecting to
the Sensor. The transmitted data is protected by a proprietary data format and encryption. This
The Reader has a mean use life of
3 years, which is 156 cleaning and
disinfection cycles (1 cycle per week
for 3 years).
