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 di"cult 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
