DESCRIPTION
A pre-programmed code is transmitted to the reader by varying the amount of energy that is reflected back to the reader. It implements a robust and fast anticollision protocol. The chip is frequency independent and can be used for RF coupled applications where reading ranges in excess of 10 m and reading rates of 120 tags per second at 256 kbit/s can be attained. The chip is backscattering data using load modulation. Therefore the reader should be able to detect ASK and PSK modulated carrier. TypicalAPPLICATIONS
The chip is ideal for applications where long range, high-speed item identification is required:● Supply chain management
● Tracking and tracing
● Access control
● Asset control
● Licensing
● Auto-tolling
● Animal tagging
● Sports event timing
