RFID -- Radio Frequency Identification
Tag or Chip
A tag is a passive RFID device containing
a chip and antenna. A chip is the microchip inside
Tag is the correct terminology to use when referencing any
sports timing device used on the shoe.
We call ours a Sportag.
How does it work?
The system is very simple. Our Sportag contains
a microchip and two antenna loopsone to wake-up
the tag and the other to send its signal. When the tag comes
into contact with the antenna mat, it wakes up and starts
sending its unique signal again and again to the reader. The
IP-X Dual Frequency RFID Sportag overcomes the limitations
experienced by conventional Reader-Talk-First sport timing
systems. By combining two technologiesDual Frequency
(DF ) and the IP-X RFID interface with passive tags we are
able to achieve unmatched performance. Great Results, Every
Dual Frequency: DF is a combination of low frequency
and high frequencytaking the best properties of both.
That means passive tags are energized at long distances, while
tag IDs are received at high speeds. The passive tags are
energized at 125KHz, allowing a long range charge-up, and
they backscatter their IDs at 6.8MHz, allowing for fast read
IP-X is a reliable anti-collision protocol,
which allows high volumes of tags to be read simultaneously.
