#Using the multi-activation system
When multi-activation is enabled, the device’s polling loop is altered to use the anti-collision of the protocols to activate more than one card at once.
The tracking loop is also altered to verify the presence of all the cards that have already been enumerated.
The device attributes a card index to every card it finds. Indexes are released (and potentially re-used) as soon as the corresponding cards does not answer to tracking anymore.
Remark: at firmware level, the device is theoritically able to activate up to 8 cards, but, depending on the antenna, RF environment, and on the cards themselves, there is only little chance to handle more than 3 cards at once.
When P1,P2=02,00 and Lc=00 (no DataIn), the device returns the multi-activation Status in DataOut.
The multi-activation Status is formated as follow:
- 1st byte gives the index of the currently selected card
- 2nd byte is a bit field that shows the list of found card(s) (1 bit per index; for instance,
0D means there are 3 cards, with indexes 0, 2 and 3).
When P1,P2=02,00 and Lc=01, DataIn is a single byte-value to select another card index.
The Tracking INStruction (P1,P2=02,01) runs one iteration of the tracking-loop and return the updated multi-activation Status.
This makes it possible to detect card removals.
The Tracking+Polling INStruction (P1,P2=02,03) runs one iteration of the tracking-loop, then one iteration of the polling loop, and return the updated multi-activation Status.
This makes it possible to detect card removals and card insertions.
