W55MID50
A. W55MID50 is a function of MFID Reader IC. W55MID15 and W55MID35 automatically respond with
its ID when
it is coupled by magnetic resonance power from Reader.
Q. Is it possible to read multiple MFID chips in the same magnetic area?
A. W55MID35 has been implemented by "Anti-collision" algorithm to allow more than one IDs can be
simultaneously
recognized in the same magnetic area.
Q. How many W55MID35 IDs can be simultaneously read in the same magnetic area?
A. Actually, there is no any limitation in total number of W55MID35 tags can be simultaneously read, if
the Reader
system can provide sufficient coupled magnetic resonance power to every W55MID35 tag,
Q. Does anything interfere with MFID chip readout operation?
A. W55MID series is operating on 13.553 MHz ~ 13.567 MHz, therefore it is far away from 27 MHz and
2.45GHz.
There is no any interference with W55MIDseries.
