CCD200 is a good solution for “One-Card-Total” solution with door access. When get down from car, proximity
card can be removed from transponder and used on doors access. When get onto car, card can be inserted
back into transponder for long range reading. CCD200 can also be used to upgrade existing site that are
already using normal card access – the same proximity card can be used back, just need to add AR500U and CCD200 transponder to achieve long range reading.

CCD200E support 125 KHz EM and CCD200M support 13.56 Mhz mifare proximity card. CCD200 is using
standard coin battery that is readily available from any electronic store. If the range seemed like unusually short,
please change the battery.
