Description of DQ310
1 SUMMARY
DQ310, an IC cards read and write module designed by small size, low power check card (LPCD) and easy operation. This RFID module can read the main part of smart cards.
The module and antenna is integrated.Easy to use，safety to opreate, It has various functions and terms multi ISO/IEC standard of contactless card.Widely used in office/home security, personal identity, entrance guard system, security systems, intelligent instruments and meters, interactive toys and production process control ,which a variety of wireless radio frequency identification (RFID) system.The PCB and antenna are connected by 50 ohm feeder, that convenient and easy to use.

4 ANTENNA DESIGN
We offer two standard size antennas, and the customer can customize the antenna according to the actual situation.
4.1 30mm*30mm Antenna
4.2 50mm*50mm Antenna
5 LOW POWER CHECK CARD
Keepping INT pin in high level or dangling situation，Module is normal working；
Using externalIO，put INT pin in low power level，Module is working in LPCD situation；
Putting the card in areas ofthe antenna，the module’s INT pin keeps in high power level.
The upper detects high level ,then needs to pull the IO up, themodule comes to normal operation .
