Hi all,

anyone works with GP8F modules?
these are modules to read RFID Tags.

I'm working with GP8F-W5 (Weigand protocol)
These modules should detect RFID tags located as far as 10cm from the antenna.
I'm using its original antenna, but the detection distance is less than 3cm instead of 10cm!
Please help me improve its detection distance.

Anyone knows other cheap RFID reader modules?

Thanks a lot
