Looking for suggestions on enhancing the read distance of SM130 module. The current read distance is 10cm. I would like to double or tripple this distance. Using
SM130 13.56 MHz RFID Module - http://www.sparkfun.com/datasheets/Sensors/ID/SM130.pdf
RFID Evaluation Shield - 13.56MHz
Enhance read distance
One of the possibile solutions would be to add a power amplifier and attenuator/buffer between the antenna and the SM130 Module.Example
SM130-->Power Amplifier -->Antenna --> Tag -->Antenna -->Attenuator/Buffer --> SM130
What do you think?
