Hi, anyone else here uses the ID-20 Reader Module? I'd just like to know the range of your readers? Mine has an extremely short range of 5cm though the data sheet mentioned "up to 20cm".... Any way to increase the read range of the reader? (I'm using passive RFID tags btw)
Thanks
Be sure of the voltage... I think you can use 5.5v to increase read distance(check datasheet for max voltage).
To reach 20+cm you'll have to use an external antenna.
According to the datasheet it says it should use 5V?
What kind of external antenna do i use? can i buy that anywhere?
Datasheet says you can send 5.4V.
The antenna design is also written there.
