Hi, recently i have read about RS232 Module and antennas UHF (Serial), i need make a RFID reader with Arduino Mega that have a range of 1m, 0,5m... On minimal it.
Currently i'm using RC522 with tags classics, but, this range is aproximately 3cm, or less yet it. Bad.
Is possible use a long range UHF and RS232 (Or others any modules) that use tags rfid. Or other devices to the use read tags long range?
