Project(skip to here if you don't care): I wanna use the rfid tags as products that i send to a mobile app and from there a suite of different applications. I succeded with a mfrc522 but only for 3cm since that was max for that. Now i am looking to get at least 10cm and i bought the sparkfun rfid and id-la20.
Also, unrelated question. If i wanted to read with this setup and after that add a bluetooth send the id tag via bluetooth on an android app. Both bluetooth and rfid would be on software serial. I saw that uno supports only 1 serial at a time. My question. Should i get an arduino Mega?
