So im going to use rfid, i try to use rfid passive disc tag, but then im confuse about rfid reader that can read at a long range, after searching at google i found it can be make, but i still confuse, if you guys have some guide, advice, reference or you have done this before, or if you guys have a better component that should i use, please tell me, im stuck because this is for my final exam. Thank you so much
