RFID - Simple English Wikipedia, the free encyclopedia
Radio-frequency identification (RFID) is a technology to record the presence of an object using radio signals. It is used for inventory control or timing sporting events. RFID is not a replacement for the barcoding , but a complement for distant reading of codes. The technology is used for automatically identifying a person, a package or an item. To do this, it relies on RFID tags. These are small transponders (combined radio receiver and transmitter ) that will...

The RF in RFID: physical layer operation of passive UHF tags and readers
Daniel M. Dobkin
(revised Dec 2012)
6. RFID Protocols
A communications protocol is a way of organizing the conversation between devices -- in the case of RFID, between tags and a reader -- to ensure that information actually gets transferred. A protocol defines:
an air interface: what sort of modulation of the reader signal...

I am working on designing a small RFID reader circuit that is based on the PN532 chip and I would like to get some feedback. My background isn't RF engineering, so I am not sure about many things.
I'll summarize the main questions first, and then describe in details what I've done:
I am using miniVNA Tiny for taking measurements.
