detect multiple rfid tags at the same time I'm just starting a project using RFID tags to track cars and engines on a model railroad. Although I haven't gotten very far yet, my first thought was to use a multiplexer to select which reader I receive data from at any given time. Look at the machines around you and compare the card-reading slots and keypads. If they don’t look the same, some might be equipped with credit card skimmers. Inspect the lockable door on the .

simultaneously read rfid tags
I'm trying to find an RFID reader that is robust enough to simultaneously and consistently detect the presence (or absence) of multiple RFID tokens. I am writing to ask if anyone knows RFID readers that would be appropriate to detect the presence of multiple tags accurately and reliably? Thanks!

I've read about ISO14443A tags and that they should work with the RC522 RFID Arduino reader, however it's reading speed is slow. I have no need for a long reading range, quite small actually, all my tags are disposed separated from .The greatest feature is that the SRTR is able to read multiple tags at the same time. Additionally the read distance of tags is greatly increased (up to 16 feet!) from other readers. Did we mention you can write your own data to the tags?
If two tags are placed with one behind the other, the tag in front can block the signal of the one in back of it. If no energy reaches the tag behind, it can not be read. With high-frequency (HF) tags, a company called Magellan Technology has solved this issue using phased jitter modulation (PJM). Basically, the reader emits the read command, tags reply at different time intervals ("slots") after the command so they don't collide (when this happens, the reader gets garbled/superimposed data), and the reader is able to detect all of the tags present. If you want to detect multiple tags, you need to have a reader with anticollition protocol. I recommend using RFiD HF because the antenna design and debug is easier than UHF. You can use the OMNIKEY multi ISO reader which is a good product.

NFC enabled phones can ONLY read NFC and passive high frequency RFID (HF-RFID). These must be read at an extremely close range, .
