nfc read multiple tags My current project requires that I read two NFC tags at once. Diagram would look something like this: NFC_TAG_1 ----nfc reader---- NFC_TAG_2. Basically, NFC reader is in the middle, and there's one tag on each side of the reader. Which module is best suited for this? $149.00

NFC tags are powered by the NFC reader using magnetic coupling (so called near field). You need to research the use of much smaller loop antennas which will control the distance over which you can power the transponder NFC tags. I have one PN532 NFC/RFID and I need to read multiple tags to know how many .NFC tags are powered by the NFC reader using magnetic coupling (so called near field).

I have one PN532 NFC/RFID and I need to read multiple tags to know how many objects are near to PN532. In reading program example (from Arduino SDK) I can reading 2 tags in same time, but I want to read all tags, how can I do that?
My current project requires that I read two NFC tags at once. Diagram would look something like this: NFC_TAG_1 ----nfc reader---- NFC_TAG_2. Basically, NFC reader is in the middle, and there's one tag on each side of the reader. Which module is best suited for this?From reading the NFC spec (ISO/IEC 14443-3) for the tags I'm using (Mifare Classic), I should be able to send a 'halt' command to the tag, which will cause it to stop responding, and allow me to read the next tag in the field.
For the most part, NFC readers are intended to be used with just one card, tag, or chip at a time. The reason for that is pretty straightforward: readers work by emitting a radio signal that powers the NFC chip, and then checking the data that’s sent back. The idea is to trigger a media file when an NFC tag is detected by an RFID reader built into the game board, that tag remains on the gameboard. As new tags are added to the board each would play a separate media file, whilst the prev.
I am working on a project in which I need to detect two NFC tags simultaneously: A simple example to illustrate: When I detect Tag A, LED 1 turns on; when I detect Tag B, LED 2 turns on. If both tags are present both LEDs are on, if no tag is detected, LEDs are off. I am using an Adafruit PN532 board with an Arduino UNO. 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. You can find it on the RFID SHOP website.Reading multiple NFC tags simultaneously in Android can be an intricate task due to the inherent limitations of NFC technology itself. However, with proper handling, you can efficiently read multiple tags within an Android application.Extract and analyze NFC data sets (NDEF messages) Read out and display the complete tag memory layout; Supports for all kind of NFC Forum record types (let us know if you find anything missing) Explore details around contactless cards, tags and NFC-enabled item in general; Help mobile developers to detect configuration errors on contactless cards;
