nfc multiple tags NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of electromagnetic pulses. A UHF RFID reader option for both Android and iOS is available from a company called U Grok It. It is just UHF, which is "non-NFC enabled Android", if that's what you meant. My apologies if you meant an NFC reader for Android devices that don't have an NFC reader built-in. Their reader has a range up to 7 meters (~21 feet).

nfc tag examples
NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of electromagnetic pulses. 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?
The PN532 is a very popular NFC reader chip made by NXP, and you can likely find a module that uses the chip from your favorite retailer. As Mendoza points out, the datasheet from NXP specifically states that the PN532 is capable of handling a maximum of two targets at once.
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?
Optimize UX flows for quick tag interactions – Provide clear scanning instructions and feedback for short NFC transactions. Support multiple tag types – Check the Android API to support anticipated tag formats like NDEF, Mifare, etc. 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. In the NFC communication protocol, when a device acts as a NFC reader (it provides its own field), it is waiting for a tag to approach. When this occurs, the reader energizes the tag and depending on the application, it can read from or write to a tag.
Ultimately, I'd like to be able to read data from multiple tags that enter the field simultaneously, but Android only seems to trigger on the first one that enters the field - subsequent ones are ignored.

Since the PN532 chip itself is surface mount and requires some external components to operate the best is probably to obtain a breakout board similar to the one below . See more
