I had the NES one from a few years ago that didn't come with the functionality, so I was pretty .
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 . 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 .
When there is only a single NFC tag within range of the transceiver, all functionality works flawlessly (ie. inventory, stay quiet, read, write, read-multiple, reset to ready). Now I am .I try to use 2 PN532 NFC/RFID Readers at the same time. The problem is if I use both of them the program fails or can't find any devices. I tried I2C and SPI but nothing works. NFC is generally used for opening doors and making payments, so there is usually no real need to read two cards at the same time. But, if . 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 .

Arduino: Read Simultaneously RFID TAG with multiple RFID Reader [MFRC522]Helpful? Please support me on Patreon: https://www.patreon.com/roelvandepaarWith th. I'm interested in the possibility of a communications protocol that allows an NFC transceiver to communicate with more than one tag at the same time, or, at very least, to be . 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, .

the Read Multiple Blocks command (23h) supports up to 256 blocks (the number of blocks is encoded minus 1 thus value 255 means 256 blocks). The ST25DV04KC has a 4Kbit .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 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? When there is only a single NFC tag within range of the transceiver, all functionality works flawlessly (ie. inventory, stay quiet, read, write, read-multiple, reset to ready). Now I am attempting to read multiple NFC tags at the same time.

I try to use 2 PN532 NFC/RFID Readers at the same time. The problem is if I use both of them the program fails or can't find any devices. I tried I2C and SPI but nothing works.NFC is generally used for opening doors and making payments, so there is usually no real need to read two cards at the same time. But, if you’ve got a situation where you want to, Salvador Mendoza has a tutorial that explains how to do it . 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.
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? 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'm interested in the possibility of a communications protocol that allows an NFC transceiver to communicate with more than one tag at the same time, or, at very least, to be able to choose to communicate with a specific tag while there are multiple within its range.
