what happens if an rfid reader pickups multiple rfids Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one from another. The ACR1255U-J1 ACS Secure Bluetooth® NFC Reader supports ISO 14443 Type A and B smart cards, MIFARE®, FeliCa, and most NFC tags and devices compliant with ISO 18092 standard. The ACR1255U-J1 has both .

Easily reading data from RFID tags allows you to identify single items or entire .How RFID Readers Simultaneously Read Multiple Tags. When an RFID reader wants to read . Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one from another.
As far as I can tell the majority of RFID readers don't support reading multiple cards at the same time. I've used 5 different ones and they all behaved the same way. The reason I'm guessing is to avoid reading the same card multiple times by accident. "In the context of RFID, anti-collision refers to different ways to keep radio waves from one device from interfering with radio waves from another device. RFID readers may make use of anti-collision algorithms to enable a single reader to read more than one tag in the reader's field". This is taken from here I have problems with multiple RFID (MFRC522) usage. I use the MFRC522.h library from GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522, and I want to read 8 RFID modules with one Arduino Uno, but I have managed only 2! I connect all the SPI pins, SS1 to pin10 and SS2 to pin2. 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 .
By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come up with a method of triggering a device (like an electronic door lock) only when the appropriate combination of RFID. The only real problem inherent to reading multiple tags is having them block each other. 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.
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.
Hi guys, i have a project that used two RFID Reader, the project for counting tag from conveyor, in this case the reader is placed in the middle of the conveyor and the reader faces each other. So i have question, can two RFID Reader reading one or many tag simultaneously?
In this tutorial, we'll show you how to set up the SparkFun Simultaneous RFID Reader to take multiple, if not nearly unlimited, RFID readings simultaneously by connecting either the M7E Hecto or M6E Nano directly to your computer using a USB-C connection and running Universal Reader Assistant (URA) software, which provides a simple and . Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one from another.
