nodemcu not reading rfid after some time However, after setting up the circuit according to the datasheet and running the library main code "AccessControl", the RFID completely stops reading cards. It only works . This works without rooting the phone. I believe that some (not all) phone hardware might be able to emulate one other type of Tag if you have rooted the phone and know the non public API to access the hardware in the right manner (not confirmed).

All that's left is to check that your NFC business card works. Holding the card near a friend's smartphone should be enough to trigger the link to appear, asking if they would like to open the URL in a web browser. From there, they will be able to see your digital . See more
rfid stops reading after 540
it read the tags just fine for a few moments, it did what it was supposed to and dumped the info from the RFID Tag into the serial monitor, and suddenly it stopped reading .
Well let’s make a simple NodeMCU RFID reader using the MFRC522 module, and program the NodeMCU to provide access when the right card is detected. This simple example will read . However, after setting up the circuit according to the datasheet and running the library main code "AccessControl", the RFID completely stops reading cards. It only works . The RC522 module stops reading cards after running for a long time, about two weeks. After pressing the reset button of the ESP32 module, the module started reading cards .

rfid reader stops reading cards
The module is based on the MFRC522 chip from NXP, which supports various RFID protocols, including ISO/IEC 14443 A/MIFARE, ISO/IEC 7816, and FeliCa. This module works on .
In this tutorial we will learn How to interface NodeMCU with RC522 RF ID Reader using Arduino library for MFRC522 and other RFID RC522 based modules. This library read . In this article, I will make a tutorial on how to use this RFID reader with a nodeMCU. We can use the same library that was made by miguel just like what we did with an Arduino.I have re-checked the connections a thousand time but it's not working, the pins are connected as the example says to, and the LED D1 is on (red). Does anyone can help me? For some time I wanted to have an Arduino controlled light switcher for outdoors and few weeks ago I created it, but I have problems with it. I needed to have a RFID reader .

it read the tags just fine for a few moments, it did what it was supposed to and dumped the info from the RFID Tag into the serial monitor, and suddenly it stopped reading them. Here's the example code, only modification was changing .Well let’s make a simple NodeMCU RFID reader using the MFRC522 module, and program the NodeMCU to provide access when the right card is detected. This simple example will read the serial number on the Card or Tag, display it in the serial monitor. However, after setting up the circuit according to the datasheet and running the library main code "AccessControl", the RFID completely stops reading cards. It only works again after restarting it (and sometimes, it takes more than one attempt).
The RC522 module stops reading cards after running for a long time, about two weeks. After pressing the reset button of the ESP32 module, the module started reading cards again. 1 - The RC522 stops reading the cards after several reads and will only work again if i reset or reupload the sketch. The number of attempts is random but it ranges from 2-7 times.ESP8266/NodeMCU unable to communicate with MFRC522 RFID reader. I am trying to use the 'DumpInfo.ino' example file to dump an rfid tag, the only changes i have made to the example is changing the pin settings.

It successfully connects with WiFi (that I can see via serial monitor) but gives no response when I touch the RFID card to the reader and there is no display of the card UID in the PHP web app.
The module is based on the MFRC522 chip from NXP, which supports various RFID protocols, including ISO/IEC 14443 A/MIFARE, ISO/IEC 7816, and FeliCa. This module works on 13.56MHz frequency and communicates using I2C and SPI interface protocols. It operates on a +3.3V/13-26mA Power Supply.
In this tutorial we will learn How to interface NodeMCU with RC522 RF ID Reader using Arduino library for MFRC522 and other RFID RC522 based modules. This library read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino or NodeMCU using a RC522 based reader connected via the Serial Peripheral Interface (SPI .

1. RFID and NFC are the Same Things. The resemblances exhibited by RFID and NFC technologies do not mean they are similar technologies, even though one can argue they are born from the same cloth. .In order to leverage NFC verification, the user must opt to use their passport as their proof of identity. If they select a different option, such as a driver’s license or ID card without NFC technology, NFC verifications will not .NTAG215 NFC Inkjet Print Cards both sides can be printed compatible with .
