These so-called Smart Business Cards, or Digital Business Cards, use what’s known as NFC (Near Field Communication) to create a business card that can instantly transfer data, in this case, your personal and business information, allowing for an easy way for prospective business clients to get hold of your information at ease.

The closest I've gotten is to get the pages printed on one line with any empty . So I'm trying to make an Adafruit PN532 RFID shield function on an Arduino . I've been working on a project based on the Adafruit Babelfish tutorial, but have . i try to send text from PHONE via "NFC TOOL app" using PN532 (i2c) but i cant .
Whenever i place a valid card on the PN532, Card Detected! is printed on the serial monitor. . The closest I've gotten is to get the pages printed on one line with any empty spaces not printed, but if the string on the NFC tag is longer than 4 characters it still ends up coming into the serial as multiple chunks, which is messing me up down the line when I'm having another program (Node-Red) to look for the entire string. When I run it (which means that I put the NFC tag (came with the package) on the shield, it seems that it is stuck in this line and never reads the firmware version. uint32_t versiondata = nfc.getFirmwareVersion(); The problem is that some functions in the main-loop can not be executed because it gets stuck before, until a card is detected. I've heard about the IRQ pin and I've tried to read it but it doesn't worked.
I've been working on a project based on the Adafruit Babelfish tutorial, but have been encountering some interesting problems when trying to get it to recognize multiple RFID cards. I made a post over on the Adafruit for.Whenever i place a valid card on the PN532, Card Detected! is printed on the serial monitor. However, when i remove the card, Card Not Detected or Removed! does not get printed. How can i make the program to loop in such a way that it can detect when the card is present/removed? The problem seems to comes when they are combined. All of the Serial.println ("loop test") in the loop are my attempt to troubleshoot and figure out where the program is getting stuck. I would move it around and reload the program and watch the serial monitor to see where it would get stuck. I am looking for guidance and suggestions on how to fix an SPI conflict between the Adafruit 2.8" TFT Touch Cap shield and Seeedstudio NFC Shield v2. Both are working fine on their individual sketches, even when stacked and connected at the same time.
I activated the debug function from NFC library and it looks like the second APDU is not sent because of timeout. I went to the in nfc.inDataExchange function and i tried to modify the send timeout but without success. i am stuck . Below is the answer on serial from shield : I got an interrupt, when I set the nfc.SAMconfig(); in the void setup() After that one card reading is "available", but after that I never get interrupt. I only get interrupt, when I disconnect the interrupt connection from Arduino. I'm trying to write and read data on MiFare Classic 1K cards using the Arduino RFID/NFC shield, Arduino Uno, and the 12C library. The problem is that once I've written data to a card, I can no longer read the data.

Near Field Communication (NFC) is a contactless communication technology operating over a radio using a base frequency of 13.56 MHz with a typical range of up to 2cm and data rate from 46kbit/s up to 1.7Mbp/s. In addition to data connections, NFC is unique in that one side can also transmit power over the connection allowing for battery-less .
