NTAG215 NFC Sticker Tag – 25mm Round | 13.56MHz RFID for Android, Switch, Arduino এনট্যাগ ২১৫ এনএফসি স্টিকার – ২৫মিমি রাউন্ড | অ্যান্ড্রয়েড, সুইচ ও আরডুইনোতে কাজ করে

NTAG215 NFC স্টিকার ট্যাগে ৫০৪ বাইট মেমোরি আছে, যা NTAG213-এর চেয়ে অনেক বেশি। পুরো কন্টাক্ট কার্ড, একাধিক লিংক বা লম্বা নোট রাখা যায়। অ্যান্ড্রয়েড ফোন, আইফোন, নিন্টেন্ডো সুইচ এবং Arduino রিডারের সাথে কাজ করে।

What you can do with it

Extra memory gives you more to share with one tap.

Write your first tag in four steps

1. Install. Download a free NFC app such as NFC Tools on your phone.
2. Choose. Open the app, go to Write, and add the records you want, such as a link, a contact or text.
3. Write. Tap Write, then hold the back of your phone against the tag until the app confirms.
4. Stick. Place the sticker where you want it, and test it with a tap.

Good to know: NFC stickers do not work well directly on metal, so add a non-metal spacer or use an anti-metal tag. Locking a tag read-only is permanent, so test your content first. Use only content you have the right to use, especially for game-related projects.

Read tags with Arduino

An RC522 module reads NTAG215 tags. Wire it to an Arduino UNO: SDA to D10, SCK to D13, MOSI to D11, MISO to D12, RST to D9, 3.3V to 3.3V (not 5V) and GND to GND. Install the “MFRC522” library, then upload this sketch and tap a tag.

#include <SPI.h>
#include <MFRC522.h>
#define SS_PIN 10
#define RST_PIN 9
MFRC522 rfid(SS_PIN, RST_PIN);
void setup() {
  Serial.begin(9600);
  SPI.begin();
  rfid.PCD_Init();
  Serial.println("Tap a tag");
}
void loop() {
  if (!rfid.PICC_IsNewCardPresent() || !rfid.PICC_ReadCardSerial()) return;
  Serial.print("Tag ID:");
  for (byte i = 0; i < rfid.uid.size; i++) {
    Serial.print(rfid.uid.uidByte[i] < 0x10 ? " 0" : " ");
    Serial.print(rfid.uid.uidByte[i], HEX);
  }
  Serial.println();
  rfid.PICC_HaltA();
}

To see everything stored on the tag, use this sketch. It prints the tag type, the ID and all memory pages in the Serial Monitor.

#include <SPI.h>
#include <MFRC522.h>
MFRC522 rfid(10, 9);
void setup() {
  Serial.begin(9600);
  SPI.begin();
  rfid.PCD_Init();
}
void loop() {
  if (!rfid.PICC_IsNewCardPresent() || !rfid.PICC_ReadCardSerial()) return;
  rfid.PICC_DumpToSerial(&(rfid.uid));
  rfid.PICC_HaltA();
  delay(2000);
}
