The tag contains a small RFID chip and an antenna and is passively powered by the reader\/writer when placed a couple inches away.\u003cbr\u003e\u003cbr\u003e These can be read by almost any 13.56MHz RFID\/NFC reader, but make sure it can handle ISO\/IEC 14443 Type A cards (the standard NTAG uses) as there are a few other encoding standards (like FeLica).\u003c\/p\u003e \u003cp\u003eThese chips can be written to and store up to 144 bytes of data in writable EEPROM divided into 4 byte banks, and can handle over 10,000 re-writes. You can use our \u003ca href=\"http:\/\/www.adafruit.com\/products\/364\"\u003ePN532 NFC\/RFID breakout board\u003c\/a\u003e or \u003ca href=\"http:\/\/www.adafruit.com\/products\/789\"\u003eAdafruit NFC\/RFID Shield for Arduino\u003c\/a\u003e to read and write data to the EEPROM inside the tag. There is also a permanent 7-byte serial number ID burned into the chip that you can use to identify one tag from another - the ID number cannot be changed.\u003c\/p\u003e\n\u003cp\u003e These use an NTAG chipset, a 'Type 2' tag that is usable with any smartphone. \"Classic 1K\" cards (aka MiFare S50s), these tags are more secure and work with almost any phone with RFID support since they avoid the patent issues with MiFare, which requires an NXP chipset or license fee. \u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"video-insert\" alt=\"https:\/\/www.youtube.com\/embed\/vFJoolXpsfk?start=62\" contenteditable=\"false\" allowfullscreen=\"true\" frameborder=\"0\" src=\"https:\/\/img.youtube.com\/vi\/vFJoolXpsfk\/hqdefault.jpg\"\u003e\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"4-6 Days","offer_id":47700535738713,"sku":"ADA-5459\/B","price":4.32,"currency_code":"EUR","in_stock":true},{"title":"1 day","offer_id":47886599881049,"sku":"ADA-5459\/A","price":4.32,"currency_code":"EUR","in_stock":false},{"title":"2-4 Weeks","offer_id":47886773715289,"sku":"ADA-5459","price":4.32,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/1009\/7753\/files\/5459-01.jpg?v=1705521704","url":"https:\/\/robot-italy.com\/en\/products\/5459-ntag213-13-56mhz-rfid-nfc-clear-keychain-fob","provider":"Robot Italy","version":"1.0","type":"link"}
