{"product_id":"1356mhz-rfidnfc-bracelet-classic-1k","title":"13.56MHz RFID\/NFC Bracelet - Classic 1K","description":"\u003cp\u003eThis is a blank 13.56MHz RFID\/NFC silicone bracelet. 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\u003eThese can be read by almost any 13.56MHz RFID\/NFC reader but make sure it can handle ISO\/IEC 14443 Type A cards as there are a few other encoding standards (like FeLica) They are tested and work great with both our PN532 NFC\/RFID breakout board and Adafruit NFC\/RFID Shield for Arduino!\u003cbr\u003e\u003cbr\u003eThese chips can be written to \u0026amp; store up to 1 KB of data in writable EEPROM divided into banks, and can handle over 100,000 re-writes. You can use our PN532 NFC\/RFID breakout board or Adafruit NFC\/RFID Shield for Arduino to read and write data to the EEPROM inside the tag. There is also a permanent 4-byte ID burned into the chip that you can use to identify one tag from another - the ID number cannot be changed.\u003c\/p\u003e\u003cp\u003eThese use a ISO\/IEC 14443 Type A chipset, which used to be the 'classic' NFC chipset. In ~2014, the NFC forum decided not to support this chipset anymore, so newer phones do not support it. This only matters if you're trying to use this tag with a phone\/tablet.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eRFID chip specification:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 KiloByte (8 KiloBit) non-volatile EEPROM storage\u003c\/li\u003e\n\u003cli\u003eBuilt in encryption engine with 48-bit key\u003c\/li\u003e\n\u003cli\u003e4 Byte unique identifier burned into the chip\u003c\/li\u003e\n\u003cli\u003e13.56 MHz frequency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBracelet specification:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits wrists\/ankles\/hands up to 70mm (2.75\") diameter 25.4mm diameter\u003c\/li\u003e\n\u003cli\u003eBracelet made of rugged waterproof silicone\u003c\/li\u003e\n\u003cli\u003e0.9 grams \/ 0.03 oz\u003c\/li\u003e\n\u003cli\u003eWorks about 1\" away from reader\u003c\/li\u003e\n\u003cli\u003eWeight: 14.86g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493232279629,"sku":"ual1787257669837","price":2.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/1356mhz-rfidnfc-bracelet---classic-1k_1.jpg?v=1787257674","url":"https:\/\/www.grandorchard.shop\/products\/1356mhz-rfidnfc-bracelet-classic-1k","provider":"My Store","version":"1.0","type":"link"}
