{"title":"13.56MHz RFID/NFC Sticker [1KB]","handle":"13-56mhz-rfid-nfc-sticker-1kb","url":"/products/13-56mhz-rfid-nfc-sticker-1kb","description":"This blank 13.56 MHz RFID/NFC sticker contains a Mifare Classic 1K chip with 1 KB of writable EEPROM storage. The thin adhesive-backed form factor makes it easy to stick onto equipment, packaging, shelves, or any smooth surface for contactless identification and tracking. The embedded chip and antenna are passively powered — no battery is needed.\n\nThe chip stores data in writable EEPROM divided into banks and supports over 100,000 re-write cycles. A permanent 4-byte serial number is factory-burned into each chip for unique identification.\n\nKey Features\n\n\n1 KB Writable EEPROM – Divided into banks, supports 100,000+ write cycles\n\nPermanent 4-Byte UID – Factory-burned unique ID for identification (cannot be changed)\n\nAdhesive Sticker – Peel-and-stick for quick application on smooth surfaces\n\nPassive Operation – No battery required; powered by the reader's RF field\n\nISO/IEC 14443 Type A – Compatible with standard 13.56 MHz RFID readers\n\n\nSpecifications\n\n\nFrequency – 13.56 MHz\n\nChip – Mifare Classic 1K (ISO/IEC 14443 Type A)\n\nMemory – 1 KB writable EEPROM\n\nWrite Endurance – 100,000+ cycles\n\nUID – 4-byte permanent serial number\n\nForm Factor – Adhesive sticker\n\n\nIdeal For\n\nInventory and asset tracking\nEquipment and tool identification\nShelf labelling and stock management\nRFID reader/writer prototyping and testing\n\n\nPackage Contents\n\n1× RFID/NFC Sticker (1 KB)\n\n\n\nNote: This sticker uses the Mifare Classic chipset (ISO/IEC 14443 Type A). Since approximately 2014, the NFC Forum no longer supports this chipset, so most newer smartphones cannot read or write to it. This only affects phone/tablet use — dedicated RFID readers (such as PN532-based boards) work without issue.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11993,"title":"Default Title","sku":"AF-362","price":4.87,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
