These are, by far, the most common type of transponder you'll see used in hotels. The 1k version has a 4-byte UID. While MFC was once considered secure, the proprietary \"crypto1\" it relies on was broken long ago making these transponders easy to clone. NDEF records, as specified by the NFC Forum, can be set but many applications will not work with them as these are not officially supported by MIFARE Classic.\u003cbr\u003e\u003c\/p\u003e","products":[{"product_id":"flexm1-v2","title":"flexM1 “Magic” 1k v2","description":"\u003cp\u003eThe flexM1 v2 is a Mifare \"Classic\" S50 1k chip emulator with writable Sector 0, also known as the \"manufacturer block\" (includes the 4 byte NUID \"serial number\").\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e13.56MHz Mifare S50 1k emulator chip\u003c\/li\u003e\n\u003cli\u003e4 byte NUID and all of sector 0 is writable\u003c\/li\u003e\n\u003cli\u003e10.25mm x 13.5mm x 0.65mm flexible biopolymer package\u003c\/li\u003e\n\u003cli\u003eWant an analog? \u003ca href=\"https:\/\/office.dngr.us\/s\/Cbx8pBpPQQj3Lgf\"\u003eCheck out the STL\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eAvailable as:\n\u003cul\u003e\n\u003cli\u003eZUID which supports both gen1a and gen2 (aka CUID) magic features.
