Flipper Zero — copy the .nfc file to SD Card/nfc/ (e.g. via qFlipper), then open it from the NFC app and choose Emulate. Written for current firmware's NFC file format (Data format version 2, per-tag NTAG213/215/216 device type). If an older firmware refuses to load it, update via qFlipper.
Chameleon Ultra — the .bin file is a flat, page-by-page memory dump (4 bytes/page) of the same tag layout, the standard raw dump format used by Proxmark3/libnfc-style tools. In ChameleonUltraGUI: pick a slot, set its tag type to the matching NTAG21x, then use Load dump and select the file.
Each generated tag gets a fresh random 7-byte NXP-prefixed UID. The tag starts unprotected (no password) so any reader can read the URL immediately.
