New: NFC Keyboard Emulator, tap a card and you're done
Turns a contactless PC/SC card reader into a keyboard. Place a card on the reader, and its UID appears in the focused field. For macOS and Windows.

You have an NFC reader like the ACR122U. You place a card on it, and nothing happens in your form. Many readers hand cards over through the PC/SC smartcard interface rather than acting as a keyboard. So a web form or a till that simply expects typed input never notices.
NFC Keyboard Emulator closes that gap. Pick your reader, switch typing on and place a card. The app reads the UID and types it into whichever field has focus, just as if you’d typed it yourself.
What it does
- Works with contactless PC/SC readers, verified with the ACS ACR122U.
- Output the way you need it. Upper or lower case, separator, byte order, prefix, and Enter or Tab afterwards if you like.
- No card in the wrong field by accident. Typing starts switched off, and one click turns it on or off.
- A log of every scan with time, reader and UID, exportable as CSV.
- Optionally send scans to your own server over HTTP or WebSocket. Until you switch that on, no UID leaves your computer.
