M-A-D Tag

M·A·D Tag writes NFC chips for the M·A·D Box. You configure on your phone what the M·A·D Box should type on your PC—keyboard shortcuts, text, passwords, or codes—hold an NFC chip against your phone, and you're done. When you later place the chip on the M·A·D Box, it reads it and types everything.

The M·A·D Box is the device for the app: It reads the chips and functions like a keyboard on your PC. Even without the M·A·D Box, you can use the app to write, read, and erase NFC chips (NTAG213, NTAG215, NTAG216).

Quickly load onto the chip

PassPort

• Your logins with page, username, password, and notes, protected with PIN
