This program generates QR codes in ASCII art or Sixel format for text terminals, e.g., console, xterm (with -ti 340 option to enable Sixel), mlterm, Windows command prompt and so on.

You can transfer data to smartphones with a QR code reader application from your terminal.

qrc program takes a text from command-line argument or standard input (if no command-line argument) and encodes it to a QR code.
