Wi-Fi

Some smartphones have the ability to connect to Wi-Fi by scanning a QR code. You can use the qrencode tool to do this.

Here's the standard template:

WIFI:S:<ssid>;T:<security-type>;P:<password>;;

Here's a couple of examples using qrencode, which you'll need to install.

# Example (print the output on the terminal):
qrencode --type=ansiutf8 "WIFI:S:<ssid>;T:WPA;P:<password>;;"

# Example (print the output to a file, which you can then print):
qrencode \
    --type=PNG \
    --size=6 \
    --foreground="4caf50" \
    --background="FFFFFF" \
    --output ppn5.png \
    "WIFI:S:PPN5;T:WPA;P:Groggily*Exclude1*Sublevel*Denial;;"
