Record both ends of the connection

A cable label is most useful when it explains where the connection goes, rather than repeating a connector shape that is already visible. A How To Geek article describes programming NFC stickers with the cable type and the devices attached at each end. Scanning a tag with a phone then reveals information that would be difficult to fit on a tiny handwritten label beneath a crowded desk.

Keep the tag readable

The source uses a phone app to write a text record to each sticker, then attaches the tag so its face remains relatively flat. Wrapping the sticker tightly around a narrow cable can interfere with scanning. The stored text can be reused as a starting point for similar labels and erased when a tag needs another purpose. This approach suits connections with several possible destinations, though it requires a compatible phone and a successful scan rather than an immediately visible printed name.
