About the NFC Lock Signal Waves black outline icon
A closed padlock with a tall rounded shackle carries three nested signal arcs and a solid dot on its body, the standard mark for a contactless radio connection. Together they mean protected wireless access. Use it for NFC and tap to pay flows, smart lock and hotel key apps, access control panels, digital wallet settings and security feature lists.
The waves are centered low in the lock body so the shackle stays clear and the whole shape still reads as a padlock in a list row. It pairs with key, fingerprint and shield icons in the library. Below 24 px, drop the outermost arc rather than shrinking all three.
This is the black outline version of the nfc lock signal waves icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
