On the chip and the stitching
A hand-stitched leather strap
that pays at the terminal.
Tap to pay with the watch you already own
A certified payment chip is sewn into the leather between the lugs and the buckle. No new watch, no case, no sticker — the watch looks exactly as it did.
Never needs charging
The chip draws its power from the terminal itself. Invis watch straps do not require charging at any point, so the strap behaves like leather and nothing else.
Set up in minutes
Download the Fidesmo App, hold the strap against the back of your phone and tap Connect. Your card is on the strap in a few minutes, with no store visit and no extra hardware.
Your watch stays. Invis Strap pays.
A certified payment chip is sewn into the leather between the lugs and the buckle. Pair a bank card once in the Fidesmo app, then tap the strap on any contactless terminal. Invis watch straps do not require charging at any point.
