The fastest way to kill a floor rollout is to make the app feel like extra work for the people already doing the hardest work. The floor app is built the other way round: it saves the karigar time on the thing they care about most — getting paid correctly.
Runs on any Android phone
No special hardware. The app runs in Gujarati, Hindi, English, Hebrew and Russian, so the floor reads it in the language they think in.
Two taps to scan a lot
Issue and receive are a scan and a confirm. Because wages compute from the very same record, entering a lot correctly is in the karigar's own interest — adoption tends to enforce itself.
Roll out floor by floor
Start with one department, let word spread, then expand. Karigars who see their wages settle cleanly become the best advocates for the next floor.
