Every housing society in India has the same gate problem: a paper register, a guard who calls residents for verbal approval, and zero audit trail. VisitorPasses replaces all of that with a QR code printed on A4 paper. Visitors scan it to fill a form. Guards scan vehicle stickers for instant entry. Residents generate guest passes from their phone. The admin sees every entry, every vehicle, every pass — with no app to install and no hardware to buy.
