Never miss a stamp, even without WiFi.
Your staff app works perfectly without internet. Stamps and points are recorded locally and sync automatically when connection returns. Perfect for busy periods or locations with spotty WiFi.
No credit card required · Offline mode on all plans
Stamp cards that never go down
Three steps. Zero internet required. The staff app handles everything locally and syncs silently when it can, so you never have to think about connectivity again.
Customer visits as normal
Staff open the Stampet staff app and scan the customer's QR code. The app processes stamps and points locally, with an experience identical to being online.
Transactions stored locally
Every stamp, redemption, and points transaction is saved securely to the device. Staff see a queued count, a clear indicator that everything is captured.
Auto-sync on reconnect
The moment the device finds connectivity via WiFi, 4G, or 5G, all queued transactions upload silently in the background. Nothing is required from staff.
Without offline support
With Stampet offline mode
Why offline matters more than you think
Internet outages are unpredictable. Busy periods strain routers. Your loyalty programme should be the one thing in your business that never lets you down.
No single point of failure
Your loyalty programme doesn't depend on your router, your ISP, or anyone's server being up. It runs on the device.
Busy period proof
During your busiest moments, whether queues, outdoor events, or packed markets, the system never slows down or goes dark.
On-device storage
Transactions are written to the device immediately. There is zero delay between scanning and recording, whether offline or not.
Silent background sync
Sync happens automatically when connection returns. Staff never need to upload, export, or reconcile anything manually.
Instant stamp confirmation
Staff see the stamp applied immediately on screen. There is no spinner, no loading state, no waiting for a server response.
Tamper-proof queue
Queued transactions are secured on-device. They cannot be modified, duplicated, or lost between scan and sync.
The Stampet staff app works exactly the same whether you're in a city centre or in the middle of a field at a summer festival.
Built for how local businesses actually operate
A mobile food truck operates at festivals with unreliable connectivity all summer. Crowds, remote fields, and temporary power make WiFi wishful thinking.
With offline mode, they stamp loyalty cards all day without thinking about signal. When they drive back into range at the end of the weekend, hundreds of transactions sync in seconds. Not one stamp is missed.
