Working prototype

Development journey

One membership, everyone’s fair share.

A shared rewards balance tells an account how many points exist, but not who earned them or why the number differs from the receipts people remember saving. Platinum Points turns those receipts into an accountable, searchable ledger without pretending incomplete records are complete.

01 / Product principle

Evidence before certainty

OCR accelerates capture, but every field is reviewed before it changes the ledger.

02 / Product principle

Shared account, personal accountability

The membership remains shared while each receipt is assigned to the person who earned it.

03 / Product principle

Missing is a valid state

Unknown balances, approximate dates and unrecorded points stay visible instead of being guessed.

Product surfaces
