Maker-Checker Gates: Stopping Staff Theft in Phone Servicing

How rogue employees swap genuine components for low-tier duplicates—and how supervisor approval thresholds block internal leakage.

The Vulnerability of Unmonitored Repair Tables

In high-volume repair shops, technicians handle valuable capital assets daily. The temptation to swap a customer’s genuine Apple display with a Grade-A duplicate, write off the authentic screen as "damaged," and sell the original privately is a major source of shrinkage.

Implementing Maker-Checker Approval Limits

iShopMaster eliminates employee collusion by implementing **Maker-Checker Security Gates**:

**Threshold Rules**: Any manual repair price reduction or diagnostic override exceeding Rs. 15,000 is instantly locked.
**Supervisor Checker**: The ticket requires a secondary signature and RBAC clearance from an authorized admin to commit.
**Serialized Validation**: Every replacement part is assigned to the technician’s active session, creating an airtight audit trail.
