Cell Phone Repair Shop POS: 15-Digit IMEI Luhn Validation & Dead-on-Arrival Intake Checklists
Mobile Repair Counter SOPs • 7 Min Read • Updated 2026-11-14
Key Takeaway:When a smartphone arrives completely dead (no power) or liquid-damaged, secondary components like cameras, speakers, or Face ID cannot be tested upfront. Documenting power and corrosion status on the signed intake slip protects your shop from unfair blame.
1. Luhn-Verified IMEI Profiles & Masked Passcode Privacy
A single mistyped IMEI digit breaks warranty lookup later. ServisOS validates 15-digit GSM IMEIs using the Luhn checksum algorithm while masking customer passcodes (`123456` -> `12***6`) on printed customer copies.
- Flags Dead-on-Arrival (`powersOn: false`) and Liquid Indicator (`waterDamage: true`) risks clearly.
- Includes a built-in 30-day unclaimed device storage clause.
- Tracks digital `5x Hydrogel / Port Clean = 1 Free` loyalty stamps per device.
Shop Counter Checklist:
- Verify the 15-digit IMEI from the SIM tray or *#06# screen at check-in.
- Record SIM cards, cases, chargers, and pre-existing frame dents before bench handoff.
- Send a 1-tap WhatsApp diagnostic quote and wait for written `APPROVE` before installing costly parts.
