The Process
How TAJDEED certifies a phone.
A fixed, auditable process from diagnostic to certificate. Every step is logged. Nothing is negotiable.
Step by step
From drop-off
to certified device.
Bring it to a certified shop
Only TAJDEED-approved partners have the diagnostic tools and trained technicians to run a valid certification. The shop submits the device for a full audit.
The device is logged into our system under its serial number. No data is modified — only recorded.
60+ technical tests are run
Every test category is checked: display, cameras, battery, sensors, connectivity, software, and cosmetic condition. Each result is logged against the device's serial number.
Tests run in a fixed protocol and cannot be skipped. The technician cannot influence individual test outcomes.
The system assigns a grade
Based solely on the diagnostic data, the system assigns Gold, Silver, or Bronze. The technician does not choose the grade.
Gold requires ≥85% battery and all 60+ tests passed. Silver requires ≥70% battery and all critical tests passed. Bronze requires ≥60% battery and all essential tests passed.
Certificate is published
A unique certificate ID and QR code are issued immediately. The certificate is publicly accessible — anyone can verify it by ID or by scanning the code.
The certificate is immutable. Once issued, it cannot be modified, and any tampering is detectable.
You buy with full clarity
Before any money changes hands, you can see every test result, the assigned grade, and the exact warranty terms on the certificate.
The warranty runs from the date of purchase, not the certification date, and is valid at any TAJDEED-authorized repair shop nationwide.
