How Engineering Verification Works

Every product listed on Ayubaba undergoes the same rigorous process, carried out by a qualified electronics engineer — not an algorithm, not a tick-box exercise.

Step 1

Physical Engineering Assessment

Each product is assessed hands-on by a trained engineer using calibrated diagnostic tools. Condition, functionality, provenance, and safety. Nothing assumed from listed specs — every check is independently conducted.

Condition grading against standardised criteria
Functional testing of all key features
Wi-Fi and connectivity verification
IMEI check vs. National Stolen Property Database
Physical safety and structural integrity
Water damage indicator inspection

Step 2

Verification Record Generation

Assessment results are logged into the Ayubaba Verification System (EVS). A unique EVS ID is generated and a tamper-proof PDF Verification Record is created — including pass/fail/advisory results, engineer notes, and provenance documentation.
