Used-Device Trading Register

01

A guided counter buy in two to three minutes: device, checks, grade, photos, seller, price, signature

02

IMEI scanned or typed, with a live check-digit (Luhn) test that catches a typo before it is saved; dual-SIM and serial numbers too

03

The seller's ID read from a photo on our own servers, with no AI service involved; the number is stored encrypted and shown as its last four digits

04

A bilingual declaration of ownership, signed by the seller on the screen

05

A hold period you set (zero by default): until it ends, the till and the invoice refuse to sell that serial

06

Stolen-device alerts across your branches: every IMEI is checked against your own list and your whole register, and a match goes to the manager

07

The device passport: one timeline per IMEI showing when it was bought, graded, held, repaired, sold and under warranty

08

A daily report per branch at closing, and an export for the authorities, watermarked and logged, when they ask

09

Trade-in at the till: the old phone pays part of the new one, and the books balance

010

Data-wipe certificates, numbered and bilingual, with a QR code anyone can verify
