When buying or reselling a used phone, trust is often the biggest barrier. People worry about hidden defects, leftover data, or fake IMEI numbers. NSYS Certification removes this uncertainty by providing a verifiable, tamper-proof record of a device’s condition and identity.
Every certificate is linked to a single IMEI number, created the moment diagnostics are completed, and stored in the NSYS cloud with a cryptographic hash. Once issued, it cannot be changed or reused — ensuring complete transparency for both buyers and sellers.

What the Certificate Confirms
Verified Device Identity
The certificate shows the phone’s make, model, storage, OS version and IMEI — all retrieved directly from the hardware. This prevents mismatches, IMEI fake risks, or incorrect specs.
It also includes an IMEI blacklist check, so buyers don’t need to run a separate IMEI or phone lookup by IMEI before purchasing.
Clear, Detailed Diagnostics
NSYS automatically tests key components — display, touchscreen, cameras, audio, sensors, wireless modules, charging, battery health, biometrics, iCloud/Google lock and more.
All results are logged with timestamps, providing objective proof of what works and what doesn’t, instead of subjective grading or guesswork.
Reliable Battery Health
The certificate reports real battery capacity and cycle count, helping buyers understand the device’s remaining lifespan.
Documented and Compliant Data Erasure
NSYS erasure follows NIST SP 800-88, ADISA and GDPR requirements. The certificate logs the wipe method, timestamp and operator ID, giving businesses a complete audit trail and giving consumers peace of mind.
Tamper-Proof Verification
A unique QR code links to the live cloud record. Any attempt to modify the certificate invalidates the cryptographic hash — making tampering impossible to hide.
Why Certified Refurbished Devices Matter
Choosing a refurbished phone already reduces environmental impact:
– ~78 kg CO₂ saved per device
– ~77,000 L of water saved
– 80–90% lower carbon footprint vs a new phone
But sustainability only works when buyers trust what they’re getting. Certification provides that trust.
NSYS Certification makes every transaction clearer, safer and more reliable. For sellers, it proves professionalism and compliance. For buyers, it delivers confidence that the device’s identity, condition and data integrity have been independently verified — and that what’s written on the certificate matches the reality of the phone in hand.
