Batch ID, production date, metal type, weight, and purity recorded in our certified ledger.
Complete provenance trail from raw material intake through refining to final certification.
Confirm whether the certificate is genuine, unmodified, and traceable to a specific batch.
Certificate Authentication
How to verify your certificate
Every Welfinz certificate is engineered with layered authentication features. Follow these four steps to confirm that the certificate in your possession is genuine and unmodified.
Every Welfinz certificate carries a QR code in the lower-right corner for instant verification.
Use your phone camera or a QR reader app to open the verification URL on Welfinz servers.
Confirm the batch ID, purity, and weight match exactly what is printed on your certificate.
Hold the certificate to light to inspect the embedded WELFINZ security watermark pattern.
Physical Authentication
Detecting tampered products
Beyond ledger verification, physical authentication remains critical. Inspect every bar and certificate for the following signs of tampering before accepting delivery or transacting.
Genuine Welfinz bars carry a laser-engraved serial number. Check for uniform depth, clean edges, and absence of tool marks around the engraving.
All bars are sealed in tamper-evident packaging. Any signs of resealing, adhesive residue, or foil tearing indicate the packaging has been opened.
The certificate batch ID must match the bar serial number exactly. Mismatches, faded print, or altered fonts are red flags.
