What can our computer system find?

STAMP’s state-of-the-art machine learning computer system examines complex halachic requirements the human eye might miss, and is operated by a top-knotch magiah who then reviews its findings.

We detect

Spelling errors
Tzuras ha’osios: Letter formation and halachic shape validation
Spacing issues: Identifying improper gaps between letters and words
Tagin: Disconnected, touching or faded crowns atop the letters.
Mixed writing styles: Ensuring ksav consistency
Forgery protection: By matching the 'hand writing' of every mezuzah to the certified sofer
Article traceability: Matching every product to a unique internal ID
Item recognition: As no two items are ever identical, scan your mezuzah to verify its certified status.
