Verification Standards

How CardProof establishes and preserves verification integrity

Introduction

CardProof Verification Standards define the requirements and best practices for creating high-quality proof-of-possession records. Following these standards ensures your proofs are trustworthy and useful for their intended purpose. These standards apply to all proof records created through the CardProof platform.

Verification Code Requirements

The verification code is a critical element of every proof record. It establishes the temporal link between your possession of the item and the proof creation.

Photo Requirements

High-quality photos are essential for creating trustworthy proof records. Each capture type has specific requirements.

Timing Requirements

The 90-second capture window is a core security feature of CardProof verification.

Trust Levels

Trust Levels (L1-L3) indicate how thoroughly a user's identity has been verified. Higher levels provide greater assurance of the holder's identity.

Proof Freshness

Proof Freshness indicates how recently a proof was created and its relevance for demonstrating current possession.

Limitations of Proof Records

Understanding what CardProof proofs do and do not prove is essential.
