# How Does a POV Work in Blerify?

1. **Verification Request:**
   * When a user presents a digital credential (e.g., a mobile driver's license), the POV requests verification of the credential.
2. **Credential Validation:**
   * The POV verifies:
     * The **cryptographic signature** of the credential to ensure it has not been altered.
     * The **legitimacy of the issuer** (i.e., whether the credential was issued by a trusted entity).
     * The **status of the credential** (whether it has been revoked or not).
3. **Verification Response:**
   * The POV returns a result indicating whether the credential is valid or not, along with any additional information the organization may need.
