Description

From the listing uploaded by “appupdater”.

The main purpose of this App is to help quickly validate the authenticity of documents. You can use it with any document containing the following: - a QR Code (a square barcode), and - text or URL, instructing use of this App to validate. Simply scan the document code with this App and get instant validation result. Documents could be certificates, transcripts, IDs, pay stubs, account statements, permits etc. You can use the App with both the original document, photocopy or a soft copy. Features: Instant: Validate in seconds! No need to figure out how to validate documents issued by an organization, contact them or sign-up for an account. You just need this App. Secure: The QR Code is digitally signed and tamper-proof. Any modification, invalidates the entire code. No network connectivity required for primary information: Since all the primary information is securely encoded within the code, no network connectivity is required to validate. Code Attachments will require connectivity but the security envelope is always maintained. Privacy: The verification of the code is done entirely within the App - no outside servers can track which documents are validated.
