Scanning Tax Documents with QR Codes
On printed annual tax documents, issuers add two-dimensional bar codes known as QR Codes which contain the tax document data in FDX JSON format. The QR code is placed in available space below the form or on a separate sheet included with the tax form. See the example below and also information for developers.
Tax software smart phone apps scan the QR code and import the data into the tax return of the user.
