Accurately capturing data from paper forms can be extremely challenging. Re-keyed-paper-based-form data not only is human-intensive, it’s also error-prone. Optical Character Recognition (OCR) can help reduce the amount of human involvement. However, it still requires some human supervision to ensure the data capture process is done correctly.
QR Code has been proven to streamline manual processes and improve efficiency. A QR Code can be embedded in the paper-based form. It would encode all the information that a user enters when the form is filled. The recipient would simply capture the documents via a traditional scanner or a camera and save as a PDF file. The QR code enclosed within the PDF file can be decoded to reveal the complete user-supplied data on the form. QR Codes are generated with error correction. So, as long as the QR codes are clearly captured, a near 100% accuracy in form-based data capture is achievable.
In this article, we will explore how the industry’s best barcode SDK decodes a QR code in different types of PDFs.
