When the opportunity cost of time is high, data input into an accounting program from printed receipts and invoices can be tedious and subject to error, especially when long alphanumeric strings are involved. Alternative methods are offered by technologies like optical character recognition (OCR) and barcodes. This article examines the context of the problem and explores creative open source methods of data input, including reading a printed receipt using OCR methods and using encryption and decryption of QR codes. Finally, the article uses PHP to extract the results and format a prototypical XML output file.
