About Barcodes

What are these code images you see popping up these days?  These are visual hyperlinks that can be used in ways similar to links you see in an email or web page.  They can connect the smartphone to a web page, email address or contact file, convey appointment details, generate a text message, display plain text, or several other more specialized uses.  If you are interested in seeing how they are created and making your own, visit this site.  It also addresses app standards compliance and makes this recommendation: "This generator follows established standards strictly and no scanner (yes, none of them) for any platform except Qrafter and Qrafter Pro for iPhone and iPad follows those standards completely."  Our testing confirms this, as popular apps like RedLaser produced inaccurate results.

For Android, we recommend the Barcode Scanner app.
