Direct vs. Indirect Encoding, What's the Difference?
By Joe Barber, Chief QR Officer at the CodeZQR division of Computer Output Print & Internet (COPI)
I frequently get asked about direct encoding vs. indirect encoding, what is the difference and why should anyone care.
Direct Encoding is the process of encoding target data such as text, or a URL or an SMS message directly into a QR Code. Indirect Encoding on the other hand is the process of linking target information such as a URL to an index that is stored on a server and encoding the index in the QR code. A recipient that scans the code is then sent to the server which redirects them to the appropriate target.
The short answer is that Direct Encoding is the only practical way to go if you truly want to create a personalized dialogue with the recipient in your one-to-one communications such as transpromo or direct mail.
While there are some one-to-many marketing applications where indirect encoding might make sense, there are still a lot of uncertainties around patent issues with various indirect processes that have yet to be settled by the courts. Several companies have patents issued or pending in this area and it is unclear as to which if any patents are applicable, and if so where.
Unlike many other QR solutions which are strictly Indirect Encoding solutions, CodeZ QR allows you to do either. We allow you to encode any kind of data you desire, whether that is a direct URL, direct SMS, or an indirect index. We never dictate your method of communication with your client but rather leave that up to you and your needs.
