Teaching is translation. A teacher must be able to “translate” his knowledge in such a way, so that it can be perceived and fully understood by his students. As an IT Consultant, that same procedure must take place between you and the computer as well. This is the very concept behind the current design. Personal information of the client is viewed both in a “human” language but also in binary code that writes his last name. In the same way the global machine language of the QR Code link would take you to the client’s personal facebook page providing you with his credentials, when scanned.
