Usability

2D barcodes are intended to be an efficient and effective presentation mechanism on a mobile device. The adoption would be limited if the content being shown is not visible and usable on the handset.

To address this, content publishers need to create websites that are consistent with the dot.mobi domain standards. Further enhancement could be delivered using the principles adopted by the reader selection site. This website automatically detects the phone you are using in order to recommend a barcode reader. This same process could be used to filter the capabilities of the handset and present appropriate content.

A second consideration for usability is installing the reader onto the mobile phone. The process is relatively simple and not very technical. However, some users could struggle. If large scale adoption of 2D barcodes started to occur then mobile operators could offer an installation service for users who would otherwise struggle to install the reader themselves.
