the student answer that you will respond on 

Scan-as-you-go wallets I believe will be the future but along with the technology being used behind it. I believe that scannable wallets will need to use blockchain technology in order to have the highest level of security possible. The reasoning behind this is that when you are scanning things with your phone there can be "fake" codes to scan or scam links, etc. And this can lead to a breach in the security of a mobile device. Once the technology is fully there I do believe that there will be total mass adoption of digital wallets within the retail sector. The retail sector as a whole will most likely continue to struggle as it gets easier and easier to make transactions online. As our generation gets older we are so comfortable with technology that anything that allows use to use our phone we seem to adopt right away and use it seamlessly. The most difficult aspect about it would be implementing systems to accept digital wallets in every retail store.
