QR Codes:
Companies are using QR code technology for many beneficial reasons. Some examples being directing customers to a landing page/website, sending a message or email,downloading apps, and directing customers to social media sites etc. A QR code is an input device because it is drawing in information from a site. One disadvantage to this technology is the dependability on a mobile device or smart phone. If a user does not have any of these devices, then the code is rendered useless to them. Another disadvantage of the QR code is the the lack of familiarity of the code with people. Though they are becoming more common, there are still many social groups who do not know enough information about this technology. The problem comes from different businesses using the QR code for advertisement reasons and not reaching a certain group of people who may be interested in the product they are advertising for.
