According to this Daily Mail article, Go-Ahead, one of the largest train companies, is investing in facial recognition technology that it says could eliminate queuing for things such as tickets. The technology might also be used at airports, cash machines etc to cut queues while providing a high level of security.
The article goes on to describe another company which will use facial recognition technology to provide mobile apps which can take information from your social media profile and use that to identify your correct identity by scanning your facial details. One of the worries being is that the technology may be used to impersonate someone.
I must admit some of this goes over my head, but what do you think? Is this technology a good thing and could eliminate queuing forever, or could we be handing companies too much information about ourselves which can then be exploited by others all for a bit of convenience for ourselves?
