There are a lot of ways to share who you are as a person. Facebook being one of the most prominent but things like Pinterest or Deviant Art can help express yourself or tools such as Instagram can help store the memories great events you've been too.
Blippar have took that a step further bringing the "share" functionality directly to the person. Using facial recognition your able to share information with people.
This is definitely a useful way to build a personal brand, especially for those that are constantly in the public eye but it does have a few security concerns. Luckily the program is opt in so no one will have your information until you upload it yourself. This is an important fact to remember when you see people walking around the streets and pointing their phones at you... or they could just be still playing Pokemon Go.
Blippar's technology is certainly impressive. But in an era where our every move is watched over by CCTV cameras, the idea of smartphone lenses examining our faces wherever we go may not get the warmest of welcomes.
