Instagram has yet another answer to Snapchat, but this time it's covering one of the basics: namely, adding friends. Months after it started testing, the social network has introduced "nametags" that make friend additions as simple as pointing your camera at a code, much like Snapcodes. Once you've created a nametag (complete with colors, emojis and selfies), your soon-to-be pal just has to launch the camera and hold down on the screen when the tag is in view. From there, they'll receive options to either follow straight away or view the profile. You can share nametags with others through text messages or other social platforms if you're trying to build as wide an audience as possible.
