Some of the comments here are hilarious.

But as a snapchat user and friends with non-teens who use it a lot with their spouses/kids, I found this feature well executed.

Snapchat took its cue from Wechat finally, where this feature has done extremely well.

Square's move into this space is awesome to see as well. They are moving in Stripe's territory right after Apple Pay comes out. Interesting move.
