We have an app called mobile pay in Denmark, which I guess is similar to Apple Pay in that you link a credit card and it lets you send money to friends or pay for stuff. It’s owned by our banks and it works most places a credit card wouldn’t, like in small stores that can’t really afford to have a credit card terminal. That’s it’s main uses, sending money to friends or buying things. Only they also have an API for the web, so you can now pay for things you buy in more and more online stores.
I use it a lot. It’s never been easier to collect expenses from board game nights, and when I recently bought the first Harry Potter book (in Danish for my daughter) I didn’t have to enter my credit card information.
I think that’s what Libre will be, only global. I don’t like Facebook, but if they actually succeed at this, they’ll become the easiest way to pay for things on a global scale.
