My new job gave me recently a card for buying everyday lunch.
It also has an app, so you can pay with the "credit" card or with the app.
But I found most of the restaurant prefer the use of the card instead of the app.
What made me think how hard it will be to convert to bitcoin. If it's so hard for them to accept money virtually from an app, it will be even harder when it comes to bitcoin.
It isn't hard. There are ATMs that can do that, exchanged can accept Bitcoin and so on. It's not hard at all but it's rather unpopular, so not many people are able to use it. And because it's hard to be used for now, many don't want to include it in their businesses.
