More and more people are using smartphones thanks to budget friendly mid-rangers, almost anyone can now afford to buy a smartphone.
Mobile payment is becoming more common and it is an opportunity to acquaint people more into using bitcoin . Mobile payment will eventually replace credit cards or at least will make them less mainstream. An example of this is Apple Pay. Bitcoin smartphone wallet apps are to use when you have a transaction, you just scan a qr code and the transaction is done though will take some time to be confirmed.
I definitely agree with you. There are more and more people making payments via their smartphones, I personally use google wallet and use my fingerprint to authorise payments. It is really simple and hassle-free. I personally don't use Bitcoin this way as it is more of an investment for me, but a lot of other do and it has surely had a large impact on the growth of Bitcoin.
