When I bought my smart phone and saw all the apps which came with it at first I was a bit lost, but slowly, slowly I installed one after the other, I mean the very important one like Whatsapp.
But then I found out that I could buy train tickets via Smart phone and just show the bar code ! I will make it I thought and I made it without asking anybody and tried it out when I went to Brussels by train where I proudly showed my smartphone with the code and the poor controller had no code reader ! All the others around me were young people with their classical tickets and me the vintage lady had a bar code on my phone !
Next app which I thought I will make it was a payment. I had already installed my bank icon and could read immediately how much monery remained on the account. I tried and I made it ! Was I proud ! I payed my trip to the Christmas market in Düsseldorf by smartphone ! Now I know how it works. There are still some apps which I could use, but I have time ! One step after the other !
