he promised it would simplify the way people pay for goods and services,
Cash is still the simplest way to pay for anything and it keeps your purchases along with where and when you shop being no one's business but your own along with reducing being inundated with unwanted annoying pop-up web advertisements.
I have a problem understanding why people want to give up all their privacy, not only in their financial transactions but also in their personal life..e.g. facebook, twitter, instagram, etc etc.... where they feel compelled to broadcast to the world every time they manage to scratch their left buttock with their right hand along with the need to include a selfy to prove that they have done so.
Maybe I am old fashioned... preferring to enjoy my personal privacy, but I find that these toys have led to the dumbing down of people.... leaving me to scratch my head in wonder when in the cereal isle of the supermarket observing someone on their smartphone calling to find out which box of cornflakes to purchase.
Yes... I do have plastic... one of each... to use for on-line and telephone purchases along with "pay-at-the-pump" for gasoline and use checks to pay bills received in the mail/post...
