But why using a still "standard" plastic card? The movement is to e.g. smartphone as the one and only device always taken with us.. and all these described functions imho are much more simpler on a smartphone... Especially last example with the code to enter.... magnetic strip is still in use in the U.S. - I know - but since years it is no longer used in Europe. And can that "card" transfer the number also to the EMV chip? I am not sure.
