ID cards are not going to fade away...
They are just boiling the frog more carefully these days. If they spend a lot of money on a big advertising campaign, they know they will stir up a lot of media and public attention and some of it would definitely be to speak out against the forceful introduction of ID cards. Whereas this way, they gently raise the temperature slowly creeping the ID card into being used in every walk of life via businesses that use it for this and that and before you know it you need it almost everywhere.
After all citizen, it may help in the perpetual war on terrorists.
They don't want us to think about the fact ID cards will allow far easier spying on whatever we do, because each time ID card approval is required the ID card system will then be able to record where and for what that approval was used for based on where the approval request comes from. (But then they are already able to spy on credit cards via a side effect of money laundering laws. But you don't give away your position after you for example buy tickets for something, (plus you could just use cash to buy some tickets), plus you can use these tickets whenever you like, whereas with an ID card that can do away with the tickets, they get real time monitoring of peoples activities each and every time ID card approval is requested.
I can see a time when we are required to use ID cards multiple times every day. For a start they can replace Oyster cards with ID cards. Then how about clocking in and out of work, automatically also recording your lunch time outside the office in the process. Then how about making parking meters use ID cards auto-deducting from your bank account. In fact thats a step towards all electronic money and therefore monitoring everything you buy. After all our ruling elite want a cut of every transaction, so they would love to finally kill off so called "cash in hand" style deals as well.
Plus just think about how much money they will earn from organizing and centralizing spying on all of us. Their rich friends in businesses would pay good money to get access to that data, so they too can profit from all the spying.
So much for our ancestors fighting against state interference. They could never have imagined how far that state interference would be able to go, but sadly George Orwell did.
