When the industry prepared for the Year 2000, I was working in a consulting company living good from doing reviews on Y2k-projects. Then the year 2000 came and nothing happened (besides a big party).
Then year 2010 came â€“ and the bug actually got hold of us. Initially I thought that I was reading a joke but it seems to be true. The German Sparkassen (a banking brand) had a problem with their ATM cards: The Gemalto chip on the card was unable to process the year correctly and failed to give you money.
I do not know how you handle your daily money consumption but here in Switzerland you are able to pay almost everywhere with your debit (say ATM) card. So, the cash I have with me is very limited and I run into a serious problem if I cannot pay with plastic. Additionally to get to money â€“ you need the card again. And finally I often rely on the fact that I can get local currency in a lot of countries with my debit card.
This really causes some serious troubles and â€“ at the end of the day â€“ affects the critical infrastructure of a country â€“ all of a sudden and without pre-warning.
