The Y2010 bug

[andrewducker]

Next time someone says that the Y2K bug was a load of rubbish, point them at this example of what happens when people don't test their software/hardware before rolling over a minor date change.

It's hit more than German cards. I seem to recall the Aussies got bitten too, as well as some US mobile networks (SMS datestamps IIRC) and things such as anti-virus updates and spam filters from some software companies.

Opinion seems to be it's likely down to code writing 10 into what it thinks is a decimal field when it's actually hex and the system thinking it's 2016. Thus the banks thought it was 2016 and therefore the bank cards had already expired and were rejected.

How does the change from 2009 to 2010 make them fall over, given they're already on 4-figure years to handle the change to 2000?
