Cool. Interesting, that I did not find this obvious work-around by myself. Maybe my brain refuses to take such ways of correcting one error by inserting another into account. Happy new year 200A to you all :-) Robert A. Rosenberg schrieb: At 23:34 +0100 on 01/08/2010, Bernd Oppolzer wrote

I had thought of that. I was concerned about what the non-problem cards would make of x'0a' when they were expecting a BCD year. Apparently this is just a problem with one family of cards -- the majority of cards in Europe and the world are apparently okay. What will they make of x'0a' when they

The machines can be fixed to temporally send a year of x'0A' in lieu of the x'10' which is being misinterprete Sort of. Considering that the card is usable on many Financial Institutions in many counmtriess, how do you co-ordinate the changes to machines that don't belong to you, and don't
