My physical cards dont work. Possibly wrong setup when writing data onto the stripe??

Your msr software should automatically add the symbols like % ; ?
and you must have = in track 2
but I have no experience with mcr200.
Why does your card # start with 0 ? Your track1 shown above looks incredibly long too. I would leave track 1 off. Just put "B" no quotes and thats it. Track 1 isn't needed at most places, depends on the store.
