Hi,
Just purchased 3 Sandisk Ultra 32GB class 10 cards for myself & 2 of my friends. The problem arised when my firend cut open the packing & kept all three cards together 
The packaging has the serial numbers for all three. Now we want to register our warranty but don’t know the which card is from which packaging, so the mix up has led to confusion. Is there a way I can read serial nos from all three memory cards.
I have a windows & a mac as well. The cards go into Canon 550d.
Looking forward to a quick solution.
Thanks already
