Interesting! Each time we get a batch of cards from a new supplier, we
test it in our product
(http://www.dovesystems.com/index.php?page=shop.flypage&product_id=56&category_id=097cd77791c8f09d2dd8cfd880c21d0e&option=com_phpshop)
to make sure it works! So far, they all have. Our storage requirements are
minimal, so we've been buing stuff in the 32M area. I've tested up to 1G
and everything has worked so far...
