I don't think that works - if I read the manual correct, badblocks writes
the same pattern to all blocks, it will not detect fake cards where multiple
blocks map to the same memory location.

You can use f3write / f3read. Those write files with known, non-repeating
patterns to fill the whole device (you need a filesystem for that), and then
verify them.
