There used to be 2 types , Type l and Type ll. Type ll was thicker but it is no longer made. This is an improvement in design and adds to the CF versatility.
You may have upgraded the memory in your digital camera with a new CF card. They are easily found at drug stores, camera shops even Walmart now a days. CF cards were developed by SanDisk in 1994.
No doubt they helped to minitarize and make moble many devices. Now another newer memory type is the flash stick which is great for quick downloads of files from a pc.
