The Victorinox SwissCard is a flat tool about the size of a credit card, that fits easily in a wallet or pocket. It includes six detachable tools, with features similar to the Signature Swiss Army knife. The current SwissCard version was introduced in 2012 (it does not have rotating protractor/flap for the scissors, that was found on the original SwissCard). It's interesting that this new variation is marketed as the "SwissCard Classic", even though there was never a previous flapless version.
There are no similar tools from Leatherman or Wenger.
