You'd be surprised. People with a cheap chink thermal sensor can spy on people coming in and out using keypads. Corporate espionage through people holding the door open for others and other fairly low level attacks are still very, very effective today.

Tons of systems themselves may be secure in a perfect vacuum, but quickly fall apart when you start observing the environment it's in. For example consider a public-key based digital authentication electromagnetic lock. You'd think it'd be impossible to get in without a keycard. Yet a kid with a spool of copper wire and a nail can still walk in no trouble if they use a bit of creativity if the design in the wall was anything but perfect.
