Swapping clipper cArds makes no sense as you typically have money stored on it.
In high school taking Bart during summer to Berkeley (cus I'm a nerd who took optional summer school at cal) I would clone my Bart cards. The magnetic stripe is redundant horizontally. Take one hard with a nickel on it and rub off its magnetic strip with an exacto knife. Take another with $20 on it, use the knife to cut its and the aligned 5c stripe in half, then swap and place a single scotch tape stripe in the back to affix them. Pop it in the machine, add 10cents, and out pops a new card with $20.10.
