This is my entry into the back to school contest. This is so easy to perform and almost 100% un-detectable if done right.
Basically when you or the staff swipe the card the black tape blocks it from reading the magnetic strip on your card so it seems that its broken.
Step 1: Tool's
It really dosnt matter what card you
use so long as it has a black signature
strip on the back.
* Sharpener/E-xacto knife
Step 2: Choose Your Tape
or black tape, i would suggest black tape as it
has a less shiny finish to it, but still its your choice.
Step 3: Stick It !
Step 4: Slice It!
Step 5: Wash It!
Step 6: Use It!
Or giftcard mayhem !!!!!!!!!!!
