Contactless payment disabler

thingiverse

Helping people help themselves: because if you're too drunk to remember your own PIN code, you probably shouldn't have that next beer anyway. Concerned about security flaws with the contactless payment feature on new credit cards? Simply punching a hole in the right spot will do the trick. Just print and align this template to find the perfect spot. Reader beware: I won't take responsibility for damaged cards due to incorrect usage, lost cards, corporate greed, idiocy, Murphy's Law, global warming, or any other unforeseen circumstance. Stay happy! //EDIT (March 11)// Added a STL file and OpenSCAD source code for a printed tool Print Settings: Rafts: No Supports: No Resolution: 0.2 Infill: 50 Custom Section: With a bright light, you can sometimes see the conductive track loops forming the antenna coil. Cutting anywhere along this track disables the antenna. A 1 mm hole at the indicated spot is likely to produce the desired effect. This is how my card looks after a successful punch operation. Yes! The contact chip still works, but the wireless functionality is dead.
