Contactless payment disabler

thingiverse

Helping people help themselves: because if you are too drunk to remember your own pin code you probably shouldn't have that next beer anyway. Worried about security vulnerabilities with the contactless payment feature on new credit cards? Punching a hole at the right spot will do the trick. Just print and align this template to find the right spot. Reader beware: I will not take responisibillity for broken cards due to incorrect usage, lost cards, corporatocracy, idiocrity, murphy's law, global warming, force majeure in general and so on... Stay happy :) //EDIT (March 11)// Added a STL thing and the OpenSCAD source for a printed tool Print Settings Rafts: No Supports: No Resolution: 0.2 Infill: 50 Custom Section With a bright light it is sometimes possible to see the conductive track loops forming the antenna coil. A cut anywhere along this track disables the antenna. A 1 mm hole at the spot indicated is most likely to produce the desired effect. This is how my card looks after a successful operation punch. Yes! the contact chip still works but the wireless functionality is dead.
