They managed to achieve this by using a high-tech 3D printer to make the skimmers for ATM machines look as real as possible, but why stop there? Not too long ago a member from a German lock-picking grop, Sportsfreunde Der Sperrtechnik, used a 3D printer to replicate a key to unlock handcuffs used by the Dutch police. Amazingly he managed to achieve this from a photo of the key hanging from the belt of the police officer, and through some basic math to gauge the size, he managed to produce a workable key, which he then put the model online for anyone to print it for themselves.
Granted this could be a quick and efficient way for regular folks like you and me to replicate house keys and what not, but considering it didn’t exactly seem like a complicated process to replicate a handcuff key based on a photo alone, who’s to stop criminals from replicating our car and house keys in the future?
