The recent police operation that managed to locate hidden cloning devices in ATMs has highlighted the need for advanced forensic techniques. The use of 3D scanning and photogrammetry allows for documenting the exact position of these skimmers with millimeter precision, preserving the original scene for laboratory analysis. This technology has become an essential tool for investigators.
Forensic documentation using point clouds 🔍
The process begins with a handheld laser scanner that captures the geometry of the ATM and its surroundings. The orientation of the hidden camera, the installation angle of the magnetic stripe reader, and any micro-perforations in the front panel are recorded. The resulting point cloud allows for measuring exact distances between the device and the card slot, as well as the installation height from the ground. Combining this data with high-resolution photographs generates a textured 3D model that reveals details such as glue residue or tool marks, impossible to appreciate with the naked eye.
Virtual reconstruction as irrefutable evidence ⚖️
The final three-dimensional model not only serves for technical analysis but also becomes a key piece during the judicial process. Jurors can virtually navigate the recreated scene, observing from the perspective of the victim or the criminal. This immersion eliminates ambiguities about the skimmer's location and clearly demonstrates how the cloning mechanism operated, facilitating the understanding of complex technical concepts for people without forensic training.
What specific 3D scanning methodology allows differentiating a cloning device attached to an ATM from the machine's original components during a field forensic inspection.
(PS: don't forget to calibrate the laser scanner before documenting the scene... or you might be modeling a ghost)
