Computerworld published an article describing a tiny device that can wirelessly hack point of sale and other magnetic-stripe based systems by sending malicious keyboard commands using a design vulnerability in those systems. Apparently a hotel room lock could be hacked within 18-30 minutes using the device.
The device was inspired by “MagSpoof” which is a device that can store magnetic stripe contents, wireless emulate a magnetic stripe read at point-of-sale terminals and even disable chip-and-pin transactions. The device generates an electromagnetic field that tricks the card reader.
