The company's antiskimming system is invisible from the outside, but detects the presence of skimming devices near the card entry slot and alerts the bank without disrupting the transaction.
As the technology is new, Monaco said he couldn't disclose how many banks use their system.
But as banks ramp up their security measures, he and others recommend that customers do what they can to secure their transactions.
1. Be aware of your surroundings. Be extra careful of machines in dark areas or in places that don't look well guarded and monitored.
2. Pay attention to the front of machines. If it looks different from others in the area (for example, it has an extra mirror on the face), has sticky residue on it (potentially from a device attached to it) or extra signage, use a different machine and notify bank management with your concerns.
3. Notice how it feels to type in your PIN code. If it's difficult to punch the keys or you feel resistance, it could mean that a keypad overlay is present.
4. Cover your hand as you type in your PIN. If a camera is present or someone is trying to look over your shoulder, this will obstruct their view.
5. If you think the area around the card entry slot looks peculiar, pull on it. If it comes off or loosens, alert bank management but try to leave the machine as you found it. Leaving the evidence in place could help authorities track down the criminals.
6. If you find a skimming device, in addition to notifying bank management, the ATMIA says to notify local law enforcement.
