Alarm maker uses radiation to nuke ATM card skimmers

ADT harnesses electromagnetic pulses to protect ATMs, customers from having data stolen

By  

Cards embedded with smart chips to enforce PCI or ENV security and encryption can limit the losses somewhat, but are not widespread enough to address it all.

ADT Business Solutions just came out with a way to use an atmospheric affect best known for arriving immediately after a nuclear explosion to stop skimmers in their tracks.

The device is installed on or near the ATMs, rather than on the cards to make it easier for ATMs to defend themselves against skimmers.

Once installed, the device emits electromagnetic pulses (EMP) – waves of electromagnetic energy that is thick around the back of CRT-based TVs or computer monitors, energy that creates static on nearby radio stations and which follows nuclear explosions with bursts of electromagnetism strong enough to permanently destroy electronics.

The EMP generators ADT wants to build into ATMs aren't anywhere near that level of lethality. Instead they create static that makes it impossible for any magnetic-card reader to operate except the one that's in the machine itself.

"By placing the device in close proximity to the ATMs' factory card reader, it can block the operation of another card reader placed nearby without affecting the ATM," according to John Pearce, director of marketing with ADT Business Solutions. 

The EMP devices have to be calibrated to allow the ATM's reader to work while stopping any others from working by soaking them with static.

Kits to build the EMP units into ATMs cost about $2,000 per ATM, though the average $50,000 loss per skimming incident should cost-justify the added security, Pearce said.

About 150 have been deployed so far according to Security Management, though no banks have yet admitted installing one.

No word from ADT yet whether there's a more powerful version that could also burn out the engine in a pickup truck before it pulls the ATM from the wall. I'm sure something like it is on the way, though.
