I've shown you before how dangerous ATM skimmers can be - click here if you need a reminder.
Clever thieves put a skimmer over the card reader on an ATM where it snags your account data when you swipe your card. Oh yeah, and a small camera over the ATM keypad records your PIN when you punch it in, too.
Spotting a skimmer is hard, but scientists are looking to an unexpected animal to help catch ATM criminals: the bombardier beetle.
Scientists at ETH Zurich University found a way to replicate the beetle's natural defense mechanism - spraying a gas on predators that can burn their skin - and wants to put that technology inside ATMs.
Don't worry, the chemical the scientists use for the ATM model won't burn your skin. Instead, when an ATM is tampered with, it will "ooze hot foam" consisting of hydrogen peroxide and manganese dioxide.
On top of an oozing ATM, the security system will also dye any stolen money with nano particles to help law enforcement track the cash.
What do you think about this development? Are there better ways to keep ATMs safe? Let me know my posting in the comments below.
