ATMs soon to defend themselves from robbers

ATMs (Automated Teller Machines) are soon to be armed with a mechanism that sprays hot foam of chemicals in the face of the attacker or robber who is trying to open it  unauthorizedly.

Researchers of ETH University at Zurich are currently working on this and they've developed a film that will react when it is damaged. Two films with different chemicals are placed on top of each other and when they are damaged or subjected to an impact, the layers between them gets destroyed and the chemicals mixes. This triggers a reaction that produces oxygen, heat and water  vapor  foam with high temperatures reaching 80 degrees.

Wendelin Jan Stark, a professor at ETH's department of chemistry and applied biosciences said that this is less expensive and can be applied to all ATMs. He said that this mechanism spray the robbers and existing banknotes, so that it will make the cash useless even after it if robbed and it can even be traced.

This new tech is very useful as the number of ATM attacks are increasing quite fast these years. This is not only suitable for ATMs but also for things like cash transportation vehicles and all.
