But from now according to RBI guidline, if you fail to collect the cash, the ATM won’t (retract) eat it up. Instead, the money will remain at the mouth of the ATM, till the time the greens are collected. Which means, for some reason, if you forget to collect the cash (and this does happen), as soon as it is spitted out, someone else might be able to take it. Banks like HDFC Bank Ltd already have posted this notice on their website and ATM screens
The good thing is that you will not be at the mercy of a time-window to collect your the cash. The disadvantage of this sytem is that, you forget to pick the cash this would lead to loss. So, the next time you are at the ATM, be careful to take you dispened cash completely
