I’ve heard of some kind of security system whereas you can enter either the usual password or a “special” one, and if you enter the latter you’re granted access but the police are alerted, or something like that.
The extension to that to an ATM might be one which gives fake bills, takes a picture, and alerts the police if the “fake” PIN is input.
For ATMs, the idea is out there, but it has never been implemented. Snopes on this:
The Credit Card Accountability Responsibility and Disclosure Act of 2009 compelled the Federal Trade Commission to provide an analysis of any technology, either then currently available or under development, which would allow a distressed ATM user to send an electronic alert to a law enforcement agency. The following statements were made in the FTC’s April 2010 report in response to that requirement:
FTC staff learned that emergency-PIN technologies have never been deployed at any ATMs.
The respondent banks reported that none of their ATMs currently have installed, or have ever had installed, an emergency-PIN system of any sort. The ATM manufacturer Diebold confirms that, to its knowledge, no ATMs have or have had an emergency-PIN system.
