Credit Card Security and Gas Pumps

How responsible should petrol stations be for how customers’ credit card information is collected & used? One would think, highly responsible. After all, it is their pumps into which customer insert their credit cards. If station owners fail to secure those pumps and crooks are able to install “skimmers” that collect card information, then I think the onus must be on said owners to demonstrate how it is that they are taking reasonable care. This Florida case, with more than 100 customers having been defrauded, raises some very interesting liability and security issues.
