The invention includes systems and methods for facilitating risk assessment for point of sale transactions utilizing at least one risk triggering value (RTV) stored within a distributed (e.g., local and/or regional) processing site. An RTV is a condensed version of a set of complex risk data and strategies usually found in central processing sites. The distributed site, after receiving a request for payment authorization, a risk value is calculated for the request. The distributed processing site compares the risk value to the RTV to determine whether to authorize payment. If the risk value is less than or equal to the RTV, the payment is authorized while a risk value greater than the RTV will not be authorized. After one or more authorizations, the distributed processing site forwards the information from the transaction(s) to the central site, wherein the central site calculates a new RTV for the account and distributes the new RTV to the distributed processing site.
