Abstract
Abstract Checks used to effectuate commercial and private transactions may be cleared through the banking system by transporting images of those checks between sending institutions and receiving institutions in forward and reverse flow paths between banks of first deposit and payor banks. The check images are transported through a public switched telephone network which contains a special check imaging node which provides a network based check clearing service for customers of telephone network. The check imaging node receives images of checks from institutions which subscribe to this service and routes those images through the telephone network to intended subscriber and non-subscriber recipients. Transmission of check images through a public switched telephone network may completely replace existing check clearance procedures or may be used in conjunction with existing procedures.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
116 words
A public switched telephone network, comprising: at least one check clearance services node which receives an image of a check from a check clearance service subscriber connected to the network and routes that image to a recipient connected to the network; a storage device for storing a plurality of check images received by the node; a database containing information relating to each of the subscribers to the services provided by the node and information about potential recipients of check images from the node; and a node controller which is responsive to information contained in the database for storing check images in the storage device and routing check images to recipients through the public switched telephone network.
