Check verification service

A check verification service is a business whose primary work can be defined as essentially maintaining two relational databases: one of personal identities, and the other of bounced checks. They offer their services on a subscription basis to retailers and financial institutions, and their functionality is usually accessed either by telephone or internet. Some banks bundle a level of this service with a business checking account or with a bankcard acceptance program. Trade names this service is offered under in the U.S. include Telecredit, ChexSystems, and Verified.
