A check guarantee card is a useful tool for protecting against bounced checks and ensuring payment for goods and services. Some synonyms for a check guarantee card might include a check verification service, a check assurance program, or a check protection plan. These terms all describe methods for guaranteeing that a check will be honored, either through the use of a third-party service or through an agreement with the issuing bank. Other similar terms might include check cashing assurance or check acceptance guarantee. Whatever the terminology used, the goal is ultimately the same: to provide additional assurances to merchants and other sellers that they will receive payment for the goods or services they provide.
