Check guarantee services is a simple process at the point of sale. Your sales associate enters the customer’s driver’s license information into the point-of-sale credit card terminal and/or slides the check through a check reader to capture the bank account data. In less than one second, Commercial Merchant Services authorizes the check from its database of millions of records, accessing both local and national negative files of unpaid checks. With the guarantee service the authorized checks that bounce are reimbursed to you in full after we receive them. The verification service does not offer the risk-free assurance and reimbursement of guarantee yet still accesses the databases to give you another alternative.
