Point of sale transactions can be efficiently processed by use of a 
point of sale terminal having both 
image capture and storage capability, as well as other information input capabilities such as a MICR reader, a bar code reader, a keyboard, or similar 
input device. The 
system stores an image of the actual transaction documents, such as the bill to be paid and the check by which 
payment is made, for future reference and 
verification. In this way, paper copies of the bill need not be archived, and the check can be processed by electronic check conversion, further lowering costs. The 
electronic transaction information, such as biller identification, account number, 
payment made, and the like is forwarded from the POS location to a central 
data processing center in real time and 
authorization or denial of 
authorization to accept 
payment is returned to the POS terminal in real time. Additionally, 
system updates such as authorized billers, service fee schedules, and the like can be updated in real time, each time a transaction is transmitted from or to the POS terminal. Another advantageous feature is that a single POS terminal can be configured to communicate with multiple service providers and hence accommodate multiple different types of transactions such as issuing money orders, gift certificates, official checks, payroll checks, check cashing, bill paying, 
credit card authorization, age 
verification, and the like.
