Automated Response Unit (ARU)
Many merchants want the ability to accept credit cards from anywhere at any time, but do not want to have to bring a credit card machine with them. United Payment Services offers Automated Response Unit (ARU) payment processing to eliminate the need for a physical terminal by allowing merchants to call an 800 number from any phone (cell phone, pay phone, landline, etc.).
ARU is designed for merchants who wish to accept transactions without having to buy or lease any processing equipment. ARU can be utilized by any size business, but is usually employed by smaller merchants with fewer transactions.
