Automated Response Unit (ARU)

Posted on 09. Feb, 2009 by admin in Merchant Article

An ARU (also known as a voice authorization, capture and deposit) allows the manual keyed entry and subsequent authorization of a credit card over a cellular or land-line telephone. With this method a merchant typically imprints their customer’s card with an imprinter to create a customer receipt and merchant copy, then process the transaction instantaneously over the phone.

Payment gateway

A payment gateway is an e-commerce service that authorizes payments for e-businesses and online retailers. It is the equivalent of a physical POS (point-of-sale) terminal located in most retail outlets. A merchant account provider is typically a separate company from the payment gateway. Some merchant account providers have their own payment gateways but the majority of companies use 3rd party payment gateways. The gateway usually has 2 components: a) the virtual terminal that can allow for a merchant to securely login and key in credit card numbers or b) have the website’s shopping-cart connect to the gateway via an API to allow for real time processing from the merchant’s website.

Level 2 or Level 3 Processing - Purchasing Cards

Visa and Mastercard have created a specialized type of credit card used primarily by government agencies and businesses. Increasingly, corporations and government agencies are relying on this form of payment to compensate their service providers and suppliers. Businesses benefit by receiving their funds quickly and by winning competitive bids and government contracts where purchasing cards are the required form of payment. The downside, however, is the increased costs associated with receiving these payments. These costs will usually be much higher than accepting a standard consumer credit card.

The solution is that some businesses may qualify for ways to process these transactions that allow them to pay lower fees if they can supply additional information, called “level 2 or level 3 data”. For example, if government transactions are over $5,000, businesses can significantly reduce their transaction costs by including “level 2 or level 3 data” about the purchase along with each transaction. Examples of level 2 or level 3 data is a purchase order number associated with the transaction that the credit card will be paying. This data is passed on to the purchaser so that it may be many times easier to reconcile the transaction. If all the required data is not collected and passed on during the transaction, the merchant can have surcharges added to the basic fees or be forced into a non qualified transaction category.
