  • Ruby SuperSystem®

    Convenience, Compatibility, and Control in an Affordable, Integrated POS Solution

    The VeriFone Ruby SuperSystem® combines card processing, fuel dispensing, dispenser card reader (DCR) control, and ECR functions to meet the needs of fast-paced petroleum/convenience-store operations—where quick customer turnaround, easy pump control, and accurate record keeping are imperative.

    The Ruby is compatible with a wide range of pumps, allowing you to bring it onto most sites without special accommodations. With easy-to-understand fuel icons and programmable PLU keys, the Ruby can simplify sales procedures and expedite service at all your locations. Its built-in training mode reduces the time and cost of bringing new employees up to speed. And its specialized reporting and tracking features help you better manage your business operations.

    Fuel Functionality: One System Fits All
    Because Ruby is pump independent, you can use it at virtually all your sites. It interfaces with major electronic dispensers and dispenser card readers — including Bennett, Dresser-Wayne, Gilbarco, and Tokheim/Schlumberger RPS.

    Better Control, Better Customer Service
    A single control point for fuel sales, Ruby supports both preset and prepay fuel sales. It electronically tracks up to 18 fueling positions on its standard icon display—or as many as 32 positions with an optional icon display. To authorize fueling and keep the traffic moving, your cashiers simply press a single key. And a quick glance verifies the status of one pump or every pump where money is due.

    Network and Payment Flexibility
    Ruby interfaces with a wide range of petroleum card networks, including those that communicate with independent oil companies. This lets you standardize operations for a variety of stations—whether they pump major or independent gasoline brands. And Ruby fully supports and speeds transactions for major oil-branded network cards and fleet fuel cards, as well as major credit and debit (ATM) cards. It also lets you accept a variety of other payment types, including cash, checks, coupons, and lotto tickets.

    Added Security
    Ruby keeps a running total of cash collected, alerting the cashier when it's time to make a safe drop. So there's never a surplus of currency in the cash drawer.

    Single-Key Price Lookup
    Price lookup is easier than ever. Ruby's unique pop-up menu keys link multiple PLUs to individual keys, placing more PLUs at the cashier's fingertips. And preset, pre-priced "hot" keys provide one-touch entry for your most popular items. Ruby also lets the cashier suspend, then resume, a transaction while the customer retrieves "one last item." In between, the cashier can process other sales, keeping the line moving and customers happy.

    Open Systems Architecture
    Ruby's software creates an open architecture environment, allowing Ruby to talk with a variety of back-office PCs and remote hosts. Communicating with your back-office systems, it quickly consolidates sales data into integrated management reports, producing a comprehensive summary of a station's activities. Ruby also allows you to download price and product changes and similar information. As a result, Ruby provides better control over operations and saves hours of paperwork. For managers, that means less time in the office and more time with customers.

    A Printer for all Reasons
    The Ruby includes the high-speed TMU-950 MultiStation Printer, which works with standard-width receipt paper. The TMU-950 can validate checks, print customer receipts or vouchers, and generate a variety of printed reports that help track the store's sales.
