  • HOW DO SAFESCAN’S BILL COUNTERS WORK?

    Safescan offers automated bill counters to meet a range of needs, from making your end-of-day routine faster and error-free up through bill batching and counterfeit detection. How do they do it? Let’s take a look under the hood.

  • WHAT FEATURES DO TODAY’S BILL COUNTERS HAVE?

    At one end of the spectrum, you have counters that just tell you how many pieces of paper you’ve fed them—but a whole lot faster than you could have counted them by hand (and without miscounting). As you move up, you get to bill counters that automate more of the cash-counting process for you. For example, all the bill counters in Safescan’s 2200 and 2600 series come standard with an add function that lets you sum up the number of bills over multiple stacks, and with a batch function that speeds up till and bank deposit processing by pausing after a certain number of bills have been counted.

  • HOW DOES A BILL COUNTER COUNT BILLS ?

    When you place a stack of bills in the counter’s hopper, the bottom bill activates a feed-in roller. As the roller rotates, it feeds the bottom bill to a second roller rotating at a faster speed. Low-friction flanges on each side of this second roller make sure only one bill gets fed in at a time. Next, fanning wheels separate the bills before they pass by an optical sensor that tallies each one (and, depending on the machine’s features, its value). The counted bills then fall neatly into the output stacker on the front of the machine.

  • WHAT’S THE DIFFERENCE BETWEEN FRONT- AND BACK-LOADING MACHINES?

    In both systems, the hopper where you place bills to be counted is located on top of the machine. The difference is that in a front-loader, you place the stack of bills horizontally (flat); in a back-loader, you place the stack vertically (on its side). This difference is also what lets you keep adding bills to the stack as a front-loading machine runs, which can increase your processing speed if you have a lot of bills to count.

  • HOW DO BILL COUNTERS DETECT COUNTERFEIT BILLS?

    As the bill passes through the machine, a series of integrated sensors check one or more security features built into modern currencies. The simplest devices just check for the presence of UV marks; more advanced ones add magnetic and size checks. Top-of-the-line bill counters like the Safescan 2600 series are programmed to specifically recognize the unique size, ultraviolet, infrared, magnetic and holographic properties of each denomination for every supported currency.

  • HOW DOES WEIGHT-BASED BILL COUNTING WORK?

    You can also count bills by weight. High-precision money counting scales such as the Safescan 6165 and 6185 use finely calibrated load cells—devices that create an electrical signal whose magnitude is directly proportional to the force being measured—to weigh several bills at one time. The scale stores a detailed table of weights in its memory for every supported currency and denomination, which it uses to accurately calculate the number of items it is weighing. (See our page on counting money by weight if you’d like to know more about how the process works.)
