Point of Service (PoS) devices tend to serve their customers over long periods, therefore the need to support legacy technology becomes important.
Legacy cash register PoS applications were designed to handle RS-232 based bar code scanners and communicate with COM ports. This technology and these physical ports are quickly becoming obsolete and are being replaced by other forms of connectivity--most commonly by USB.
With millions of deployed PoS stations in the market, the substantial challenge for manufacturers is to reduce the cost and effort involved in upgrading. One way to achieve this is to minimize the replaced components. Because the new hosts do not support serial ports anymore, there is no alternative other than redesigning the device hardware to use USB. However, there is a way to remain with the original software packages, using suitable USB-to-Serial drivers.
DriverCore for point of service devices supports the specific USB connectivity needs of manufacturers of PoS bar code scanners, cash register printers, measurement equipment and secure money transaction PIN PAD devices.

DriverCore gives PoS peripheral OEMs an easy way to integrate new USB-based devices with legacy applications and provide full backwards compatibility with unique industry specifications and designs. This is achieved using a USB-to-Serial driver that exposes the USB device as a serial COM port to the operating system.
This approach allows continued use of the original application (designed to handle serial communication), thus eliminates the requirement for software updates and other related integration efforts.
