What are Opos Common Control Objects and how to use them
Opos Common Control Objects (CCOs) are a set of software components that provide a standard interface for point of sale (POS) devices such as printers, scanners, cash drawers, and so on. They are based on the OLE for Retail POS (OPOS) specification, which defines a common architecture for POS applications and devices.
Opos CCOs enable POS applications to communicate with different types of devices from different manufacturers without requiring device-specific drivers or programming. They also simplify device configuration and testing by providing common tools and utilities.
To use Opos CCOs, you need to install the following components on the computer where you plan to use the device:
Opos Common Control Objects, version 1.13 18. This is the latest release of the CCOs as of April 2023, and it supports all OPOS APIs from Release 1.01 through Release 1.14.1[^1^].
Opos service objects from device manufacturers. These are the software components that implement the OPOS APIs for specific devices. You can obtain them from the device vendors or their websites.
Visual C++ 2008 Redistributable Package. Some service objects require this package to run properly.
After installing these components, you need to install and configure the hardware device according to the manufacturer's instructions. You also need to associate the device with a hardware profile in Microsoft Dynamics AX for Retail POS, which is a POS application that uses Opos CCOs[^2^]. For more information, see Set up OPOS hardware devices.
Opos CCOs provide many benefits for POS developers and users, such as cross-device compatibility, performance optimization, and security compliance. To learn more about Opos CCOs and how to use them, you can visit the MCS: OPOS Common Control Objects - Current Version website[^1^], where you can also download the latest version of the CCOs and view their history and documentation.
One of the main features of Opos CCOs is that they are backward compatible with earlier releases, meaning that you can use the latest version of the CCOs with applications built against previous versions without requiring any modifications or rebuilds. This also means that you can use newer devices with older applications as long as the device supports the OPOS APIs that the application requires.
Another feature of Opos CCOs is that they support multiple device categories and models, such as barcode scanners, magnetic stripe readers, check scanners, biometric readers, and so on. You can use the same CCO interface for different devices within the same category, or even mix and match devices from different categories. For example, you can use a barcode scanner and a magnetic stripe reader with the same CCO interface.
Opos CCOs also provide security and compliance features for POS applications and devices. For instance, they support encryption and decryption of sensitive data, such as credit card numbers and personal identification numbers (PINs), using industry-standard algorithms and protocols. They also support PCI compliance, which is a set of security standards for payment card transactions. For more information, see Implementation Guide for PCI Compliance. 061ffe29dd
