What you will learn
• What is WEPOS?
• WEPOS vs. XP Embedded
• What is POS for .NET?

What is WEPOS?
• Windows Embedded for Point of Service• XP Embedded leads to different vendors producing
different devices and custom images• Great flexibility for embedded systems• POS configuration challenges
• WEPOS offers a standard platform for the retail industry and more…• UPOS/OPOS Support – Allows ISVs to write
one application for hardware• Offers access to upcoming technologies such as RFID
and Biometric scanners• Provides integration to Enterprise solutions• Legacy support provides the best in
Total Cost of Ownership (TCO)
What is WEPOS?
• Microsoft’s recommended OS for full-featured Point of Service terminals• Point of Sale, Kiosks, Self-Checkout/Checkin, Fuel Pumps,
Automated Teller Machines, Security Terminals, etc.
• First in a series of Microsoft retail-focused investments that will continue through Windows Vista• Two parts: WEPOS and POS for .NET
What is WEPOS?
• Standard, retail-optimised OS platform for Point of Service devices• Only POS platform to provide Plug-n-Play support
for retail peripherals
• Based on Windows XP with Service Pack 2
• Provides an Windows XP Pro-like setup
• Reduced OS footprint
• Extend PC management to POS• Support for standard PC management technologies
(SMS, SUS)

WEPOS Installation Options
• Custom themes, logon screens, splash screens
• Changes through standard Window applets and tools, or custom VBscripts• Custom Shells – registry keys
• Customer Security
• Logon / Splash screens
Customization
• SDK to develop POS Applications and service objects in .NET • Run time for WEPOS and Windows XP Professional
• Supports .NET Framework 1.1 & 2.0
• POS for .NET 1.1 supports UPOS v1.9
• Abstract POS hardware from the software
• Standardise on a logic device name
• Change a device without having to recode the application
• Plug & Play is at the heart of POS for .NET
What is POS for .NET?
• SDK install from WEPOS CD, or web download
• Includes support to develop and test applications on XP Pro SP2 or WEPOS• Not supported on XP Embedded
• Documentation for .NET Classes and Management tools
• Sample code for service objects and applications
• POS Device Management command line tools – remote or local management

POS for .NET vs. UPOS
• PosExplorer replaces Control Objects• Eliminates CO/SO mismatches• PnP - DeviceAdded/Removed events• Device discovery and instantiation• Integrated with management
• Logical device names, default devices, enable/disable devices
• Small deviations from UPOS to adhere to the .NET design guidelines• Enums replace constants• Typed arrays replace delimited strings• No in/out parameters
Writing a Service Object
• Typically written by device manufacturers and shipped with the device
• May be installed by INF or stand alone installer (drag-and-drop)
• Derive from either Interface, Basic, or Base class

POS for .NET Supported Devices
Writing a Service Object
• Interface classes • Abstract classes for each of the 24 UPOS defined
device categories (Msr, Scanner, etc.)• Implemented as classes instead of interfaces so we can
rev them to match UPOS without breaking clients
• Basic classes• Implemented for all 24 device categories• Derive from interface classes• UPOS common functionality fully implemented• Integrated device statistics support• CommonProperties class allows full access to
internal properties
Base Classes
• Available for:• CashDrawer, CheckScanner, LineDisplay, Msr, PinPad,
PosKeyboard, PosPrinter, Scanner
• Derive from basic classes
• Implement device specific functionality
• Easiest way to implement a service object
• <DeviceClass>Properties class allows full access to internal properties
Service Object Attributes
• *PosAssembly – Assembly contains SO(s)
• *ServiceObject – Class implements SO
• HardwareID – Maps SO to hardware• Can also use Control Configuration XML file
* Required attribute
[assembly:PosAssembly("Manufacturer Name")][assembly:PosAssembly("Manufacturer Name")]
[HardwareId(@"HID\Vid_05e0&Pid_1300&Rev_0201")][HardwareId(@"HID\Vid_05e0&Pid_1300&Rev_0201")]
[ServiceObject("Scanner", "MyScanner", "Description", 1, 9)][ServiceObject("Scanner", "MyScanner", "Description", 1, 9)]
SOs & Config: Locations
• Put your Service Object DLLs in"%ProgramFiles%\Common Files\Microsoft Shared\Point Of Service\Control Assemblies"
• Put your config files in"%ProgramFiles%\Common Files\Microsoft Shared\Point Of Service\Control Configurations"
• Configurable in the registry:[HKLM/Software/Pos for .NET]
Device Management
• WMI Classes (root\MicrosoftPointOfService)• ServiceObject – Information about installed SO’s
• POSDevice – Information about installed devices
• LogicalDevice – Alias for POSDevice
• DeviceProperty – name/value pair set on POSDevice
• Posdm.exe command-line tool• Exposes WMI via command line
• MMC snap-in coming in next release
• All tools support remote management
What you have learned
WEPOS provides a common platform for Point of Service applications
Simpler to install and support than XPe, but requires some post install manual setup
POS for .NET 1.1 makes it easy to develop UPOS compliant applications using .NET
