Registering Custom Identifier Code Handlers

The ability to register custom identifier code handlers has been added through the method RegisterIdentifierCodeHandlers.

Handler Capabilities

The handler can:

• Validate the format of the identifier code
• Perform checks and provide results

One code can be processed by multiple handlers independently. For example, one mark can be verified through a fiscal registrar and through the “Honest Sign” system.

IIdentifierCodeHandler Interface

IIdentifierCodeHandler includes the following methods:

• IsIdentifierCodeSupported — determines whether the handler can recognize the code (for the order item or modifier) and returns specific flags
• VerifyIdentifierCode — performs verification of the identifier code added to the item or modifier

Handler properties:

• SourceKey — a unique key identifying the handler
• Description — a human-readable description of the handler
