Barcode Reader Interface

IBarcodeReader

If a PED can scan a barcode, LS Pay gives access to a service handling the functions to activate and read.

IBarcodeReaderService

Not all functions might be used by a given PED:

  • SetMode sends information to the PED about what type of scanning is to be expected.
  • PowerOn activates the reader.
  • PowerOff deactivates the reader 
  • OverrideScanEvent indicates if the POS needs to override the event and call PowerOn (true) or if the PED handles the functions automatically (false).
Copy 
public interface IBarcodeReaderService
{
    void SetMode(ScanMode mode);
    void PowerOn();
    void PowerOff();
    bool OverrideScanEvent();
    event BarcodeEventHandler BarcodeRead;
  }

The barcode will be returned in an event and the POS will need to handle what to do when a response has been delivered, to power off or read another.

public delegate void BarcodeEventHandler(string code, BarcodeType type);
