\# Configure camera (scanner) One of the features of the Point terminal that can be used by your SmartApp is the camera as a QR code or barcode scanner, essential for in-person paymentssuch as Pix or boleto . In addition, it can also be used to scan QR codes specific to the establishment and product barcodes. To implement this feature, use the \`launchScanner\` method from the \`cameraScanner\` class within the \`MPManager\` object, and differentiate which type of code you want to scan through the \`ScanType\` class, which can be: - \`CAMERA\_SCANNER\_QR\`: represents QR code reading. - \`CAMERA\_SCANNER\_BARCODE\`: represents barcode reading. Additionally, through the \`ScannerFlowRequestData\` class you can also control some visual features of the \_scanner\_ screen: | Feature | Type | Description | |---|---|---| | \`isLanternOn\` | \_Boolean\_ | Indicates whether the scanner should open with the terminal's flashlight on. If yes, \`true\` and if no, \`false\`. This feature is not available for QR code reading, only for barcodes. | | \`initialOrientation\` | \_String\_ | Defines the initial orientation of the screen where the scanner will be displayed, which can be vertical or horizontal. The possible values are:   
  
 \- \`null\`: the orientation will be determined by the default implementation of the scanner screen, which is currently always portrait (Portrait).   
 \- \`0\`: orientation defined as landscape (Landscape). It is recommended to pass this value as \`ActivityInfo.SCREEN\_ORIENTATION\_LANDSCAPE\`.   
 \- \`1\`: orientation defined as portrait (Portrait). It is recommended to pass this value as \`ActivityInfo.SCREEN\_ORIENTATION\_PORTRAIT\`. | See below an example of scanner feature implementation.
