Users can use the Invengo RFID SDK to develop their own applications for collecting
tag data. The Invengo RFID SDK is the middle layer between the system and the
background application software, and provides the software interface for the user's
secondary development.
Please refer to 《Invengo ReaderAPI Technical Reference Manual》under SDK
for the call and development instructions ofAPI application interface program.
5、Barcode(optional)
The reader can be equipped with a variety of high performance barcode scanner. Users
can collect 1D or 2D barcode data through the built-in barcode demo, or can develop
applications independently to collect barcode data.

1) Barcode demo
Launch the BarcodeApp on reader.
Press the Start button or handle to scan for barcodes.
Press the Clear button to clear all scanned bar code data.
Press the Setting button to set barcode parameters, such as timeout, illumination level,
multi decode mode, clear mode.
For the secondary development method of barcode module, please refer to
《Invengo Barcode ServiceAPI Reference》
In order to ensure the correct reading rate and short reading response time, please
ensure that the bar code window of the device is 20--30cm away from the target bar
code. If the bar code is printed on a smooth reflective object, please keep the bar
code window and the target bar code at an Angle of 15°--30° before reading.
Otherwise it may have a certain impact on reading speed.
