# zbarcam
|
|
|
|
> Scan and decode barcodes (and QR codes) from a video device.
|
|
> More information: <https://manned.org/zbarcam>.
|
|
|
|
- Continuously read barcodes and print them to `stdout`:
|
|
|
|
`zbarcam`
|
|
|
|
- Disable output video window while scanning:
|
|
|
|
`zbarcam --nodisplay`
|
|
|
|
- Print barcodes without type information:
|
|
|
|
`zbarcam --raw`
|
|
|
|
- Define capture device:
|
|
|
|
`zbarcam /dev/{{video_device}}`
