Huseyin Aliz myBiss ApS | Hi All.
Hope everyone are healthy and safe. I am currently researching if i can scan barcodes from ewb2, and have searched the forums and found few suggestions (cordova for instance). I have found following (html5 access), which looks nice, but would like to know if others have interesting inputs as well? https://blog.minhazav.dev/qr-code-scanner-end-to-end/ Thanks in advance. Regards, Huseyin A. |

I did it before in a project, both bar codes and QR codes. I don't have the source available right now, but assure you it's doable. It is no longer necessary to use Codova, you can do it all in EWB/JS with modern browsers (except not IE) as it doesn't support the HTML5 features for camera access (or quite a few others). The first time you use it, the user has to grant permissions to access the camera in a pop-up window, otherwise it's seamless. If you have a choice, I'd recommend QR codes over bar codes. QR can hold a lot more information. Good luck, Erick EWB Programming Books and Component Library http://www.erickengelke.com |

Huseyin Aliz myBiss ApS | Hi Erick,
Thanks for your input. I would rather use EWB as much as i can. Currently it seems that barcodes are primary used, but having an option for using both qr and barcodes + uploading signature (picture) from the smartphone/pad would satisfy my needs ![]() If you find the source someday, I would be glad to see how it can be done. Thanks again.

The work in progress works well with both bar codes and QR codes. I haven't tested on a phone yet or with multiple cameras. You can see the working prototype at: https://erickengelke.com/nice/testbarcodeqr.html Hint, it needs to be https or the camera won't work. That's part of the WebRTC standard. It works with every browser except IE. I need to add support for multiple cameras and clean up a few things before it's ready. Probably I'll release it before Monday. It's a $50 cost for a lifetime subscription to the whole toolkit, you may find other things useful. Erick EWB Programming Books and Component Library http://www.erickengelke.com |

I've completed adding it to the nice toolkit. Anyone with a subscription can download the latest version with Barcodes/QRcodes. It works on computers and phones alike. My Pixel 4 couldn't scan well from the front facing camera - too low quality, but the rear facing camera works perfectly. See the sample in: https://www.erickengelke.com/nice/samples.html The QR page is about 30 lines of header and 60 lines of code to do everything you see for QR and Barcodes alike.
