Suggestion for faster QR code scanner software

I found faster QR code scanner software than the currently used HTML5-qrcode. It uses webassembly. It can be found at github.com/undecaf/barcode-detector-polyfill . A demo at codepen.io/undecaf/full/LYzXXzg .

For me the demo works with Android, using Chrome and Firefox. Supposedly it works also with Safari on IOS. It recognises a qr-code almost immediately, while the current scanner is noticably slower.




 

Hi Frans

You might want to edit the menu item, change Checkin Interval parameter. The lower the value, the faster the checkin process

Hi Tuan,

Thanks for your suggestion. It is already at 2 seconds. What happens during check-in, it takes a long time before the scan succeeds, 10 seconds and more sometimes. Sometimes it fails altogether - low contrast on the telephone or with a paper ticket. I have no influence on the lighting conditions on the spot...

Making the check-in interval lower causes multiple check-in actions when the qr-code suddenly is recognised and the response then is "already checked in", or in case of group ticket, multiple persons are checked in. The current implementation causes scanning to continue while the pop-up is shown, I guess.
