Pdf417Demo not scanning

[shepherdsiduli]

I have been trying to scan Pdf417 barcodes using the Pdf417Demo app but to no avail

I uncommented the following code in the index.js file : alert("got result " + data.data + " type " + data.type);
I found out that data is undefined

I am able to scan from a PC but not from paper

Hi,

we are able to scan the barcode on both iOS and Android devices (screenshots attached).

To scan the barcode, one barcode module (the smallest black dot) should be at least 1px wide on the image. Also, your device should have autofocus. These are the only limitations.

Which device you use for scanning?

Thanks for the feedback, when I scan the from a pc screen it works However when I scan from a printed hardcopy it doesn't work, can you please download the pdf below and print it then scan from the hardcopy

I am using a samsung galaxy pocket and samsung s4 for scanning

[Cerovec]

On samsung galaxy pocket scanning doesn't work because that device doesn't have autofocus, and it supports video resolution of only 320p. That's in line with our usual device and software requirements.

However, on SGS4 scanning should work even on paper.

Can you:

• confirm that on SGS4 you also have problems with scanning?
• send us a photo (taken with SGS4) of the printed version of that barcode?

Thanks!

Yes, I am having problems on the sumsang s4

Please see photos below:

Can you use this link to download the .apk we built and install that app on SGS4?

Also, please try our demo app from google play store https://play.google.com/store/apps/details?id=mobi.pdf417

The behaviour on both apps should be the same. In our test, we managed to scan your barcode with both apps on SGS4.

Thanks a lot I tried the app on a Samsung s3, and it worked perfectly, I think there is something wrong with the s4 (settings)

Thanks a lot
