      preferFrontCamera : false, // iOS and Android
      showFlipCameraButton : true, // iOS and Android
      showTorchButton : true, // iOS and Android
      torchOn: true, // Android, launch with the torch switched on (if available)
      saveHistory: false ,// Android, save scan history (default false)
      prompt : "Ubique la parte detraz de la cédula", // Android
      resultDisplayDuration: 3500, // Android, display scanned text for X ms. 0 suppresses it entirely, default 1500

It might be due to this #532.

The image seems to be based on a low-quality, low-resolution and low-contrast JPEG, and it's not complete: It's cut at the bottom. This image shouldn't be readable.

Can you submit a better and complete image?

its works greate in android but not in iphone

[andersborgabiro]

That's extremely detailed. I can't read it with a new Android phone either. This is no doubt close to or even beyond the resolution limit of video preview.

I think that the

problem is with binary encode on pdf417 at iphone

Check the Zxing documentation for whether it supports binary data for iOS.
