Which apps have u tried ?

 

I found that rather then getting right up on top of the bar code, it helps to scan from a considerable distance away.

I use the shop savvy scanner and it works really well when I pull back to what I initially thought would be too far to scan, like 8-10 inches away from the bar code. Thus far, I've been able to scan pretty much whatever I want without issues. If I'm too close, forget it.

 

You don't really need to hold it too far away. I mean, this about the distance that mine will work. It just focuses and then the barcode is scanned almost immediately.



Make sure the lense on the camera is clean. It seriously does improve camera quality and sharpness (which is what you need the most for barcode scanning).

 

Methinks your phone is defective if it doesn't focus period. Or maybe there is a software issue. You should be able to see it refocusing regularly.

 

This thread got me curious because the bar code reader function always worked well on my Moto Droid. So, last night I tried "Barcode Scanner" by ZXing Team, seemed highly rated and showed over 50 million DLs.

Anyway, I couldn't get it to read the codes on a gift card I had handy, kept trying to focus over and over. A key component of an auto-focus failure is lack of contrast / poor lighting. I picked up a little LED flashlight and shined it near the gift card. That was enough. Picked it up right away.

This particular app allows you to have the LED/flash turn on in low light situations, and the default setting is OFF. I changed the setting to ON and tried it, instant read! I'm posting this as an addition to the other good answers already shown above, hope it helps.

 

I have had times where it took the pic before focus was achieved, yielding disappointing results compared to the pics the Nexus is capable of when fully focused. It does sound like something isn't quite right with yours, hope you can get it resolved.

 

I am having problems with it also. I tried using ZipList and Baarcode Scanner. I keep getting yellow lines going back and forth on the line.

 

hi......want to know what are the better option to scan barcode with Android app?
