Barcode Scanner Customer Insights

1. I understand that this is just a demo preview their technology and but it's great, it scans barcodes on the way to scan barcodes! I have a dream and in that dream all phone apps that need barcode scanning will have this technology integrated.This is an excellent app with a lot of configurations for more advanced uses.

2. The only option I wish was in the app would be the ability for it to show hidden characters such as start/stop characters, group separators, etc.BEST SCANNER EVER!!!!! Really, the absolute best scanner that has ever existed on the planet! It scans anything and everything (like the really hard databar GS1 codes), it can automatically copy to the clipboard or execute a search (my cell clipboard syncs to my windows 11 clipboard, so this is perfect), and it is crazy fast.

3. The app and the decoder engine are fully customisable - you can use it even with very exotic formats of the picture codes, as well as for reading very damaged codes.A no-nonsense scanner that does a GREAT job at what I want...scanning barcodes.

4. The pop-up tips get a little annoying after a while, I hit "Do not show again", but it doesn't seem to work.It's an amazing application for scan barcode and qr code as well.

5. I've been using other scanners (handheld and android-app based, and I always find something that does not work or a barcode that won't scan.

6. Theres more settings allowing user optimal scanning flexibilityWOW!!! I'm a consumer and my experience with using my phones overy the years for scanning bar and QR codes can be sumed up as MEH.

7. I scan something and I have read the tips but so much transparency in all apps, social media etc that you can't truly understand or trust the companies these days.

8. Continuous can let you keep scanning, but I don't need the massive scrolling list, only the most recent.GET THIS NOW!! I've tried loads of bar and qr code scanners and this one is far and away the best.

9. It picks up and captures codes so frikkin fast... Sometimes with only half the length of the barcode bars in frame.

10. I never seen this type of application yet.Very useful app - It can read both: 2D and 1D codes.

11. Cognex has always been my company's preferred hardware provider for scanning, and their software is living up to their name as well.
