Hello gliders!  
Let me ask you a three magic new-year puzzle i met.  
My head is broken attempting to solve this)

1. Back reading of Bar-code does not work(  
I use “Barcode” as Column type for the Column “A”, based on my RowID (It is special text column type). I see there is a bar-code picture here in A in the data editor. Okay.  
Then i put this Barcode on my screen as an Image, and read this Bar-code Image directly from a screen by Barcode Scan Button - writing the result to the Text Column “B”. So we expect “B” should be the same = “A”, but it is not true (((  
B is

- a number,
- and of course is not equal to A (RowID).  
What is wrong?

1. How to take and send the Barcode Image from Barcode Type Column?  
The Barcode Column Type is emulating and looks like an Image, but in reality this is a text (maybe JSON?).  
Then i need to send my user this Barcode as an Image, but it is not image - It is a text. When i trying to send my Barcode by email or by Sharing option - it sends the text, not an image. How can i send to user the Image of Barcode?

2. QR vs Bar  
In general i need the QR-code, not Bar-codes for my feature.  
But there is only Bar-code Glide native **reader\scanner for one-click reading\scan it.**  
I sow there is a similar subject here at this Community Forum, but it is  
hard to understand (doesn’t works in my copied App),  
and seems there are not one-click scanner of QR-codes.  
Is there somebody who can prompt how we could scan QR-code in one click?

Have happy New Year!

Hi Aleksei,

@ShantanuIyengar released [this QR code scanner showcase](https://community.glideapps.com/t/glide-qr-code-scanner/36519) 11h after your post 🙂  
Maybe mind-reading.  
Hope it helps.
