How good does a picture of a QR code need to be? [View all]

Last edited Mon Apr 25, 2022, 06:18 PM - Edit history (1)

I used my phone to take a picture of a QR code from the screen of my laptop. It looks like the thing to me but isn't perfectly straight and does not fill the entire screen. I have a paper print out for backup, but it would be much easier to use my phone at five in the morning at airport parking. Thanks in advance.

On edit-am I supposed to scan the QR code from the email on my phone????

I would scan the paper one. nt Phoenix61 Apr 2022 #3

I am just going to wave the paper one at their machine and quit worrying. rzemanfl Apr 2022 #4

Do you have another device with which to try a test scan? nt sl8 Apr 2022 #5

I am worried about the scanner at the airport. I don't know how I could test what I have. rzemanfl Apr 2022 #7

Yes, it wouldn't be a guarantee. sl8 Apr 2022 #8

I have the same email on my laptop and my phone. rzemanfl Apr 2022 #9
