So the idea is rather than actually copy and pates the ID number anyhwere to share it, you take a screenshot of the number and share that image file. Bots cannot read an image file, but it can read text as it is put into text forms. So it cannot grab that ID number if it is an image rather than text. And once you have Qtox set up it gives you the option to create a one time QR code each time you need to share your ID number. Personal face to face or an image file is the best and most secure way. :)
Thank you for the explanation. Will look further at it.
