Hi community,
I have the following problem which i´m not able to handle.
I would like to have a dynamic QR code on my form, which is composed of the entries made by my customers in the form.
The plan is to have my clients this PDF, fill it out and return it to me. The QR code should then be generated on my computer.
The problem is even though I have Adobe Acrobat Pro DC, the QR code box is always gray.
On the Internet I keep reading that you need LiveCycle Reader permissions, but does that also apply if you own Acrobat Pro and only want to generate the codes for yourself?
I'm slowly getting really desperate and would be very happy about help.

The QRcode field is greyed out in Acrobat Reader but it works fine under the gray mask.
==> You can create a form with a QRcode field with Acrobat Pro and the QRcode will not be visible for Acrobat Reader users.
But you don't care : When you will receive the forms back and open them with Acrobat Pro (or Acrobat Standard) the QRcode will be enabled and perfectly visible and usable.
If you need a QRcode visible and usable in Acrobat Reader feel free to contact me privatly.
Open this file with Acrobat Reader to see a great sample: https://abracadabrapdf.net/file/RATP-position-geographique-des-stations.pdf

I am using Adobe Acrobat Pro DC on my Mac and the field is not visible for me as the creator.
So do i have to change something, is this a bug or what can i change?

I will only reveal a very small part of my trade secrets to you: it is not a form field…

[REMOVED BY MODERATOR]
And then there are creatures trying to cash in on those who don't have enough knowledge, on a community forum, on software owned by others. Anyway, as soon as I find out, I'll share it with you for FREE, which is the very foundation of this forum.

Basically one of the solutions is to use Javascript, and transform the data into an image in Base64. I still can't help you much more, with examples, because I'm still going to study this code in detail.
Heres the code you need:
this._add_qr(event.target.name, 822, 283, 1.2, 8, 'M'); // to call functionand:
var qrcode = function() {
var r = function(r, t) {
var e = r,
n = f[t],
o = null,
i = 0,
a = null,
u = new Array,
g = {},
c = function(r, t) {
o = function(r) {
for (var t = new Array(r), e = 0; e < r; e += 1) {
t[e] = new Array(r);
for (var n = 0; n < r; n += 1) t[e][n] = null
}
return t
}(i = 4 * e + 17), h(0, 0), h(i - 7, 0), h(0, i - 7), l(), s(), w(r, t), e >= 7 && v(r), null == a && (a = p(e, n, u)), d(a, t)
