What does this QR code I found in Abstergo's office mean?

I found a QR code in Abstergo's office, but I don't know what it means. It just decodes to a bunch of numbers: 12491839.

What is the QR code for?

Solution 1:

There are QR codes around the office on sticky notes which you can interact with by pressing the appropriate interact button. You will notice your tablet thing in the lower left will light up its interact icon when you are close to and pointed at a sticky note. When collecting one it will give you some in game information which I assume the QR code is meant to refer to.

I don't think they have any further use than this.

Solution 2:

Scanned it with my qr reader and it came up as "Secret Note" nothing more.
