Extra label inside seems do-able to me .... Make sure your recipient knows it is there ...
The quilts will probably outlive the technology .... I think that is why some people keep quilting journals ...Make your labels detailed enough to be identified by your third generation ... initials only and year of construction just won't tell much at that late date. I am talking far in the future, not just today.
Even QR codes may not mean much at that point.
In the short-term, if you are shipping and entering public quilt shows, perhaps it is worthwhile to do the expensive route of chips and insurance ...... I haven't made any quilts at that level just yet, so those who have done so would be better able to address this issue.
Take photos of both front and back, and an up-close picture of the intricate quilting ... and a readable, blown up picture of your label .... and keep a real copy in an album ....

Did you catch the thread on QR codes and making them on your label? You can do it for free, and it is very easy.
http://www.quiltingboard.com/t-121655-1.htm here is how to print a code, so any cell phone (with the app) can read it. If you sew the label into the quilt, so that it would be hard to remove, it would help.
I have also heard of making an extra label inside the binding. So, if you see your lost/stolen quilt, you still have proof it is yours, even if they have removed the label.
