i believe i have to much time today but i found another page http://www.csi-labels.com/pages/products/dualsensor.amem2.html there is a dual tag . have this with kmag to do? or is this another producer but this looking near the same as kmag have as patent. this grocery label looks also the same in my opinion. http://www.csi-labels.com/pages/products/gsl.am2.html maybe iam false just speculating.
