I am so brilliant

My son sent me a new Plantronics bluetooth for Fathers day, having some problems with it so I will get it replaced under warranty. A couple of years ago, I had to have one replaced and the person on the phone had to have the numbers off the headset. Those numbers are so small that I can't read them even with a magnifying glass. The light went on so I took my camera and set it on super macro and took several pics about 1/2" from the headset. I put the card in the card reader on the computer and the numbers looked like a billboard. My arm's hurting patting myself on the back......
