Question: What do you call the square brackets used to target a barcode/QR scanner? I thought this would be called "reticle," but when I Google the term, all I see are circles with crosshairs. Is there a more precise term, especially in the context of a digital device/camera, or is reticle the word?

Answer: 
I think the best term *is* "reticle." Businesses that make the glass used in cameras call them reticles. See the images on this site: <http://www.reticles.com/reticles_kr900.htm>.
According to [ehow](http://www.ehow.com/how_8488499_read-qr-codes-iphone.html) it is called a reticle. But I usually just hear it called the QR reader.
