Are you old enough to remember when
Reader Service Cards were inserted into the binding of magazines? They were the old world
version of website URLs and QR (quick response) scan codes. Each advertisement in the magazine
had a Reader Service Number printed on it, so you would take your pen and draw circles
around the matching numbers on the Reader Service card, then mail it to the publisher.
Sometimes it would take months to get information in return - if you got it at all. A
typical Reader Service Card is shown below. Look at the bottom of the Poly Paks ad to
see "Circle No. 96 on Reader Service Card."
