The first QSL postcards were issued around the early 20th century, primarily by amateur radio operators. QSL cards, which stand for "QSL" meaning "I acknowledge receipt" and were traditionally sent to confirm two-way radio communication between amateur radio operators, became popular as a means of confirming radio contacts, verifying reception reports, and exchanging information about the contact. The exact date of the first issuance may vary, but they became commonplace as radio communication grew in popularity in the early 1900s.
