I know QR codes seem to be a bandwagon item that only a few have jumped on, but I really think they are an excellent way to link to information. My son is an avid chess player and is registered with the US Chess Federation. He recently received a new membership card in the mail that was tagged with a QR code. See below.
I thought the QR code would probably take you to the USCF site and you would have to log in, etc. Nope. This wonderful little code takes me directly to my son’s rating info., past tournament scores, etc. No more typing in the address, logging in and scrolling through info. Scan the code and there you are. Bam! Well played USCF. Well played.
