Tape a QR Code right on the mirror that your clients are looking at as they study the work you've done on their head.  When you have someone sitting in your chair for 45 minutes, they are known as a captive audience.  They are stuck in your chair until you release them.  That is the perfect time to explain to them what the QR Code is.  Many of your clients will have SmartPhones.
