From July 1-Aug. 31, WSU departments can save an additional 3 percent on their bulk mailings by using a Mobile Barcode (QR Code). This second code is the newest thing and can be used for a lot of different applications. When scanned, it can take people to their departments website for special events/game schedules, or it can display your name, number, email, mailing address, etc. Please contact the Campus Post Office at 978-3550 on how integrating technology could increase the value of your mailings, and for a short time save you money.
