My PSO (professional services organization) is just wrapping up a project that helps bands track their "true" fans by using handheld PDAs with barcode scanners. Music fans are provided with plastic "band" cards with a barcode label on them. Whenever they purchase band or concert products, their card gets scanned and recorded. This allows the team to record and reward fans for their ongoing support through a variety of "true" fan programs and special promotional offers.
How does the mobility solution fit in? Often, band related concerts and products are purchased from "mobile" sales locations that are not networked into existing database systems. Therefore, the sales staff use mobile barcode enabled PDAs to record "true fan" sales activities that can be recorded and synchronized with the main database systems at a later time.
This solution was developed using MobileDataforce's PointSync Software Development Kit. The barcode scanners were Socket Bluetooth scanners that work with consumer grade PDAs.
