This is a game changer! After trying many different apps and methods on how to get business cards from tradeshows into our crm I finally splurged and purchased this. BEST DECISION EVER!My team typically will travel to around 8 events a quarter, and we will see 1,000's of business cards pass through our office every month. Getting all this data into the CRM, accurately and quickly is quite a task. Team members have tried phone apps, old school typing into excel, etc. This was by far the best.The accuracy is great, traditionally styled business cards go in with 100% accuracy nearly everytime. New modern designs (With large off center logos, random fonts, and color) still get picked up with 85%+ . accuracy. It's truly a huge time saver. The only cards it doesn't work on are the ones with large areas of smooth raised ink on them.As far as registration, is does limit the license to one, but per operation system. We currently use it on a Macbook that travels to the shows, and we have a ""Business Card Station"" which is an old windows computer we leave at the office. We didn't have to purchase a new registration to set both of these up.I highly recommend this product.
