Both business staff and customers can scan the stick-on "Customer Service Tags" with any smartphone to instantly see last service date and services rendered, who service was done by, service history, appointments that have been set for future services and much more. Stick-on Tags can be placed on desktop and laptop computers by computer service companies, on car windshields by automotive repair and other types of service shops, and also on medical and other cards by healthcare and other service providers. Customers can also place tags on their personal Customer Service Cards. Automatic email reminder messages can be sent for delivery on any future date and time. The simple act of a customer reminder - contacting a customer the day before appointments, has been found to decrease customer missed appointments by over 50%. Customer services also vary according to individual customer needs. Therefore, Customer Profiles can be customized to fit service frequency choices, desired service levels and other customer preferences.
