This application is the core of IC+. Paper prescriptions are scanned so that the image can be retained electronically (a program called Walgreens VISION). The scanned image can then be sent to other Walgreens locations through DWB (Dynamic Workload Balancing) or POWER (Pharmacy Optimization Within Enterprise Re-Engineering) for various purposes (data entry or data review). The paper prescription is kept on file per local or state laws. In certain states, the computerized image serves as the legal copy of the prescription and the original paper hard copy becomes the Third Party Audit Record (3PAR).
