アインお薬手帳, also known as the Electronic Medication Notebook, is an application that enhances traditional electronic medication notebooks by incorporating the "Smart Pharmacy" feature. By registering with an Ain Group pharmacy, users can access three convenient features: prescription submission, notification upon medication readiness, and medication list presentation, all through the "Smart Pharmacy" feature.

Users can receive medication information directly from Ain Group pharmacies without QR codes, enabling seamless web transmission to the app. Additionally, users can register medication information from non-registered pharmacies by scanning QR codes. The app allows for photo registration of over-the-counter medications and prescription drugs, apart from utilizing QR codes for information input.
