NB: You will see "update" on playstore if the app is installed from playstore. Otherwise it will show "open". If you have installed SelfScan from other stores then update from that store or uninstall(one time) and reinstall from Google Playstore to get the update. By using SelfScan, documents can be digitized and saved for future use or can be shared with anyone using the mobile phone. Want to have a safe scan app for self? Self Scan is your ultimate answer. Bengal has its own scanning app now.
