Human blood is made up of plasma, cells, and red, white blood cells and platelets. Human blood groups are classified into four different groups. All four groups are A, B, AB, and O which are also classified according to the ABO system (Ngassaki-Yoka et al., 2018). FastBlood: Blood Donor Mobile App Integrated With QR Code is a mobile app-based solution that allows blood donors to be able to view donation-approved information in the form of digitalization. The existence of the FastBlood app not only facilitates registration and speeds up the process of when to donate blood as donors can fill in the form in the app only and show the QR Code at the blood donation site. Donors can view the blood donation records they have made, the location of donating blood and find out what blood donation events will be held around them. In addition, Blood donors can see how many times they donate their blood and there is also a countdown to blood donors that starts from 90 days from their deadline for blood donation. Thus, users and administrators of the blood donation division can save their time.
