As the advancement of technologies becomes more progressive and efficient, State Polytechnic of Malang would like to start digitalizing most of the student attendance system by using mobile-based QR code scanning for student identification.They aim to improve their student attendance system to be more effective and versatile than the previous system.A contactless attendance system in offline events is urgently needed in the pandemic.The manual attendance system still uses papers and signatures can support the spread of the virus.The mobile-based QR code attendance system is expected to minimize direct and indirect physical contact between the event organizers and the attendee, thus minimizing the widespread of the virus.Besides, a paperless attendance system can help the environment by decreasing paper consumption, contributing to 42% of the global wood harvest.The previous student attendance system within the campus was still using a standalone, third-party QR code scanner that was connected to a laptop.After the student's QR code had been scanned, the student's data would be displayed instantly on a laptop web page.This cycle is inefficient since it requires two devices, and the QR code scanner cannot instantly display the scanned barcode data.Moreover, the device itself is bulky, thus making it less mobile than smartphones.To overcome those issues, the mobile-based QR code attendance system can be the solution, as it would only utilize one device for scanning and displaying the data instead of two.Furthermore, this system can be used on different occasions and events everywhere, from wedding invitation management to an academic graduation ceremony.Seven out of ten participants agree that this application helps to reduce the possibility of attendance fraud and attendance abuse, two out of ten are still unsure about it, and 1 out of 10 denies the statement.The optimal brightness for the smartphone screen used to display the QR code is between 25% and 50%.Moreover, the optimal distance of the scan for the smartphone screen used to display the QR code is between 10cm to 30cm.
