Welcome to the repository for QR-ID, an application designed and coded by me for my group's research requirements. This was our research entry for our Grade 11, school year 2024 - 2025.
The goal of this app is to allow administrators to scan public school student ID attendance using QR Codes. This is an alternative to the current digital methods such as NFC and biometrics, which have their own set of problems.
Biometrics authentication is arguably the most secure as fingerprints are (mostly) unique. However, especially as disease rates rise and hygiene in many public schools is abyssmal, it raises health concerns and can even be a cause of contact illnesses.
NFC authentication is also very common among universities and private schools, however the cost of making IDs with NFC chips are expensive, and special equipment just for NFC identification is even more expensive. Also, NFC IDs cannot be replicated without special hardware, and are prone to weathering and rain damage depending on the quality.
QR codes are thus the safest and most reliable option for public schools. They can be easily replicated just by taking a picture of the code. There is no special equipment needed to scan a QR code, and any camera or smartphone will suffice. QR code production is also extremely cheap on plastic card IDs as they are just pictures.
