Application of RFID reader for recording student attendance in class

Razmatra se sustav za evidenciju studenata skeniranjem studentskih iskaznica. Sustav se sastoji od ACR122U čitača kartica, Raspberry Pi Zero W računala za upravljanje čitačem i slanje podataka Bluetooth vezom na mobilni uređaj. Kako bi Raspberry Pi Zero W što efikasnije obavljao svoj zadatak napravljena je jednostavna Linux distribucija samo za tu namjenu. Na mobilnom uređaju se lista studenata trajno pohranjuje.A system for keeping student records by scanning student ID cards is being considered. The system consists of an ACR122U card reader, a Raspberry Pi Zero W computer for controlling the reader and sending data via Bluetooth connection to a mobile device. In order for the Raspberry Pi Zero W to perform its task as efficiently as possible, a simple Linux distribution was created just for that purpose. The list of students is permanently stored on the mobile device
