➀ The project demonstrates an IoT-based metro ticketing system using RFID cards for fare management and balance updates；
➀ Involves two main devices: a card recharge module (managed by staff) and entry/exit scanners with real-time IoT dashboard monitoring；
➁ Utilizes IndusBoard Coin microcontrollers and RC522 RFID modules, supporting web-based balance tracking and automated gate control via servo motors.
➀ IoT-based RFID attendance system using ESP32-S2 and MFRC522 module to scan cards and record real-time data;
➁ Features web interface for attendance tracking, NTP time synchronization, and CSV data export for records;
➂ Supports new user registration via web form and integrates SPI/WiFi libraries for seamless operation.
➀ Pragmatic Semiconductor has announced a new RFID tag product line for marking retail items.
➁ The product line, branded 'NFC Connect', is a passive IC powered and read using near-field communications.
➂ It is compliant with ISO15693 and NFC Forum Type 5 standards and can be easily integrated into existing workflows.
