I’m putting together a single card that keeps every student secure, connected and accounted for. With one tap the card must open doors, pay for meals, log attendance automatically and, when a student feels unsafe, trigger an SOS call while broadcasting real-time GPS coordinates. The moment SOS or any geofence breach occurs, the right staff member has to see an alert immediately. Three user groups will interact with the platform. Students need a simple companion app or portal to view balances and safety status. Teachers must be able to take attendance and receive emergency notifications for their classes. Administrators require a full dashboard: live location map, transaction logs and system configuration controls. You’re free to choose the hardware interface—RFID, NFC, BLE or a clever mix—so long as card issuance stays straightforward and encryption protects all data in motion and at rest. The back end can sit on AWS, Firebase or any suitably secure stack; just outline your approach. I also need to know how your design delivers sub-five-second alerting (push, SMS or email) and role-based access control. Deliverables • Prototype card, reader and complete software stack • Student, teacher and admin interfaces (web or mobile) • Source code with build instructions • Deployment guide and one hand-over session Acceptance criteria • Access control, cashless payment, attendance, SOS and GPS tracking all verified in a live test • Emergency alerts reach designated roles within five seconds • Attendance records prove at least 99 % accuracy • Role-based permissions confirmed for students, teachers and administrators NOTE : LOOKING MANUFACTURER ONLY IN DELHI NCR ( INDIA )
