In the digital era, traditional attendance systems remain vulnerable to
manipulation, inefficiency, and lack of trust. This paper presents the design and
implementation of a hybrid system that integrates Internet of Things (IoT) devices with
blockchain technology to deliver a secure, real-time attendance tracking solution. Using
RFID/NFC sensors and a backend integrated with TrustContract (TrustMe.uz), attendance
events are automatically recorded and verified on a tamper-proof blockchain ledger. This
ensures both operational efficiency and legal enforceability of records. Real-world
deployment and testing demonstrate the system's potential for scalability and nationwide
adoption, particularly in developing digital infrastructures like Uzbekistan.
