URGENT help needed to work on my RFID project

It is web based project RFID (Radio Frequency Identification) technology is a radio frequency identification technology, a non-contact, two-way transmission of communication technology. It can automatically identify the target through the RF signal, and access to relevant data, identify the work without human intervention, with the development of Internet of things, RFID technology applications more and more widely. This paper presents the design of student attendance system based on RFID technology. Student class attendance system is integrated RFID technology and computer management in one of the modern attendance management system. Only need students to carry the ordinary bank card size of the RFID student card (campus card), through the RFID reader to read the RFID student card, the card after the data through the wireless sensor network transmission to the server, the server data to process, get the results of attendance and storage. Students, instructors or educational administrators can query the results of two query attendance through the browser, students can be printed into a report, to achieve attendance automation. 2. Project Background The hardware part of the attendance system consists mainly of passive tags, card readers, (coordinators, terminals) and servers. When the reader to read the student's campus card, through the network data will be passed to the school server, the service installed on the attendance management system software, the students can collect the school card information processing, automatically record the student's credit card time. Records the attendance of the student. Instructors or students can access the server remotely via the PC terminal in different capacities to inquire about student attendance information. Teachers can also print statistical reports, different identities of different permissions. The reader is mainly composed of Arduino microcontrollers and MF RC522 RFID readers. The RFID reader consists of an electronic tag (campus card), a reader, and an antenna. The structure of the RFID reader. When the electronic tag (student's campus card) into the antenna after the magnetic field, if the reader received a special RF signal, can be obtained by the energy of the induced current to send out the product information stored in the chip, the reader to read the information and I also need explanation of whatever implemented It should be in PHP and MYSQL basically its an online attendance system I will attach the hardware here
