Wireless Attendance SystemProject Budget : $25 Posted Date : 16/11/2018 The attendance system is basically an embedded one. Embedded stands for ‘hardware controlled by software’. Here, the software using a microcontroller to control all the hardware components. The microcontroller plays an important role in the system. The main objective of the system is to uniquely identify and to make attendance for the persons. This requires a unique product, which has the capability of distinguishing different persons. This is possible by the new emerging technology RFID (radio frequency identification). The main parts of an RFID system are RFID tag (with unique id number) and RFID reader (for reading the RFID tag). In this system, RFID tag and RFID reader used are operating at 13.56 Mhz the EEPROM used for storing the details has the capacity of storing 24 bytes at a time. An LED is also used to display the attendance details. There is one master card which is used by the admin in order to know all present and absent (i.e. final attendance list) employees or workers of a day.
Is its cost depend upon the number of RFID cards used for employees?
Yes, the cost mentioned above is not fixed for every case. In the above-mentioned cost, there are eight RFID cards with one Master card. In case of more number of workers than eight, the cost of the product will be increased as 1$ for each card.
