Controle de presença utilizando RFID: um estudo de caso utilizando a linguagem Ruby

Abstract

There is great difficulty to control the presence of participants in an event or of students in a classroom, with calls, lists, stamps or persons making the control input. These procedures can often lead to delays or loss of time, both in times to make the control as to relay the information to the system. Seeking a simpler solution to this problem, this project aimed to create cards with radio frequency tags, which students or participants to pass the entrance halls to register their presence and they would have immediately passed on to the system's event. RFID readers would pass the information to a system made with Ruby, who would record the information in the appropriate data base, the system would access the event to check the frequencies. It created a kind of service to be accessed by the systems. The results indicated that the process can be used to speed access and control of presence of participants at events.
