This research aims to develop a computer application that allows the automation of the registration of attendance to classes of teachers and students of the Polytechnic School of Chimborazo (ESPOCH) using radio frequency identification devices (RFID), to optimize attendance registration times to class and generate reports up to the current date. Observation and interview techniques were used to identify requirements, which were applied at the ESPOCH School of Systems Engineering. The SCRUMBAN agile software development methodology was used for the project stages. In addition, the prototype of an RFID device was designed and implemented, with ARDUINO MEGA and an RFID reader. For the evaluation of software quality, the research focused on the productivity characteristic, establishing two metrics: time to complete a task and productive proportion; Based on the ISO / IEC 9126-4 usage quality standard. For this, the time capture method was applied and the data obtained were evaluated by means of the T-student statistical test. This process resulted in the acceptance of the alternative hypothesis that indicates: The computerized system to automate the registration of attendance to classes of teachers and students reduces the time of attendance registration, improving productivity in the institution. An improvement result of 66.46% was obtained with the use of the system.
