Employee attendance's data shows the presence of each employee in a company that records the time of employee start to work and time for completion work of employee. This data is useful for monitoring employee performance includes working hours, attendance, overtime hours, even for employees who are on duty outside the office. Attendance also has a significant impact on the amount of salary received by employees per month. Companies in Indonesia generally apply manual attendance, using books or manual machines, for example manual attendance machines. This method is inefficient because it requires many forms and is time-consuming. In addition, there are types of electronic attendance, using machines such as fingerprint attendance machines. This method is better than manual attendance methods, but sometimes there are obstacles, namely the machine is less sensitive in reading fingerprints, for example, fingers in a wet/dirty or injured condition. so that finally attendance is done by manual recording. Based on the description above, the author proposes research to develop an employee attendance information system using Radio Frequency Identifier using Near Field Communication (NFC) cards. The use of NFC cards for employee attendance by tapping the card on the NFC Reader device. The use of this technology is quite practical because the sensitivity of the device is good and can read cards accurately. While the software development model uses a prototyping development model that can be adjusted to user needs. The research method begins with a literature study on NFC cards, observing employee attendance methods in the company, designing a database design, building a system that is compatible with NFC readers and writers and user interface displays and conducting system trials. Testing the system by reading and writing data on the NFC card on the card reader/writer unit, the test results showed that the maximum reading distance for the NFC card was 7 cm with a reading angle relative to the NFC reader/writer with 300 can read the NFC card.
