Abstract: A safe is a tool used to store valuables such as money, jewelry, securities, and so on. The crime rate is increasingly high in this country, especially the crime rate of theft, which encourages people to create safes with extra security systems. To achieve a security system that has double or layered security requires sophisticated technology. The technology used in this safe security system uses NFC (Near Field Communication), keypad. By using NFC as a card reader, a special password has been given which can only be read by NFC. Meanwhile, using an Arduino Uno as a microcontroller and a password to access the safe door is very difficult to duplicate.
