Abstract
With the Covid-19 pandemic, contactless and remote payment options have started to be used more widely. NFC technology is also used for contactless payment. In this study, it is aimed to create a payment system using NFC. The design of the payment system used a portable NFC, an Android phone with version 4.4 or higher, an NFC card, Firebase database from Google, and tokenization. We can define tokenization as generating a random string of text with your credit card number. First of all, the developed application must be downloaded and installed on the phone. With this application, the phone will act as a POS machine. Users can use the phone as a POS and make transactions using it. In this system, only a random text string will be visible in an unauthorized access to the database. In this way, security and confidentiality are provided in the system.
