NFC Payment System
Introducere
Using an Arduino microcontroller and an NFC module, a Near Field Communication (NFC) Payment System is a system that enables contactless payments. The system initiates and completes a payment transaction by exchanging data between the NFC module and a compatible device, such as a smartphone or contactless card.
When a user initiates a payment, the Arduino microcontroller processes the transaction and transmits a signal to the NFC module in order to establish communication with the user's device. The user then affirms the transaction via their device, after which the system verifies the transaction and completes it.
Overall, an Arduino-based NFC Payment System provides a basic and efficient method for making contactless payments that can be implemented in a variety of applications, from vending machines to transportation systems.

List of parts
LCD 1602A: The LCD 1602A is a common character display module seen in embedded systems and electronic projects. It has a 16×2 character display, therefore it can show up to 16 characters per line for a total of 32 characters. It interfaces with microcontrollers via a 4-bit or 8-bit parallel interface and is controlled by a Hitachi HD44780 controller.
PN532: The PN532 is a highly integrated NFC (near-field communication) controller chip that enables device-to-device contactless communication. It is compatible with a variety of NFC standards, including ISO/IEC 14443 Type A/B, FeliCa, and ISO/IEC 15693. It has a wide range of uses, including payment systems, access control, and mobile devices.
SD Card Module: MicroSD card modules are small electrical devices that simplify MicroSD card use. It has a MicroSD card reader, voltage regulators, level shifters, and SPI communication interface circuits. The module integrates easily into data logging, audio recording, and video recording projects. It may also increase microcontroller storage. Many embedded solutions need the module to read and write MicroSD cards quickly and reliably.
Arduino UNO - a microcontroller board based on the ATmega328P processor. It is one of the most popular Arduino boards and is intended to be a simple foundation for constructing a variety of electronic projects.
