1. NFC What ??
Field Communication (NFC) is a short-range Wireless technology, which works by sending information through radio waves. Like WiFi and Bluetooth, NFC is another standard for wireless data transitions, only with a small difference, it can induce an electromagnetic field through a coil, which allows to send/receive data from passive components.
Don't be fooled by the short range, this technology has several points in its favor, it has a lower consumption than Bluetooth and obviously than WiFi, it can work with passive components, being short-range it doesn't need previous pairing and the information will be sent in when it detects the other device. For this and more, NFC was widely adopted by smartphones, for file transmission, connecting to other devices, but what takes the crown is the payment with the smartphone.
An important part of the NFC Copycat is precisely the NFC module, that is obvious, that is why we have the PN532 NFC Module V3, this module supports I2C, high-speed UART (HSU) and SPI interfaces, our NFC Copy-Cat was designed to use SPI.
The module by itself is already very versatile, it has its own coil that is in the ring painted white. It can be used with our board and since it has support for 3.3V and 5V it can be used with any other development board that handles those voltages like an Arduino Uno, just remember to choose the interface you are going to use. It also already has a lot of support in the community, so it won't be very difficult to learn how to use it.
OK, we have the tool to use NFC technology, and we made a nice development board for it to use. But that's not all, we decided to incorporate one more tool: MagSpoof. MagSpoof is a cybersecurity device created by the famous white hat hacker Samy Kamkar, in an attempt to circumvent the security of American Express. With this tool, he even managed to predict the numbers of the new cards that had been reported as lost or stolen, knowing the previous one, He subsequently reported the security issue to Amex. So, with the magspoof you can emulate any magnetic stripe like the ones on credit cards! You can for example unify all your cards in a single medium... MagSpoof! Now, you have two cybersecurity tools in your hands, with one you can emulate your cards and with the other an NFC module, with the advantage that our board can be programmed in the Arduino IDE, and it has support for a 3.7V battery... Pfff what is coming we will leave it to your imagination.

NFC Copy Cat, is a wireless penetration testing tool intended solely for use in authorized security audits, where such usage is permitted by applicable laws and regulations. Before utilizing this tool, it is crucial to ensure compliance with all relevant legal requirements and obtain appropriate permissions from the relevant authorities.
It is essential to note that the board does not provide any means or authorization to utilize credit cards or engage in any financial transactions that are not legally authorized. Electronic Cats holds no responsibility for any unauthorized use of the tool or any resulting damages.
