NFC is simply a newer technology to interact with the first two. Think of MIFARE as being the most used type of RFID tags. MIFARE chips represent approximately 80% of the RFID passive tags in the world. MIFARE is owned by NXP semiconductors which was previously known as Philips Electronics. It is often incorrectly used as a synonym of RFID. MIFARE, is a trademark for a series of chips widely used in contactless smart cards and proximity cards. This is to allow both devices to become reader, antenna, and tag. NFCs main purpose was to break out of the standard tag/reader “read-only” pattern. NFC was created as a new way of communicating with other RFID tags. NFC operates within the same range of frequencies of RFID. These protocols enable two electronic devices to trade information within 4 centimeters (~2 inches) of each other. Near Field Communication (NFC), is a set of communication protocols. an antenna (ranging from Low to High and Ultra High frequencies).The use of RFID always implies three things: They are capable of operating hundreds of meters from the closest RFID reader. Some tags are active and require a local power source, such as a battery. Some tags are passive, therefore they are activated by the electromagnetic fields generated by nearby readers. Radio Frequency Identification (RFID), is a technology that uses electromagnetic fields to automatically identify and/or track “tags” that contain electronically stored information. So, before we jump in let’s learn some basics. This is not intended to teach you all about RFID, NFC, and MIFARE hacking. MIFARE Classic ones especially, which are still widely used nowadays despite the many hacks found throughout the last few years. The goal here is to cover the process of cloning and editing RFID tags. Other Proof of Concepts (PoCs) I’ve read were not so thorough, this is my attempt at being more thorough so others have a better understanding. This is not a new topic, but rather my own vision of the many different things that’ve been done concerning RFID.

As we start this series, you won’t find anything that hasn’t already been discussed before.
