Basically there is an active NFC enabled device (the reader) and a passive device (the tag). NFC nowadays is used for access cards, public transport, some more and in this case: Vending Machines. NFC stands for Near Field Communication and is used to communicate over short distances.
MIFARE CRACKER HOW TO
At the end I show you how to reprogram a vending machine’s NFC tag to contain more credits. With this being 2019, contactless payment is becoming more common with your credit cards/smartphones.In this blog post I will cover some quick basics about NFC, Mifare Classic and how to set up everything for reading and writing a NFC tag. In 2018, my employer started handing out U-KEYs to be used to load funds onto and buy coffee and snacks from different vending machines around the building. MIFARE DESFire: those tags come pre-programmed with a general purpose DESFire operating system which offers a simple directory structure and files, and are the type of MIFARE offering the highest security levels.
MIFARE CRACKER PLUS
The Plus subfamily brings the new level of security up to 128-bit AES encryption.
Most of the time used for regular access badges and has reaaally simple security mechanisms for access control This memory, either 1024 or 4096 bytes, is divided into sectors and blocks.
MIFARE CRACKER SERIES
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.
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.
