example to abuse, hack or trick a system which the reader does not have specific authorizations to such as ticketing systems, public transport, University/ISIC cards, building Access systems or whatsoever systems using Mifare classic as core technology) Notes: This article contain no original research. All the research and implementation was made by other people and communities and is publicly available. We made this two cents just for fun and bec

The previous example describes the general steps for detecting and reading and writing NFC tags. This example describes the common Mifare tags. The Mifare Tag can be 1 K, 2 K, and 4 K. The memory partition is similar, and the memory distribution of the 1 K-byte Tag is given: Data is divided into 16 segments, each with 4 blocks. Each Block can store 16 bytes of data. The size is 16X4X16 = 1024 bytes. The la

Phillips's Mifare card is widely used in the market due to its high security. For example, we use bus cards, meal cards for schools and corporate canteens, etc. each slice has an independent key (six-byte password). During communication, the key must be verified before data can be read and written. its key technology i

. Let's talk about the common solutions for RF cards: Phillips's Mifare, Sony's felica, and PBOC of the Chinese name bank. Mifare card has many versions (see http://en.wikipedia.org/wiki/MIFARE for details), common versions include Mifare classic and Mifare desfire, which a

0x00 Preface I have always wanted to play wireless security, but wangcai said that the threshold is low (where is it low? =. = Web dog: I am stupid, Wang). I started ACR122u and wanted to get into trouble from NFC. Now I have read this article to popularize basic knowledge. Mifare Classic card provides 1-4 k capacity. We often see the Mifare Classic 1 k (S50), the so-called M1 card. The M1 card has 16 secto

Label:The Mifare S50 standard IC card has a 1 K-byte EEPROM, which is used primarily to store data and control information. The 1-byte EEPROM is divided into 16 zones, each divided into 4 segments, with 16 bytes in each of the 1 segments. The last segment of each zone is called "tail" (trailer), which includes two keys and the access conditions (programmable) for each segment in the zone.

In the Mifare card, energy and data are transmitted through an antenna. The antenna in the card contains several turns of coils and is directly connected to the chip without additional components. The coil is embedded in plastic to form a passive non-contact card. The card reader sends a set of Fixed-frequency electromagnetic waves to the IC. The card contains an IC series resonance circuit, which is the same as the frequency of the reader. In this w

The Mifare IC chip contains the EEPROM, rfinterface, and digital control unit. 1. rfrf Interface Rfrf interface circuits mainly include waveform conversion modules. It can receive the 13.56mhz radio modulation frequency on the card reader. On the one hand, it sends the modulation/Demodulation module, and on the other hand it converts the waveform, converts the sine wave into a square wave, and then rectifies and filters it, the voltage control modul

speed up!4)The anti-conflict of typea requires a relatively high and accurate timing sequence on the card. Therefore, you need to add hardware to the card and reader separately, while the anti-conflict of typeB can be implemented by software. From the comparison above, we can see that the two technologies are difficult to say that they are superior or inferior, which is one of the reasons why the international ISO organization has determined the two standards. However, for public transit syste

In a review by Anandtech, it was found that the Nexus 4 makes use of the Broadcom BCM20793 NFC controller. all previous NFC-enabled Nexus devices (Nexus S, Galaxy Nexus, Nexus Q and Nexus 7), as well as the vast majority of non-Nexus Android phones,

First look at the definitions of the various keys: Super Key: An attribute set that uniquely identifies a tuple in a relationship is called a super key for a relational pattern candidate Keys (Candidate key): A key that does not contain extra attributes is called a candidate key
