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,

Mifare Series 7-Security

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 is to use the triple-encryption DES algorithm for key verification (that is, the keys transmitted between the reader and the card are en

Generally, the atqa of Mifare S50 is 0004 H, and that of Mifare s70 is 0002 H. 2. anticollision Loop) When multiple cards enter the reader operation range, the anti-conflict mechanism selects one of them for the operation. If not selected, the system is in idle mode and waits for the next card selection, this process returns the serial number of the selected

Mifare Series 3-card energy source and Data Transmission

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

NXP Mifare S50 Standard IC card-access bit (access bits) analysis

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.
