![]() ![]() NXP did just this, with the MIFARE Plus card, by introducing a card which works with all existing Mifare Classic readers, but was not vulnerable to attacks on traditional MIFARE Classic cards. In these cases manufacturers (NXP) are tasked with coming up with quick fixes to address these issues, or they run the risk of losing large scale customers, like city bus or metro passes and readers. In some cases (like in a city wide transportation infrastructure) this may take years to implement and have prohibitively high costs. For example, if moving from a MIFARE Classic card type to a MIFARE DESfire smart card, which uses well-vetted AES encryption, the card readers also have to be updated to support AES as well. ![]() They rely on the fact that the vulnerability costs more to implement, in time or money, than traditional attacks such as just breaking a window or paying a disgruntled employee for information.Ĭost is usually the largest factor. What happens when something so widespread and embedded into a corporate or city infrastructure is revealed to have a custom cryptography algorithm and it’s predictable? After the initial panic, most companies realize that it’s not financially feasible to fix this security issue for years to come, if at all. One of the main players in this industry, NXP, designed the MIFARE Classic many years ago, and to date 260 Million readers and 10 billion card components have been sold in the MIFARE family of products. The MIFARE product-based card may also remain in the wallet during the transaction, even if there are coins in it.Smart cards and the use of near-field communications (NFC) is an increasingly popular tool for many things from wireless payment solutions to entry access and identification. Thus, the MF1ICS50 card user is not forced to stop at the reader leading to high throughput at gates and reduced boarding times onto buses. Which could allow complete ticketing transactions to be handled in less than 100 ms. The MF1ICS50 is designed for simple integration and user convenience. The anti-collision algorithm selects each card individually and ensures that the execution of a transaction with a selected card is performed correctly without data corruption resulting from other cards in the field. The MIFARE MF1ICS50 IC is used in applications like public transport ticketing where major cities have adopted MIFARE as their e-ticketing solution of choice.Īn intelligent anti-collision function allows operating more than one card in the field simultaneously. NXP ® has developed the MIFARE ® MF1ICS50 to be used in a contactless smart card according to ISO/IEC 14443 Type-A. ![]()
