Pavel Vovk Hardware Implementation of the ISO7816 Protocol Plastic cards have flooded our world and have significantly changed our understanding of information, its availability and cost. The rapid development of telecommunications, which made a reality not only the petty-bourgeois motto "Internet to every home", but also the cherished idea of money in the form of a piece of plastic for science fiction dreamers of the second half of the 20th century, presented engineers involved in the development of systems for the exchange of confidential information with a rather difficult problem of choosing an elementary hardware platform base for these tasks.

Vladimir Zakharov RFID solutions for the 860 MHz band Currently, solutions based on radio frequency identification (RFID) are becoming more and more relevant in the field of logistics, inventory control, quality control, process automation and many other industries. More and more popular in recent years are RFID solutions in the ultra-high frequency (UHF) range, that is, at frequencies of 862-868 MHz. The popularity is primarily due to two factors: a constant decrease in the price of tags and an exceptionally high range of action - from 0.5 to 12 meters (depending on the type of tag and reader antennas). This article will look at examples of the implementation of RFID systems in various fields.

ADC and DAC
Artem Kozlov, Georgy Korolev Differential measurement methods with delta-sigma ADC Linear Technologies. Part 2 Linear Technologies' sigma-delta ADCs often do not require instrumentation amplifiers. However, if using a single ADC is not enough, a properly applied amplifier will increase the overall system resolution.

Joseph Karshenboim Dual-channel Ethernet controllers - switches KSZ8842 and KSZ8862 Unfortunately, what has more options is not always given free of charge. Quite often you can hear the following question: “We want our device to work over the Internet. What component should be used for this so that the total cost of the product does not increase? " At the same time, we will clarify that we will mainly talk about devices for industrial use, and not about household or office equipment. And one more clarification: the development will be carried out in the style traditional for our developers, that is, by adding new components: microcircuits and passive elements, and not by developing a new specialized microcircuit with new functions.

Cherie De Tomasi Benefits of Using LXI Data Acquisition Instruments LXI or LAN eXtensions for Instruments is the new industry standard for instrumentation. It was developed by a consortium of leading manufacturers and users of test equipment, established in September 2004 and now has over 40 members. LXI Consortiumhttp://www.lxistandard.org/homeIs a not-for-profit organization that includes leading companies in the instrumentation industry, including co-founders Agilent Technologies and other manufacturers such as Tektronix, Rohde&Schwarz, Keithley Instruments, Racal Instruments and Yokogawa. The LXI specification is based on the well-proven Ethernet standard and describes the interoperability of any LXI device, regardless of manufacturer. This makes it possible to use instruments from different manufacturers without fear of compatibility issues and to make measurements quickly and efficiently.
