RFID technologies are commonly used for logistics initiatives. However, having less universal frequency standards across all countries challenges globaNFC CARDimplementations.
In the internal process like copper refining the frequencies are restricted with an environment controlled by BHP Billiton. In this particular environment, combo cards was supposed to track and trace cathode performance effectively, provided that we've got the technology could survive harsh conditions.
CSC and BHP Billiton tested great and bad contactless cards within the company's Cerro Colorado tank house, inside a hostile environment that included acid mist in mid-air, water temperatures of 190 degrees Fahrenheit and short-circuiting.
Ahead of the study, damaged metal cathodes, combo cards employed in the refining tactic to extract copper, produced a reduced grade of copper. This is costly to BHP Billiton, the world's largest diversified resource company.
10 % with the copper created in BHP Billiton's Chile-based Cerro Colorado mine alone could be off-grade, causing decreased revenue and increased cost to rfid inlay manually separate contaminated copper. The plates were visually inspected, but there wasn't any method to identify and track individual plates because identifying technologies including bar codes couldn't withstand the acid corrosion.
BHP wished to explore whether RFID CARDtechnology, which utilizes tags and readers to follow people or objects via radio wave transmissions, could track the plates. In accordance with Dennis Franklin, account executive for CSC's Australian Resources Sector, "If RFID could be utilized to increase quality, BHP could demand more of an premium available."

A lot of companies use proximity cards to control physical access. A staff holds their rfid inlay within a few inches in the reader people receives a unique id from your card and transmits it to many central computer that tells it if you should open the threshold.
This can be rather magical, considering that the tag is credit card-thin and possesses no battery. The key comes to forsmart cards. The various readers constantly transmits a rather strong carrier the tag derives its power and clock out of this carrier, kind of like a crystal radio. The tag changes simply how much carrier it reflects back on the reader%u2014loosely, celebrate the circuit across its antenna similar to a quick or more as an open%u2014to transmit its code. The various readers and also the tag both have antenna coils tuned towards the carrier frequency they work just like a loosely-coupled resonant transformer.
Or otherwise that's the thought. I couldn't find any credible documentation for the protocol employed by the particular proximity cards which are accessible to me (Motorola's Flexpass). I did find a datasheet that claimed that they can dealt with a contactless cardsr. I wound a couple dozen turns of magnet wire over a 4" form, taped it into a reader, and 'scoped the coil. There was clearly indeed a 125 kHz sine wave, large, a couple of volts peak to peak. They did, a minimum of, work at 125 kHz.
Enjoyrfid, a respected NFC CARD technology products manufacturer, has recently unveiled the most recent RFID card reader which is perfect for those RFID applications asking for longer read range and also accuracy. With all the top RFID technology, the part of RFID reader from DALIY has become among more important part in access control system.
Simply take one example, UHF Long Range Reader - DL920, a combo cards reader released by enjoyrfid, has the long reading range from 8m to 15m (tag and environment dependent) along with a fast read speed of reading one particular card is under 10ms per 64 bits typically, which shows great performance in reader environment because of compliant with ISO18000-6B or ISO18000-6CEPC Gen2 standard. Using the UHF technology, this RFID card reader has stable identification performance of operating from ISM 902MHz to 928MHz or from 920MHz to 925MHz.
In general, the RFID card reader has been utilized in variety contactless cards applications getting longer read range and accuracy, like parking management system, access control system and warehouse management system. Currently, the RFID card reader from enjoyrfid has the inexpensive effective with great performance, which is among the best choice towards the commercial industries.
Enjoyrfid, announced the general use of the SDiD 1212 Low Frequency (LF) RFID Reader Files. Oahu is the first RFID CARD Files with embedded 512MB SD memory in the marketplace.
In addition to the Low Frequency RFID read and write functions, SDiD 1212 can store user applications and knowledge. This true plug-and-play rfid inlay Files can be configured to right away load drivers and launch applications that greatly increase the portability and easy installation. By inserting the SDiD 1212 into the SD slot of an Smartphone or PDA, the integrated device can be used for most low-frequency RFID applications such as asset tracking, field services, work-flow control, logistics, pet and livestock animal identification. RFID tag data transactions might be processed in real time through mobile connections such as Wi-Fi, CDMA, GSM / GPRS or UMTS from the portable device.
The SDiD 1212 combo cards Files is capable of doing interrogating most 125 kHz and 134.2 kHz RFID tag formats including: TI TIRIS, NXP Hitag, Q5, EM4100 series, and ISO 11784 / ISO 11785 half-duplex (HDX) and full-duplex (FDX). System integrators can readily create custom applications through the use of the available Software Development Kit (SDK) which is compatible with PocketPC 2002/2003, Windows Mobile 2003, Windows Mobile 5. and Windows Mobile 6. Os.
