Near-field Communication
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s. The NFC Forum has helped define and promote the technology, setting standards for certifying device compliance. Secure communications are available by applying encryption algorithms as is done for credit cards and if they fit the criteria for being considered a personal area network. ...

GSMA
The GSM Association (GSMA) is a Nonprofit organization, non-profit trade association that represents the interests of mobile network operators worldwide. More than 750 mobile operators are full GSMA members and a further 400 companies in the broader mobile ecosystem are associate members. History The GSMA was formed in 1995 as the GSM MoU Association as a body to support and promote mobile operators using the GSM (Global System for Mobile communications) standard for cellular networks. It traces its history back to a memorandum of understanding signed in 1987 by 13 operators in 12 countries that committed to deploying GSM for mobile services. Membership and governance Full membership of the GSMA is open to licensed mobile operators using a GSM family technology. Approximately 750 such operators around the world are full GSMA members. Associate membership of the GSMA is open to non-operator companies active in the mobile ecosystem. These include handset and device makers, ...

Barcode
A barcode or bar code is a method of representing data in a visual, Machine-readable data, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called ''2D barcodes'' or ''matrix codes'', although they do not use bars as such. Both can be read using purpose-built 2D optical scanners, which exist in a few different forms. Matrix codes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the code. A mobile device with a built-in camera, such as a smartphone, can function as the latter type of barcode reader usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asset Tracking
Asset tracking refers to the method of tracking physical assets, either by scanning barcode labels attached to the assets or by using tags using GPS, BLE, LoRa, or RFID which broadcast their location. These technologies can also be used for indoor tracking of persons wearing a tag. RFID 'Passive' RFID tags broadcast their location but have limited transmission range (typically a few meters). Longer-range "smart tags" use 'active' RFID -where a radio transmitter is powered by a battery and can transmit up to 2000 meters (6,600 feet) in optimum conditions. RFID-based Asset Tracking requires an infrastructure to be put in place before the whereabouts of tags may be ascertained. An asset tracking system can record the location and usage of the assets and generate various reports. Unlike traditional barcode labels, RFID tags can be read faster and have higher durability. RFID is integrated in smart warehousing to track inventory and other assets. Realtime information of the tagged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Power Consortium
The Wireless Power Consortium (WPC) is a Multinational corporation, multinational technology consortium formed on December 17, 2008. WPC is a virtual corporation with administrative offices in Washington, DC. Its mission is to create and promote global adoption of its interface standards: Qi (standard), Qi for small, mobile electronics, and Ki for wireless power in the kitchen. It is an open membership of Asian, European, and American companies, working toward the global standardization of wireless charging technology. The Wireless Power Consortium was started by Fulton Innovation, a 100% subsidiary of Alticor, parent company of Amway. The original motivation was to power a portable water purifier, sold by Amway, called eSpring, for which the wireless power transfer technology called eCoupled was created. On Nov 26, 2008 Fulton Innovation released "The Base Spec: Low Power Specification Guide for Partnered Product Development, Revision 0.9". Buoyed by the acquired intellectual pr ...
