NFC Technology beyond Mobile Payments

Technology: Near Field Communication (NFC) is a short-range, high-frequency (13.56 MHz) wireless technology, typically requiring a distance of 4cm or less to initiate a connection. NFC allows you to share small payloads of data between an NFC tag and a mobile device (Android, iOS or Windows phone), or between two mobile devices. Tags can range in complexity. Simple tags offer just read and write semantics, sometimes with one-time-programmable areas to make the card read-only. More complex tags offer math operations, and have cryptographic hardware to authenticate access to a sector. The most sophisticated tags contain operating environments, allowing complex interactions with code executing on the tag. The data stored in the tag can be written in a variety of formats, e.g. many of the Android framework APIs are based around a NFC Forum standard called NDEF (NFC Data Exchange Format). Application Expansion: NFC technology was originally developed and promoted as a highly secure technology to enable mobile payments and ticketing applications, enabling consumers to make payments by merely tapping their cellular device against an NFC-enabled payment terminal to conduct a transaction. More recently it has also been making major inroads in the industrial world as well. Texas Instruments recently announced that it has released what it says is “the first highly integrated NFC sensor transponder for industrial, medical, wearable and Internet of Things (IoT) applications.” An important aspect of this technology is its versatility as it is not only used for making payments but also for data sharing, reading information from smart posters, and providing authentication wherever required. Industrial control applications for NFC includes use in devices that require an analog or digital interface, data-logging capabilities and data transfers to an NFC-enabled reader, such as Access Controls, Configuration of Industrial Equipment, Machines, Lab Equipment, eMetering, Smart Homes etc. The emergence of smart manufacturing facilities is creating a new level of automation in the factory, with intelligent object networking, independent process manufacturing, and frequent use of interactions between the real and virtual worlds. These trends are changing how manufacturers manage their production networks, and making it possible to operate in what is almost real time. Near Field Communication has an important role to play in this new environment, because NFC helps reduce the time it takes to process items, can enable customization at any point in the production process, and simplifies logistics.

RoHS Recast

A growing number of regions and countries are implementing RoHS (Restriction of Hazardous Substances) legislation or are in the process. This directive restricts the use of certain hazardous substances in electrical and electronic equipment. RoHS 2 which became a directive (2011/65/EU) in July 2011 and took effect on 2nd January 2013 is an evolution of the original RoHS directive (2002/95/EC). RoHS 2 broadens the scope of the original directive to include additional products and product categories. In short, RoHS 2 is transitioning to an “open scope” Directive which will be completed by 2017. It broadens the original RoHS (2002/95/EC) scope to include additional products and product categories and makes RoHS 2 compliance a CE directive thus placing more data collection, test, verification and documentation burden on companies throughout the entire supply chain. Compliance with the new RoHS 2 Directive is required before you can place a CE mark on your products. This should be obvious on your Declaration of Conformity – Bottom line is going to cost a lot of money! Unlike the original RoHS directive few products and product categories are excluded. RoHS 2 applies to all EEE products including cables and spare parts that are “dependent on electric current or electromagnetic fields for at least one intended function”. The only equipment and products permanently excluded or exempt are military equipment, space equipment and equipment designed to be part of another piece of equipment falling outside the scope of RoHS. The time is running short for meeting the 22nd July 2017 deadline for Industrial Monitoring and Control Product RoHS 2 compliance. Oaces , your partner in Product and Component Engineering Services, through our understanding of RoHS, CE and EU Directives along with other relevant standards can help manufacturers comply within the stipulated time frame. While RoHS2 is not an immediate requirement for manufacturers selling in North America it is only a matter of time before it will be required. States like California have been in the forefront to adopt such directives as was evident in case of Power Supply emissions and efficiency standards.
