NFC: Tips and Tricks

Benefits of NFC: Tips and Tricks


Near Field Communication (NFC) and wireless touch-to-transfer technologies have been much talked about recently, especially as they promise to be the future of on-the-go payments in businesses, transport, and many other options.
But according to the experts, NFC is about to blow our minds with new applications outside the retail world. Nowadays, there are many NFC-enabled smartphones that allow users to make payments and obtain discounts and offers while they shop, or even to pay for transport on cities. But here are some other uses of NFC technology that we may see :

Social networking is one of the fields where NFC technology can make a difference, changing the way we conceive social activities today, like for instance sharing photos by simply putting one device next to another, or accessing movie information from posters.
Contactless payments when shopping are something that is already well accepted today, and some retailers are even experimenting with NFC self-checkout programs. But what if we could get more out of the products sitting on the shelves when we go shopping? ‘smart products’ could give us a lot more information about them with a simple scanning.
When we travel, we can benefit from NFC technologies using our phone as a wallet, but also to find information about historical places, restaurants, shopping centers, transport, discounts, etc.

NFC will allow patients to carry their medical history with them wherever they go. So they’ll be able to manage their doctor’s appointments, share test results, etc. Also, it’ll be an advantage when they travel to a different country and they have to go to a hospital but don’t speak the language.
Smartphones and cars will be connected through NFC to open doors, control the GPS system, activate driving aids, receive data and alerts about the state of the roads or pay for the petrol, among other things.
NFC can also improve marketing as we know it. By adding NFC stickers to mailing, marketers could improve considerably the reach of their advertising campaigns.
All of this sounds great. But it may be a while until all of these functionalities are fully implemented, as not all devices implement NFC. Apple, for one, doesn’t. Although there are rumours that say that the next iPhone will include an e-wallet. Another problem to consider is consumer education, as people don’t trust NFC due to privacy and security issues.

Continental is testing its electronic key for the rental of cars in an ongoing trial in Bordeaux in France. Via an application for smartphones will be able to book a car and get on your smartphone NFC key in an encrypted format .
At this point you can start the car using your smartphone NFC and also to reserve a parking spot for recharging electric vehicles.
The service is still in testing phase but allows users to book their car hire and even a few moments before you start it in a few moments.

Use PKE And NFC To Unlock The Automotive Market

NFC

NFC is a short-range wireless technology that facilitates the secure exchange of data. It is being increasingly adopted for secure transactions, including use by mobile phone manufacturers to create an “electronic wallet.” NFC combined with an embedded secure element offers consumers a high level of convenience, interactivity, and security with their mobile devices. It operates at 13.56 MHz at rates ranging from 106 to 424 kbits/s, so NFC-enabled smart phones could be used for RKE functions.

3. NFC-enabled RKE systems potentially could enable smart phones with NFC to be used for car access functions.

NFC communication involves an initiator and a target. To transmit data between two NFC interfaces, one NFC interface activates its transmitter and works as an NFC initiator. The high-frequency current that flows in the antenna induces a magnetic field that spreads around the antenna loop and moves through the antenna loop of the other NFC interface located close by. A voltage is then induced in the antenna loop of the other NFC interface, which detects the voltage with its receiver. 
If the NFC interface receives signals and the corresponding commands of an NFC initiator, this NFC interface automatically adopts the role of an NFC target. For data transmission between the NFC interfaces, the amplitude of the emitted alternating field is modulated (amplitude shift keying, or ASK, modulation). The transmission direction is reversed to send data from the NFC target to the NFC initiator. If an NFC interface is located close to a compatible RFID reader, the NFC interface adopts the role of an NFC target and can transmit data to the reader using load modulation. This mode is called “card emulation mode.”
An NFC interface also can communicate with compatible passive transponders. The interface can supply these transponders with power, and these transponders can transmit data back to the NFC interface via load modulation. In this case, the NFC interface adopts the role of a radio-frequency identification (RFID) reader.
NFC can be used for car access if a reader is installed in a way that it is accessible from outside the car (e.g., located in the side mirror). This is particularly helpful in communities that share cars or other situations where different people have access to a number of cars (e.g., company car fleets).
ICs are available for RKE, PKE, and NFC applications. For example, the Melexis MLX90132 was designed and qualified for automotive systems, making it robust and durable in retail, consumer, and industrial NFC applications (Fig. 4). This 13.56-MHz, fully integrated, multi-protocol RFID/NFC transceiver IC supports ISO/IEC protocols 18092, 14443A and B, 15693, and 18000-3.

4. The Melexis MLX90132 NFC transceiver includes the 125-kHz RFID transceiver and the 13.56-MHz NFC transceiver.

The MLX90132 handles subcarrier frequencies from 106 to 848 kHz and baud rates up to 848 kbits/s. Its digital section handles the low protocol layers from the application programming interface (API) to the physical layer (PHY) using advanced bit and frame decoding functions. The IC embeds tag emulation functionality for NFC support. Enhanced tag and field detection capabilities significantly reduce power consumption in RFID reader configuration and in NFC mode.

London Underground to accept NFC payments

A London Underground tube train passes through a station
Users of mobile network operator EE’s Cash on Tap NFC payments service will be able to use their mobile phone to pay for travel on the London Underground, Docklands Light Railway and London Overground services from 16 September, when Transport for London (TfL) introduces the ability for passengers topay for travel using contactless cards.
“The extension of Cash on Tap to TfL’s transport network will mean no more queuing to top-up an Oyster card, or rummaging around a handbag first thing in the morning,” EE says. “Cash on Tap will also avoid the issue of card clash — where gates may not open if customers have more than one contactless card in their purse or wallet.”
“The service will use EE’s free Cash on Tap mobile contactless payment service app, which is due to be compatible with over 500,000 customers’ handsets this year. There will be no added charges for using Cash on Tap to pay for travel, and both daily and weekly caps ensure customers won’t pay a penny more than using an Oyster card.”
“Customers won’t pay a penny more than using an Oyster card”
Contactless payments were introduced on London’s bus network in December 2012, giving passengers the option of paying for travel with open loop contactless cards in addition to the existing prepaid Oyster cards issued by TfL. 825,000 passengers have used the service to pay for 17m bus journeys so far and around 65,000 journeys a day are currently paid for with a contactless card. The extension of contactless payments to the London Underground has been undergoing pilot testing since April 2014.
“The new option, which is part of a huge range of improvements TfL is making for customers, means that there will no longer be any need to spend time topping up Oyster balances because fares are charged directly to payment card accounts,” TfL says.
“Contactless payments — credit, debit, charge or prepaid cards or devices — work in the same way as Oyster, charging the pay-as-you-go fare by touching in and out on the readers at the start and end of every journey.
“In addition to daily capping, a new Monday to Sunday cap will also apply for customers using the contactless payment option, as TfL’s advanced system will automatically calculate the best value contactless fare over the course of the week.
“Only one charge per day will be sent to the bank or financial provider for payment”
“Only one charge per day will be sent to the bank or financial provider for payment — clearly referencing it as a payment to TfL for travel. Registered customers will be able to easily view their journey and payment history via their TfL online account.
“The account, part of TfL’s work to modernise and personalise the services that it offers customers, ensures ease and transparency and also gives customers the ability to obtain refunds on incomplete journeys.”
“TfL is continuing to remind customers that it is imperative that they only touch one card to the reader to avoid ‘card clash’,” the transport operator adds. “This simple measure will ensure customers avoid paying with a card they did not intend to use. It will also avoid gates not opening or not giving a green light to proceed.”
“If a reader at a station detects a contactless payment card and an Oyster card together, it will reject both and the gates will not open. Once the system is launched, if a wallet or purse containing a number of cards is touched on the yellow reader it is possible that the reader could detect one card without seeing the other and a card that the customers did not intend to pay with could be charged.”
“TfL and National Rail continue to work together to develop the programme to expand the system to the suburban rail routes where Oyster is currently accepted.”

GSMA publishes NFC coupon and loyalty technical proposal

The GSMA has published Mobile Commerce, NFC Coupons and Loyalty Acceptance, a technical proposal based on open standards that aims to provide “the tools, knowledge and methodology for mobile operators and the wider retail ecosystem to work together to develop a consistent approach to mobile loyalty and couponing”.
GSMA
The technical architecture described in the document is designed for use with NFC SIMs issued by carriers, based on the GS1 digital coupon management standard.
“A consistent approach will generate economies of scale across the value chain,” the GSMA explains. “Similarly, the use of open standards for technical delivery can engender consistency and simplicity, helping extend the reach of loyalty programmes and generate scale.
“Until now, there has been no single, common, open specification for a digital platform that combines offers, coupons and loyalty to form an interoperable end-to-end solution; beneficial to merchants, manufacturers and wider service provider ecosystems.
“This document bridges that gap as it outlines an architecture model and the component interfaces that can be adopted to produce a common approach for coupon and loyalty transactions using mobile handsets.”

Consumers shop more on smartphones

News in brief
“Nearly all mobile payments growth on Adyen’s platform in Q2 originated from smartphones,” the payments processor’s latest globalMobile Payments Index has found. “Europe leads the world in mcommerce transactions, with 22.7% of all transactions originating from a mobile device (12.4% phone; 10.3% tablet). This represents a near 40% increase from June 2013, when mobile represented 16.3% of total transactions.”
