Cell Phones and a Cashless Society

Using RFID-enabled Cell Phones, Customers Scan Products and Pay for Purchases at Swiss Farm Store

Customers can use Near Field Communication (NFC) cell phones to access the store, obtain product information and pay for purchases.

February 8, 2010

RFID Journal - Farmer-operated stores, which focus on locally produced foods, usually have a minimal staff and often lack a point-of-sale infrastructure, like credit-card terminals. That makes farm stores an ideal experimental setting for an RFID-enabled self-service commerce solution developed by a group of Swiss companies.

The system, which employs passive 13.56 MHz RFID tags compliant with the ISO 14443A standard, as well as RFID-enabled cell phones that support the Near Field Communication (NFC) specifications, is currently being tested at a Swiss farm store near Zurich.


After normal business hours, customers can use the phone's NFC RFID technology to enter the locked store.
"It's more of a community shop," says Alexander Schuemperli, the CEO of e24, the project's organizer.
E24 decided to begin with the farm store after larger retail chains turned it down, indicating that as long as NFC-based contactless payments were not on the same level as credit cards in terms of distribution, the technology wasn't worth trying.
"We could not convince them to use the NFC platform for payments," Schuemperli says.
From the farm store's point of view, however, a system that would enable them to receive credit-card payments without a costly infrastructure was an added attraction.


A sign at the farm store instructs customers about how to use the RFID-enabled system.

Using the phone, customers can scan an RFID tag attached to, say, a bottle of wine, to display such information as which company produced it, and when, then add that item to a "shopping cart" on the phone. (For bulk items such as apples, the tag is included in the product display, and customers are responsible for weighing their produce and entering the amount on the phone.) To read a tag, the phone needs to be placed within a few millimeters of it.

The customer then pays for the desired goods via SIX Multi Solutions' Mobile Buy secure payment service, which links mobile-phone purchases to a Visa or MasterCard credit-card account.

Together with Swisscom, which provided 80 Nokia 6131 mobile phones—the oldest model equipped with NFC technology—e24 recruited customers using a Facebook page and referrals from the store. The participants range from local university students with a passion for mobile technology to retired women.

To shop after the store's normal opening hours—8 a.m. to 6 p.m.—a customer can position his or her phone close to the front door in order to unlock it and enter the store. The ability to shop after hours provided customers with an incentive to sign up for the pilot. Nexperts, a mobile contactless solutions provider based in Hagenberg, Austria, developed all applications on the mobile phone (Java MIDlet and Secure Element Applet).

For some goods, such as apple jelly, customers can use an RFID tag attached to a sign, to display product information and add an item to the phone's shopping-cart application.

LEGIC Identsystems, a designer and manufacturer of 13.56 MHz passive RFID tags and readers, provided the contactless access technology, and SEA supplied the NFC-enabled door lock cylinders.

"It was interesting to learn from the farmer on his shop-opening policies, which then needed to be programmed in the door locks," says LEGIC spokesperson Marcel Brand.
Customers can utilize the NFC card in their cell phone as a secure ID.
"The same phone could also be used to open a locker in the swimming hall," Brand says, "or pay for a coffee at the vending machine, or operate the copy machine."
E24's Schuemperli is working with the University of Applied Sciences Northern Switzerland to gather data on the project, in the hope that it will prove the viability of pay-by-phone systems that incorporate RFID tags.
"Our goal is to spread NFC payments and show our B-to-B customers NFC payments are a possibility," he explains.
The concept is not entirely new. Schuemperli notes that Japanese cell-phone users have been able to pay with their phones for more than four years, using Sony's FeliCa system.

Stefan Vetsch, who manages the farm store near Zurich at which the system is being tested, says the technology is fairly simple to implement, but that significant challenges remain.
"I believe this system can be really interesting," he states. "The technology is really good, I find, but to make more customers aware will take some time."

iPhone App Helps You Track Your Family

February 5, 2010

Vator - To antsy parents everywhere: your day has come.

AT&T today announced the availability of a new app for the iPhone called FamilyMap, which allows users to track their family members' location on the smartphone.

For $9.99/month you can track up to two phones and for $14.99/month you can track up to five phones. The tracked phones don't even need to be iPhones or other GPS-enabled devices; this service will track most AT&T phones, even if it just uses data from the nearest cellphone tower.

Basically, the app displays a map with an estimation within some small radius of the location of the family member you're searching for. This interactive map displays landmarks like schools and parks and can be switched between satellite mode and interactive street mode.

These features had previously been available only through a desktop version of FamilyMap.

The iPhone version also comes packaged with a bunch of features like Schedule Checks, which appears to be nothing more than a glorified calendar system, and My Places, which allows users to input key locations into the app for remembering later.

Naturally, tracked phones must be on the same billing account as the phone doing the tracking.

AT&T has provided this service since spring 2009 as a means of providing parents with "peace of mind," and the latest port to the iPhone means that they haven't lost interest in this new high-tech form of parenting.
