Wearables are a clear evolution of the mobile wallet, but companies are still experimenting with use cases. Here are a few of the latest concepts.
The Token payment ring
Function over form
Visa, Mastercard and others have sought to address this by working with fashion designers to make their payment rings more stylish. The startup Token, however, is pushing in the opposite direction by launching a chunky, utilitarian ring that goes overboard on what it can do for the wearer.

The approach is reminiscent of Amazon's Echo devices, which are bland monolithic speakers that can be loaded with "skills" to enable them to place calls, make purchases, activate light switches and tell jokes.

Even in Token's promotional photos, the ring is a hefty lump of metal that dwarfs the model's wedding band. But what Token's ring lacks in beauty, it makes up for in brains.

Token is working with card networks, mass transit agencies and providers of both physical and digital security to develop a biometrically activated ‘swiss army knife’ of RFID connectivity. Out of the gate, Token is designed with multiple functions such as password storage; physical access to buildings, cars and networks; and interoperability with NFC enabled payment cards and mass transit networks.
Universal theme parks
'Universal' acceptance
Universal Resort's launch of the TapuTapu band at its new Volcano Bay water park illustrates how much more a wearable can do when it is incorporated into the design of the park from the get-go.

The park has been designed to accept TapuTapu wristband payments for admittance, food and souvenirs, but also to participate in the "virtual line" service, in which patrons can reserve a spot in line at a particular ride and the band will vibrate when it is time for their turn.

Hersheypark was one of the first theme parks to test contactless payment wristbands in 2012, but dropped its use a year later when reporting that the "Easy Pay" program was not resonating with park visitors.

Hersheypark's failing might have been that its band was not fully integrated into the park experience; it was little more than a wearable prepaid card. Walt Disney Co. launched its more ambitious "Magic Bands" around the same time Hersheypark was ditching its technology, but expanded the use case to enable the bands to unlock hotel room doors and provide theme park admittance. Disney also turned its bands into a souvenir; it lets patrons keep the bands after they leave, and customize them with buttons depicting Disney characters and attractions.

Like Universal's TapuTapu, Disney also allows Magic Band users to skip long lines through the Disney FastPass+ system.

But while Disney's wearable still resembles a simple bracelet, Universal's TapuTapu has the look and feel of a smartwatch, giving visitors notifications and alerts related to happenings in the park, deals at restaurants, and alerts about the patron's place in a virtual line.
Looking cool
With its WaveShades, Visa engages in a delicate balancing act of making its new payment wearable cool and trendy as any other fashion accessory without invoking the geekiness of the ill-fated Google Glass.

In a partnership with sunglasses manufacturer Local Supply and wearable fintech provider Inamo, Visa's WaveShades initiate contactless payments through a chip in the arm of the glasses. In choosing Inamo as a partner, Visa will operate WaveShades on the same payment platform that the Australian company developed last year called Inamo Curl, a waterproof wearable band designed for beach lovers and surfers.

Oberthur Technologies is providing the tech behind the contactless sunglasses, while Heritage Bank will serve as the authorized deposit-taking institution in Australia.

Visa is banking on WaveShades to fit more easily into the mainstream than Google's far more high tech project.

From about late 2013 to early 2015, Google experimented with payment options for Google Glass, its eyewear accessory designed for various tasks from accepting messages to omnichannel services and, ultimately, contactless or voice-enabled payments.

When first unveiled, Google sold Google Glass only to early adopters, some of which worked at mobile payments or loyalty service providers like LevelUp.

Even as some companies continued to show an interest in the high-tech wearable, Google finally pulled the plug on its experiment and quit selling the Google Glass in early 2015. Critics considered the device too expensive and too geeky to be a mainstream success.
Need for speed
In-app payments via Apple Pay have been available with the ExxonMobil Speedpass+ app since last year, but in April the petroleum giant boosted the app to enable users to pay at the pump at 9,600 U.S. Exxon and Mobil stations via the Apple Watch.

Users who have already downloaded the Speedpass+ app may select a pump number first and complete payment using the Apple Watch—even if the terminal lacks Near Field Communication technology—based on an update launched April 27 in the App Store.

With the Speedpass+ update, iPhone users also may log in to the app with Touch ID.

Speedpass dates back to 1997, when it operated as a wireless keyfob that motorists used to pay for fuel. The latest version, Speedpass+, is an app-based payment system that debuted in March of last year and now works at 90% of ExxonMobil's more than 11,000 stations nationwide.

Big on authentication
In an increasingly digital world, retailers are working to bring transactions closer to the shopper and further away from traditional hardware.

Biowatch brings that trend about as close to the shopper as possible, with a product that can be used once to provide authentication for multiple services.

"The 'things' connected to the Internet do not have a way to authenticate the human being interacting with them," said Matthias Vanoni, cofounder and CEO of Biowatch, a Lausanne, Switzerland startup that uses vein recognition technology to authenticate people for a variety of purposes. "But the 'things' can recognize a device like a wearable. Biowatch's recognition of the wearable means recognizing the human being behind that."

Biowatch has been gradually attracting attention since its founding two years ago. It recently drew a $1.2 million seed round and a cash stipend of about $35,000 for winning a Visa developer contest at the recent Mobile World Congress, a prize that comes with a significant boost to the startup's visibility and reputation.

"Visa will be useful to increase our credibility towards partners and thus accelerate product development," Vanoni said. "That will allow us to integrate more easily into bank applications worldwide."
A fitness tracker and smartphone
Pocket change
Samsung, terminal manufacturer Ingenico and Swiss app developer Smartlink are teaming up on an odd premise: Rather than treat wearables as vessels for a mobile wallet, treat those devices as a handful of bills and coins.

The use cases for such a system include consumers going for a run or a spa visit where having a phone is not otherwise necessary, but there is still a need to spend a few bucks on a bottle of water or other small items.

This concept led the tech companies to form the Contactless Companion Platform, which is in testing in countries across North America, Europe and Africa. The testing is expected to continue into September 2017.

The companies built the CCP on the premise that Near Field Communication technology for contactless payments could be used to treat wearables as stored-value containers managed by an app. The platform would provide access to a small amount of money and for a limited time period.

The payments industry has often tested this model without considering it to be the end goal. Many early contactless and mobile payment pilots were limited to festivals, stadium events and short-term programs like the Olympics.
Android Pay app
Designer fashion
Consumers who prefer fancy designer watches will soon have the option to add contactless payments to their bling, as Movado Group rolls out a crop of stylish watches with Android Pay built in.

Movado Group is partnering with Google for Movado Connect, a collection of five new men’s smartwatches featuring Android Wear 2.0 with payment capabilities to be unveiled later this month at Baselworld, the high-end jewelry and watch show in Switzerland.

Designer brands in Movado’s new line include styles from Hugo Boss and Tommy Hilfiger, the company said in the release. Prices will start at $495 for watches rolling out this fall.

Electronics companies including South Korea’s LG and China’s Huawei previously announced smartwatches featuring Android Pay.
