BARCELONA — As Internet of Things devices become ubiquitous, consumers will someday pay for gas, parking and tolls from their cars without using a credit card or even stepping out of the vehicle.
Technology is also emerging that relies on a person's fingerprints recorded with the wave of a hand to make a payment without a card, smartphone or physical token.
At Mobile World Congress here, financial services company Visa and auto maker Honda showed off the capability to securely pay for parking and gas from a display inside the vehicle. Security for a user's Visa account would be stored, in encrypted form, on what's called a secure element stored on a chip in the cloud or in the car's brain, called the head unit.
"You could even attach dynamic data elements to each transaction," which would add even more security, said Bill Gajda, senior vice president of innovation at Visa, in an interview.
To make a payment for gas or parking, location technology might come into play to identify which parking space or gas pump is being used. Or, a customer might enter a space number or pump number on the dashboard display, with the payment then quickly deducted from the customer's account through a wireless connection.
Visa also demonstrated a secure store payment made by the wave of a person's hand under a payment terminal. The terminal, made by Paris-based Safran Morpho, quickly took an image of the customer's four fingers, then analyzed the fingerprints to associate them securely with a person's credit account. As demonstrated, a store clerk would then have the ability to quickly see the person's face and account information on a monitor. (All of this assumes the customer has previously registered an image of his or her fingerprints and face.)
Safran Morpho also has the ability to verify with an infrared image of the person's fingers if there is blood flowing through the capillaries under the skin to provide proof-of-life, or "live-ness." Proving a customer's fingers are alive, and not a spoof, would matter in remote locations, such as a rural train station, where no clerk was available.

Visa also displayed a variety of near-field communication chips embedded in key fobs and even the cuff of a jacket that can be used to make payments. NFC is being used by Apple Pay and Samsung Pay, among others, in smartphones for quick payments, and adoption rates are steadily rising.
