NFC Release 15 quadruples contactless range for faster, easier tap-to-pay

Why it matters: If you get anxiety about trying to line your device up with a terminal to make a contactless payment, here's some good news: the NFC Forum has announced that version 15 of the standard is quadrupling the distance of contactless connections, from the current 0.5 cm (0.19 inches) to 2 cm (0.78 inches). Anyone who knows the struggle of trying to line up a device, especially a smartwatch, with a payment terminal will be relieved to know that the range, also known as the operating vo

Upcoming NFC Release 15 quadruples contactless range, making tap-to-pay faster and easier

Proofs Without Words

The following demonstrate proofs of various identities and theorems using pictures, inspired from this gallery. Nichomauss' Theorem: the sum of the first cubes can be written as the square of the sum of the first integers, a statement that can be written as . Here, we use the same re-arrangement as the first proof on this page (the sum of first odd integers is a square). Here's another re-arrangement to see this: This also suggests the following alternative proof:

NFC just got a serious range boost, and your next smartwatch is going to love it

Edgar Cervantes / Android Authority TL;DR The new NFC Release 15 specification increases range from 5mm to up to 2cm, making alignment less critical to initiating a compliant connection. This extended range will make NFC connections quicker and more reliable in the future, especially for smaller devices like smart watches and smart rings. It also introduces support for the NFC Digital Product Passport (NDPP), allowing phones to serve as payment terminals. Unless you’re picking up something i

Kia EV4 Review: Price, Specs, Availability

The 2026 Kia EV4 could be an important vehicle in the ongoing global EV transition. To be sold in 140 markets globally, the EV4 is a carefully calibrated shot at bringing long-range electric power into the high-volume mainstream segment of compact sedans and hatchbacks at an affordable price. US and Asian markets will get an EV4 sedan (the model I spent the day with for this review), now built in Korea. Europeans’ preference for five-doors means only an EV4 hatchback will be available in that r

What to read this weekend: Vampires and more vampires

I was pretty late in getting to this one, as it's been on my list for a good while now, but I really can't think of a better time to have finally picked up this retelling of the original sapphic vampire story, Carmilla, than during Pride Month. And what a treat it is. Hungerstone is a gothic novel that follows Lenore, a woman who has been uprooted from London and moved to the British moorlands by her husband, Henry, to fulfill his career ambitions. Henry is… not the best, and Lenore could defini

Tesla's new Model S and X vehicles are now available in the US

Tesla has officially launched new versions of the Model S and the Model X in the US. As Electrek notes, however, the upgrades may not be quite as big or compelling as one could hope when the vehicles now cost $5,000 more. The automaker has posted a list of updates for the vehicles on X, including a new Frost Blue paint color option and a range of up to 410 miles for the Model S Long Range version, which is Tesla's longest range yet. Getting the Frost Blue paint will cost buyers $2,500 more, howe

Star Trek: Strange New Worlds is getting a fifth and final season

We’re still over a month away from the premiere of season three, but Paramount has announced that Star Trek: Strange New Worlds is getting a fifth season — and that it will be its last. While Strange New Worlds’ first four seasons are (or will be) all ten episodes long, the fifth will run for just six. Still, executive producers Akiva Goldsman, Henry Alonso Myers, and Alex Kurtzman said in a joint statement that they’ll “complete our five-season mission, just as we envisioned it.” “From the ve

Star Trek: Strange New Worlds will end with a truncated fifth season

Star Trek: Strange New Worlds will only visit around 26 strange new worlds before shuttling into that cancellation sunset. The show will end with a truncated fifth season of six episodes, according to reporting by Deadline . This news is relatively surprising, given that Strange New Worlds seems like the most popular and successful show of the modern era. However, not a single newer Trek series has made it past five seasons, so maybe that's just the way things go now. It's worth remembering tha

David Harbour Is More Than Ready for ‘Stranger Things’ to Be Over

David Harbour has been acting professionally for over two decades—he was nominated for a Tony in 2005—but his big break came with Stranger Things. Harbour’s portrayal of Sheriff Jim Hopper immediately endeared him to viewers, and over the show’s run we’ve seen Hawkins, Indiana’s top cop morph from boozy sad sack to strict but loving dad to supernatural beastie-fighting hero to Siberian prison escapee, plus a little romantic tension with Winona Ryder’s character on the side. And since Stranger T

Which iPhone 16 Model Should You Buy?

In a surprising twist, Apple has expanded the iPhone 16 range months after launch with the new iPhone 16e. Unlike the iPhone SE it replaced, the iPhone 16e is a part of the “iPhone 16 family,” according to Tim Cook. That means you have a staggering five different iPhone 16 models to choose from: iPhone 16e, iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max, and they range from $599 unlocked to $1,199. If you're planning to upgrade and aren't sure which model is right for you, don'

New NailaoLocker ransomware used against EU healthcare orgs

A previously undocumented ransomware payload named NailaoLocker has been spotted in attacks targeting European healthcare organizations between June and October 2024. The attacks exploited CVE-2024-24919, a Check Point Security Gateway vulnerability, to gain access to targeted networks and deploy the ShadowPad and PlugX malware, two families tightly associated with Chinese state-sponsored threat groups. Orange Cyberdefense CERT links the attacks to Chinese cyber-espionage tactics, though there
