If you’re like us, it’s been ages since the last time you printed out a concert ticket and had to have it stamped. But in some regions (and theme parks) of the world, the ink-drenched rubber stamping contraptions serve as the only means of validation. If the folks at Echoss have their way, though, you might start seeing a lot more around — but not how you might remember them.

At Mobile World Congress in Barcelona, the Japan-based Echoss showed the Echoss Smart Stamp, a stamp that’s compatible with smartphones. Just like an off-the-shelf stamp at your local Staples, it doesn’t pack a battery, processors, or any electronics that require power, works offline, and springs back slightly when pressed against a surface.

But unlike conventional stamps, the Smart Stamp validates tickets and coupons with “capacitive point technology.” Each unit packs a pattern of stylus-like points concealed beneath a conductive sheet, and when the stylus-like points make contact with a touchscreen and Smart Stamp-compatible app, the phone registers with Echos’ certification center. After a second or so, the ticket holder is good to go.

We asked Echoss about the potential for fraud — it doesn’t seem out of the realm of possibility that a determined hacker could disassemble a Smart Stamp and produce copies of the geometric pattern. But a company rep told Digital Trends that once a virtual ticket has been stamped, Echoss records the location and time, and each stamp’s pattern actuates at very specific angles on the smartphone screen. Simply put, if someone were to take one apart, they wouldn’t necessarily be able to produce a duplicate.

The standard Smart Stamp comes in blue and white, but a customized version, the Paper Stamp, lets brands create designs of their own. Echoss envision performers distributing collectible stamps for buzzy promotions, and sweepstakes holders awarding Paper Stamps as prizes. “[They] can create a unique fandom culture,” Echoss said.

That’s less of a stretch than you might think. Smart Stamps are apparently quite popular overseas — Echoss’s partners include Samsung, NEC, Huawei, and WeChat. One of the most popular apps, Echossbook, lets users collect stamps in exchange for a coupon. Another, Cevly, rewards hair studio customers for rebooking stylists.

And it might not be long before they make their way to the U.S. — Echoss plans to announce new partners in the coming weeks.

So don’t freak out if the barista at your next coffee stop stamps — not scans — your digital loyalty card.

This tiny sensor is about to change your phone camera forever
Spectricity's S1 Spectral Image Sensor.

“We believe there's a real opportunity to develop and use a spectral imager in a smartphone. Despite all the progress which has been made with different cameras and the computing power of a smartphone, none can really identify the true color of a picture.”

This is how Spectricity CEO Vincent Mouret described the company’s mission to Digital Trends in a recent interview, as well as the reason why it's making a miniaturized spectral image sensor that’s ready for use in a smartphone. But what exactly is a spectral sensor, and how does it work? It turns out, it can do a whole lot more than just capture pretty colors.

CES 2023: The Lenovo Smart Paper looks like a great Kindle Scribe killer
Menu options on the Lenovo Smart Paper.

At CES 2023 this week, Lenovo announced the new Smart Paper tablet. As the name implies, it's an e-paper tablet that's built to replace your notebook and pen and "smarten" them up. It goes on sale later this year.

All e-ink devices aim to replicate the feel of pulpy paper and polished penmanship as well as they can, and the Lenovo Smart Paper is no exception. Coming with a 10.3-inch display, the Smart Paper is built very much like a notebook. There's an anti-glare touch display, and it comes in at a very wide aspect ratio that's different from typical tablets -- and all of it is housed in a sleek metal chassis.

The future of blood oxygen monitoring lies with your phone’s camera
Measuring SpO2 with smartphone camera and flash

Smartphones are already capable of some neat health-centric tricks. From step counting and sleep tracking to measuring pulse and respiration rate, the phone in your pocket is quite a powerful-health monitoring machine. Now, a team of scientists from the University of Washington is looking to add blood oxygen level measurement to that bag of tricks.

In a paper published inNJP Digital Medicine, the team details what it calls the “first clinical development validation on a smartphone camera-based SpO2 sensing system.” To put it simply, the team developed an algorithm and proved that smartphones could measure the blood oxygen saturation level to the same baseline level as approved by the Food and Drug Administration (FDA) for over-the-counter pulse oximeters.
