Square unveils thinner, more accurate card reader for mobile devices

Add as a preferred source on Google

The original Square Reader – a compact, easy-to-use, and affordable point of sale system for mobile devices – was a massive hit when it was first released. Despite the warm reception, engineers and designers at Square felt they improve it. For the past couple years, they’ve been working to improve Reader. Earlier today, the company pulled the curtain on a new version that boasts a sleeker design and a completely overhauled electronic interior.

In the first generation Reader, Square used the same magnetic read head (the part that grabs information from a card’s magnetic strip) that you could find in a tape deck from the 1980s. The new read head, however, is much more accurate, and uses a spring system to better grip the card. In addition to reducing scan errors, this also enabled desginers to make the device 45 percent thinner than the first iteration.

The new and improved scanning hardware isn’t the only component Square has overhauled. Engineers also built a custom chip for the device that handles all of Square’s data interpretation, encryption, and transfer functions. The old version used a number of different components to accomplish all these tasks. As a result, the new Reader will work with a greater number of devices without issues and get more valid card readings on the first swipe.

This custom-built chip also makes the card reader much more energy efficient. By drastically reducing the reader’s power consumption, Square was able to ditch the device’s internal battery and now draws all the juice it needs from your device’s headphone jack.

The new Reader is available on Square’s website today, and will make its way into stores starting next year.

Elon Musk has revealed ambitious plans for Neuralink, and they go beyond controlling computers with your thoughts. The company is developing two brain implants, Telepathy and Blindsight, aimed at helping people with paralysis and severe vision loss. Musk also believes future advances could help people regain control of their hands and legs by reconnecting the brain with their limbs.

Sony has shrunk its glasses-free 3D technology into a tiny screen, and it can bring anime characters to life on your desk
It's almost like having a digital, three-dimensional companion on your desk.
Sony's smaller 3D display for desk

Glasses-free 3D has always felt like a luxury I could admire from afar. Those screens were built for design studios, not smaller desks like mine. But Sony’s new version is small enough to sit beside my keyboard, and I’m genuinely excited.

The company has unveiled the ELF-MN1, a 6-inch display that makes 3D characters and avatars look like they’re coming out of the screen without any special glasses or a headset. It plugs into a phone or PC with one USB-C cable, and that’s pretty much it (via Sony).

3D-printed ghost guns are a notorious blind spot. Scientists may have finally cracked the traceability problem
The plastic used to make these weapons could hold clues that conventional forensic methods often miss.

Most conventional firearms come with serial numbers and leave unique microscopic markings on bullets and cartridge cases when fired. Investigators can use these clues to trace weapons or connect them to crimes. However, 3D-printed firearms, commonly called ghost guns, present a different challenge. They can be manufactured without serial numbers, and their unconventional construction can make traditional forensic analysis more difficult.

Now, researchers in Australia may have found another way to trace these weapons, using clues hidden in the plastic they're made from.
