"Unhackable" RFID chip to keep your credit cards safe

Radio frequency identification (RFID) chips have made cashless payments commonplace and opened the way to automatic inventory control. However, they've also made it possible for credit card details and other private information to be stolen wirelessly. To make things a bit more secure, MIT and Texas Instruments are developing an "unhackable" RFID chip that's designed to fend off information-stealing attacks.

World's smallest optical switch uses a single atom

The rapid and on-going development of micro-miniature optical electronic devices is helping to usher in a new era of photonic computers and light-based memories that promise super-fast processor speeds and ultra-secure communications. However, as these components are shrunk ever further, fundamental limits to their dimensions are dictated by the wavelength of light itself. Now researchers at ETH Zurich claim to have overcome this limitation by creating both the world's smallest optical switch using a single atom, and accompanying circuitry that appears to break the rules by being smaller than the wavelength of the light that passes through it.

NASA's new laser-based modem could revolutionize data-crunching

For years now, fiber optics has been synonymous with super-speed communications and data transfer, but now NASA is working to develop the next generation of high-speed modems using an emerging technology called integrated photonics. The agency's first integrated photonics modem is set to be deployed aboard the International Space Station in 2020. The palm-sized device makes use of optics-based functions like lasers, switches and wires that are all integrated on a microchip much like those in our cell phones.

Cassia Hub extends Bluetooth range to 1,000 feet

While Bluetooth has become a popular way to connect devices within very close proximity (30 ft/9 m or less), its range limitations and inability to connect more than one device to another have limited its use. A new Bluetooth-enabled hub introduced by Cassia at CES could change that by extending the range to 1,000 feet (304 m) or through three interior walls, and allowing up to 22 different devices to be connected at once.

myFC readies for launch of world's smallest fuel cell charger

If you need to power up your smartphone but are nowhere near an AC outlet … well, that's why Sweden's SiGNa Chemistry and myFC developed the PowerTrekk fuel cell/battery. While it's a handy device for off-grid device-charging, it's not exactly the type of thing that you'd just slip into a purse or pocket. myFC's new JAQ, however, is exactly that. It's being billed as the world's smallest fuel cell charger.
