This Smart Wallet Has a Built-In Tracking Device for Added Security

Keeping all of your necessities—cash, identification, membership, and credit cards—in your back pocket or purse can sometimes feel like a gamble. Now, a Kickstarter campaign for the Ekster Wallet may solve your wallet woes: Not only does it provides a cool place to store the things you need, but it also features a tracking system to help you find them in case they go missing.

The smart wallet connects to your smartphone and sends an alert when your wallet and phone are out of range from one another. If you drop the wallet on the street, or leave it at the bar, simply use the tracking system to figure out where you left it. There's also an option to call your wallet and have it give off an audible ring, which makes it easier for you (or someone nearby) to find it. 

Other features of the Ekster Wallet (as outlined in the video above) include a spring-loaded mechanism that makes reaching your credit cards easier, RFID/NFC blocking technology that stops thieves from electronically skimming your information, and a strap where you can keep cash and cards for quick access.

With several days left in the Kickstarter campaign, the Ekster Wallet has already exceeded its $16,440 goal and is nearing the $110,000 mark. For those who want a smart wallet of their own, pledges can still be made in exchange for early bird specials.

5 Scrapped Designs for the World's Most Famous Buildings

When an architect gets commissioned to build a skyscraper or a memorial, they’re usually not the only applicant for the job. Other teams of designers submit their own ideas for how it should look, too, but these are eventually passed over in favor of the final design. This is the case for some of the world’s most recognizable landmarks—in an alternate world, the Arc de Triomphe might have been a three-story-tall elephant statue, and the Lincoln Memorial a step pyramid.

GoCompare, a comparison site for financial services, dug into these could-have-been designs for Alternate Architecture, an illustrated collection of scrapped designs for some of the most famous structures in the world, from Chicago's Tribune Tower to the Sydney Opera House.

This 1907 Vision Test Was Designed for People of All Nationalities

At the turn of the 20th century, San Francisco was a diverse place. In fact, Angel Island Immigration Station, located on an island in the San Francisco Bay, was known as the “Ellis Island of the West,” processing some 300,000 people coming to the U.S. in the early 1900s. George Mayerle, a German optometrist working in the city at the time, encountered this diversity of languages and cultures every day in his practice. So in the 1890s, Mayerle created what was billed as “the only [eye] chart published that can be used by people of any nationality,” as The Public Domain Review alerts us.

Anticipating the difficulty immigrants, like those from China or Russia, would face when trying to read a vision test made solely with Roman letters for English-speaking readers, he designed a test that included multiple scripts. For his patients that were illiterate, he included symbols. It features two different styles of Roman scripts for English-speaking and European readers, and characters in Cyrillic, Hebrew, Japanese, and Chinese scripts as well as drawings of dogs, cats, and eyes designed to test the vision of children and others who couldn't read.

The chart, published in 1907 and measuring 22 inches by 28 inches, was double-sided, featuring black text on a white background on one side and white text on a black background on the other. According to Stephen P. Rice, an American studies professor at Ramapo College of New Jersey, there are other facets of the chart designed to test for a wide range of vision issues, including astigmatism and color vision.

As he explains in the 2012 history of the National Library of Medicine’s collections, Hidden Treasure [PDF], the worldly angle was partly a marketing strategy on Mayerle’s part. (He told fellow optometrists that the design “makes a good impression and convinces the patient of your professional expertness.”)

But that doesn’t make it a less valuable historical object. As Rice writes, “the ‘international’ chart is an artifact of an immigrant nation—produced by a German optician in a polyglot city where West met East (and which was then undergoing massive rebuilding after the 1906 earthquake)—and of a globalizing economy.”

These days, you probably won’t find a doctor who still uses Mayerle’s chart. But some century-old vision tests are still in use today. Shinobu Ishihara’s design for a visual test for colorblindness—those familiar circles filled with colored dots that form numbers in the center—were first sold internationally in 1917, and they remain the most popular way to identify deficiencies in color vision.
