There have been several instances of E Ink displays finding innovative applications. That includes automobiles (both in the dashboard or the entire car exterior), to something as radical as guitars and smart toilets. In comparison, a keychain with an integrated E Ink display might seem a lot more conventional, the sort of thing that you’d wonder how you ever lived without so far.
The keychain comes with a 1.54-inch monochrome E Ink display, which offers a 27 mm x 27 mm display area with having 200 x 200 pixels resolution. The display offers a wide 170-degree viewing angle, something that is typical of E Ink displays. Another key feature of E Ink displays is their excellent readability, even when viewed under direct sunlight.
The E Ink screen can be used to display some information or images. There is no battery needed, and the power required for its operation is derived entirely via NFC. This makes its operation very hassle-free as there is no complicated wiring involved, nor is there the need for recharging the same at regular intervals.
Updating content is also very simple and can be done just by tapping on the display. Both energy transfer and data update take place using NFC technology. All of it is encased within a white case with sides made of a rounded metal frame. This gives it a premium yet sturdy feel. There is a hole made at one of the corners, which serves as the hanging hole. You can also attach a detachable strap to the hole if you so want.
The entire keychain unit weighs 1.76 ounces and sports dimensions of 1.63 x 1.59 x 0.28 inches. Among the use cases the company envisages for the E Ink-enabled keychain are applications such as business card, QR code tag, event pass or lanyard, smart pet tag, luggage tag, and store link, to name a few.
The keychain can be ordered via the retail site Excelia where it is listed for $7.99 apiece. That is after a 60 percent price adjustment with the original price listed as $19.99. So, that should be a good reason to place your order for the innovative futuristic keychain that is as sleek as is versatile and functional.
