Unusual iPhone Case Allows Images Display on the Back

In Japan, an unusual iPhone case has been invented that allows displaying images on the back of the case. The E-link panel is colored and almost does not drain the smartphone's battery - power is only required when updating the screensaver via NFC. In addition to the obvious opportunity to stand out, you can, for example, insert a QR code of your train ticket there and not worry about the smartphone running out of charge. Price - $79.
