EyeNote® is a free mobile device application developed by BEP as an aid for blind or visually impaired individuals to identify U.S. Federal Reserve currency denominations from Series 1996 to the present. The app uses image recognition technology and the device’s integrated camera to recognize a note and communicate its denomination back to the user, via voice or unique auditable beeps or vibration patterns for privacy. * Utilizes VoiceOver for vocal and gesture feedback, if it is turned on. * Does not require a data connection to work. * One touch, hand-held operation. * Identifies note face and back in any orientation, including portions of the note. * Continuous scanning once application is open; taking a photo with the camera is not required. * Quick response time. * Supports English and Spanish languages. * Compatible with Apple mobile devices iOS11 or greater. EyeNote does not authenticate U.S. Federal Reserve notes as being either genuine or counterfeit. Please refer to the Apple AppStore℠ license agreement for additional information.

NaviLens is a high-density artificial markers system for long distance reading. The tags generated by this system are designed in order to be read from a long distance, without the need of focussing and even in motion. This makes them useful for blind and partly sighted people. All you need to do is to point the camera of the device to a tag in order to quickly read its contents. The application has a new sound system with which a blind person can locate the label in the space with precision, without the need for headphones. Notice: While we are installing this signage system in different locations, you can download sample labels in the same application. We have spent 5 years to create this new technology. We will be happy to receive your impressions and comments about the system. For more information please read at the quick help, included in the application. The NaviLens team
