BlackBoard - U

Always keeping in mind the ergonomics and portability, measures have been tried to keep as low as possible, resulting in a concept of just 73x57x28mm (without accessories) Making the reader comfortable and easy to handle. The LEDs are arranged in a U´shape, transmitting light through the translucent part and being reflected in the gap. All LEDs are tricolor, thus the device will be completely and perfectly enlightened. Four colors [Blue, Red, Green and Amber (green + red)] for user-product interactions are used. Workflow and feedbacks: ON / OFF After placing the switch in the ON position, the device flashes a intense blue, then stay in a soft blue tone (mixing blue with green LED) BLUETOOTH The chosen color is blue, and the leds will pulse when connecting and illuminate when paired. TRANSACTION The operation for all interactions will be the same: When a transaction is accepted the LEDs will change to green, when the transaction is denied the red LEDs will start flashing. BATTERY STATUS USB connected Green Leds progressively start flashing : Battery fully charged USB disconnected Amber Leds progressively start flashing: Battery needs to be charged (25% or less) Battery very low (10%): red continuous blinking within Interactions related to the battery will be made ​​during periods of inactivity to not confuse users. Because the magnetic stripe reader is not always needed and appears as an optional component, it was decided to incorporate as a separate element. Being the end user who decides to take it or not, all the time trying not to break with the aesthetics of the product. Trying not to an expensive product, and avoiding the use of an external support, the reader incorporates (at the bottom) holes that allow anchoring to the wall.
