Blackboard Reader Device Challenge entry 2

Hereby my second design for the Reader Device Challenge. This design has some similarity to my previous design, however this design is easierer to produce. The moulds needed for the plastic parts are simpler. Also this model has only one led instead of 8! The reader has a size of 100 x 65 x 22 mm, that makes this device easy portable. The small hook on top makes it possible to attach a keycord, put it around your neck and take it anywhere. On the front there is a white circle that is used for communication. Because this part can light up it is easy to see if the transaction is succeeded or denied. Also this part is used as on/off button. Placing the reader in its dock automatically connects the USB connector on the bottom to a charger/data cable. The dock can also be us as a wall mount with the slots in the back. To give the dock more stability a metal cilinder is added for more weight. Device workflow: On/off: To turn the device on or off simply hold the on/off button on the front. When the device turns on a white led start to glow. Bluetooth pairing: When not connected to an other Bluetooth device, the white led starts flashing. When a connection is made the white leds start to glow normally again. Sleep mode: To put the device into sleep mode shortly press the on/off button. The white led will light up at a set interval to show the device is in sleep mode. To wake it up simply press the on/off button again. Transaction: Transactions can be made by holding your card at the RFID reader on front or by using the mag reader at the right side. When a transaction is accepted the led changes to green, when the transaction is denied the led turns red. Battery: When the batteries starting to run low and they need to be replaced or the device needs to be connected to the dock for charging, a red led start flashing. Please, feel free to take a look at the 3D models.
