Blackboard Reader Device Challenge entry 2

Introducing my second design for the Reader Device Challenge! This model is more production-friendly than its predecessor; it requires simpler moulds for plastic parts. It features one LED instead of eight and measures 100 x 65 x 22 mm, making it easy to carry around with a small hook for attaching a key cord. A white circle on the front functions as both a communication interface and an ON/OFF button. When placed in its dock, the device connects to a charger/data cable through the USB connector at the bottom. The dock can also be wall-mounted using the slots in the back, with added stability from a metal cylinder. Turning the device on or off is done by holding the front button, while Bluetooth pairing is indicated by flashing white LEDs. To enter sleep mode, briefly press the ON/OFF button; the LED will glow intermittently. To wake it up, simply press the button again. Transactions are processed through an RFID reader on the front or a magnetic reader on the side. A green LED signifies acceptance, while a red one denotes denial. If batteries run low, a flashing red LED indicates the need for replacement or charging via the dock. Don't forget to check out the 3D models!
