1. RFID Automatic Bicycle Lock Students: 張納堂, 曾奕智, 許祐群

2. What is the Problem? Time Wasting: -The Average NTU students spends 7.3 hours a year locking/unlocking their bicycle according to our small experiment Annoying -Let’s face it, it is annoying to lock and unlock your bicycle many times a day for a whole year not to mention it will get you dirty countless times.

3. Our Experiment We polled 15 random NTU students on campus and found out that: They lock/unlock their bicycles 12 times per school day on average. By experimentation we found out that we: Spend average of 9.74 s locking Spend average of 7.22 s unlocking Results: Considering those times and using them for 5 days a week for a whole year then the average NTU student spends 7.3 hours a year locking and unlocking their bicycle!

4. What is our Solution? RFID (Radio Frequency Identification) We can automate the locking and unlocking process of a bicycle using RFID which is basically communication between a tag and a reader. Reader (interrogator)Tag (label)

5. How do we Plan to Make this Work? Materials The materials we will use to implement our idea are: a programmable/writable RFID tag, RFID Card Copier/Duplicator, RFID reader and a mountable lock for bicycles which closes automatically depending on the detection status of the reader. Implementation Fixed RFID reader RFID Reader connected to lock Supplying power to the RFID reader and lock
