NFC Sticker Records GPS Address To Help Car Owners Find The Bike
In case one day this simple-looking sticker is applied, people will no longer have to worry about finding a bicycle in the middle of the night because it is too dark. However, what I want to know most is, if I put it on the key or the car, will I find the key and the car later, and open the phone to know where they are?
Since Groningen is a well-known city in the Netherlands, with a large number of local students, the students’ favorite means of transportation is bicycles. But many people often encounter the trouble: After attending a party in the middle of the night or walking out of a bar, they can't find where their bicycles are parked for a while.
How do stickers find bicycles?
To solve this problem, five Groningen students combined the most popular concept of IoT (Internet of Things) and the NFC chip technology that we have become familiar with in daily life. So, there is this good idea to solve the problem of students not finding bicycles.
They made a sticker with an NFC chip and used a mobile app they developed called "Wheel Reveal" to locate the sticker. After parking the bicycle, point the phone at this NFC chip sticker, the APP will automatically open and store the position of the sticker, which is the location of the bicycle.
Conversely, when you are looking for a bicycle, open the APP, click on the pre-stored location, and Google Maps will automatically open to locate the location of the bike for you. For the accuracy of bicycle positioning, this APP also has settings. The NFC chip sticker can help you complete the positioning with the highest accuracy of 5 meters. Of course, if you choose this positioning accuracy, you probably need to wait 10 seconds for the system to respond.
The first important term to explain is "NFC chip". The full name of NFC is Near Field Communication, which is near field communication. It is a short-range high-frequency radio technology that runs at a frequency of 13.56MHz at 10 cm. Within the distance.
In fact, this technology is very common in our lives. For example, the transportation card can be swiped with one swipe, the entrance guard of the building opens when the door is touched, and the more advanced ones include contact-swiping credit cards. The five students transformed the NFC chip sticker sold online for less than 50 yuan and turned it into the positioning terminal of the Wheel Reveal system developed by themselves. Another popular concept that many people have not noticed is the "IoT" (Internet of Things). As an important part of the Smart City (Smart City), one of its distinctive features is that "everyone can use electronic Tags connect real objects online, and their specific locations can be found on the Internet of Things.
