 NFC sticker records GPS address to help car owners find bicycles

Recently, five students in the 20-year-old Groningen applied NFC chip technology to make stickers and a system for finding bicycles. In the Netherlands where a bicycle is in hand, this is a big news.
In the unlikely event that this seemingly simplistic sticker is applied, people will no longer have to worry about it in the middle of the night because it is too dark to find a bicycle. However, what I want to know most is that if I put it on the key or in the car, can I not find the key and the car in the future, and open the phone to know where they are?
Since Groningen is a well-known city in the Netherlands, the number of local students is large, and the favorite means of transportation for students is bicycles. But many people often encounter such troubles: after attending a party in the middle of the night or coming out of the bar, they can't find where the bicycle is parked.
How do you find a bicycle?
To solve this problem, five Groningen students combined the most popular IoT (Internet of Things) concept with the NFC chip technology that we have become commonplace in everyday life. So, there is a good idea to solve the problem that students can't find bicycles.
They made an NFC chip sticker and positioned it for the sticker through a mobile app they developed called "Wheel Reveal." After parking the bicycle, point the phone at the NFC chip sticker, the app will automatically open and store the sticker position, which is the positioning of the bicycle.
Conversely, when you are looking for a bike, open the app and click on the pre-stored location, Google Maps will automatically open to locate the bike location for you. For the accuracy of bicycle positioning, this app also has settings, NFC chip stickers can help you achieve the highest precision of 5 meters positioning, of course, if you choose this positioning accuracy, you probably need to wait 10 seconds to respond to the system.
Some words above don’t understand? Here is the lesson!
The first important term to be explained is the "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 10 cm at 13.56 MHz. Within the distance.
In fact, this technology is very common in our lives. For example, if you use the traffic card to sweep the card, you can swipe the door. The door of the building will be opened when you touch the door. The advanced one has a contact card credit card and so on.
The five students turned this online NFC chip sticker, which sold less than 50 yuan, into a positioning terminal for the Wheel Reveal system that they developed.
The other one is very popular. However, the concept that many people have not noticed is the Internet of Things (IoT). As an important part of Smart City, one of its distinguishing features is that "Everyone can apply electronics. Tags connect real objects to the Internet, and they can be found on the Internet of Things.
