The use of radio frequency technology has made it easier to tens of thousands of marathon runners, rather than spending a lot of manpower and material resources in the past. The motion timing system is based on TI-Rfid technology and will collect data from all marathon runners from around the world. ChampionChip’s timing system is to attach a TI-RFID sensor to the athlete’s shoes, when the athletes record through the ground or underground sensing antenna buried on the starting line and the finish line. This ensures that every athlete’s information can be recorded.

1)Accepted by many important events in the world
2)At the same time, it is also possible to track the time of individual athletes in the competition.
3)Place sensing antennas at some temporary inspection locations to prevent fraud
4)Can also be applied to triathlon, cycling and skating competitions
5)Game data can be placed on the Internet so that everyone can see it

In the 1999 marathon, Boston used TI-Rfid technology for timing management and placed entrant information on the Internet. The sensor is attached to each athlete’s shoelace by a plastic fixture so that each player’s game time can be easily recorded and sent to the Internet. Athletes’ friends and family can log in to the official website of the Boston Marathon, enter the athlete’s name or match number, and view the time of the athletes detected by the test stations set every 3 miles and update them at any time.




What is iButton?
The iButton is a computer chip packaged in a 16mm thick stainless steel housing. Thanks to its unique rugged casing, the latest information can be carried anywhere, along with people or objects.

What do I need to do to implement an iButton application?
Any iButton application consists of the following four basic parts. iButton
2. Host system: Can be a PC, laptop, PDA, or embedded system.
3. Read/write device, which can write information to the button or read information from the button. It can be the blue dot, pen detector or handheld device mentioned above.
4. Connect the iButton to the computer and generate the software layer of the required information in the desired format. Multiple software development tools (SDKs) are available for free download from the website. To get a list of SDKs and download links, see this page.

What advantages does iButton have over other technologies?
When developing an iButton solution, you might think of many complementary technologies. It may be barcodes, RFID tags, magnetic strips, proximity cards, and smart cards. Unlike barcodes and magnetic stripe cards, most iButtons can not only read but also write. In addition, iButton’s communication speed and product range far exceeds the simple memory that RFID typically uses. In terms of ruggedness, thin plastic smart cards are not as strong as the high-strength iButton.


At present, most hospitals in obstetrics and gynecology generally use the logo ring for mothers and babies when they are born, until they are discharged from the hospital to identify the mother and the baby. This symbol ring is a pure physical medium and can be easily exchanged. The existing management system of the hospital will not allow the families of the visiting infants to enter and limit the number of people, and control the idle personnel to enter and exit. Even so, it is difficult to do so in actual management because family members are eager to visit mothers and children. How to solve the problem of stolen baby and prevent mistakes is a technical problem that the maternity hospital urgently needs to solve.
Therefore, according to the actual situation of the hospital and management needs, the hospital mother-infant RFID wristband management system designed with advanced IoT technology is based on the principle of openness, supporting both centralized management and humanized services.
