Safety feature that you will hopefully never need: Emergency information that can be read directly from the helmet buckle using NFC

In collaboration with Twiceme Technology, Fidlock is building NFC chips into helmet buckles. This will give first responders access to medical information and emergency contacts directly via the helmet. The new buckle systems will be available to helmet manufacturers from the second half of the year. The first applications are planned for cycling and winter sports helmets.

Fidlock is working with the Swedish company Twiceme Technology to incorporate NFC-based security functions into chinstrap buckles. The technology utilises Near Field Communication, a short-range radio technology that is also used in contactless bank cards. The chip in the buckle does not require a battery and does not need to be charged.

Relevant information for first aiders

First responders can scan the buckle with a smartphone and gain access to stored emergency information. This includes medical data such as allergies or previous illnesses as well as contact details of relatives. The user stores this information in the Twiceme app in advance. The technology also works without the helmet having an active internet connection.

The Fidlock buckles equipped with NFC chips will be launched on the market in the second half of the year. Helmet manufacturers can integrate the systems into their products without having to fundamentally change the helmet design. The initial focus is on helmets for cycling and winter sports. Fidlock founder Joachim Fiedler sees the integration as an extension of mechanical fastening technology to include digital functions.

Assessment from the editorial team

You might think that emergency information via NFC is not necessary. After all, emergency information can also be set up on a smartphone, which can be called up even when the display is locked. But what happens in the event of an accident? Where can first responders find the smartphone? In the jersey pocket, in the frame pocket or in the cargo bike shorts? It might even be broken.

Holding your smartphone to the buckle of your chin strap to access the relevant emergency information seems like a sensible alternative. Provided you know that the information can be found there.
