Not everything in life can be predicted. Unexpected situations and medical emergencies can occur at any time. This makes it all the more important to get help quickly in such moments. Whether it’s a fall off a scooter, a loss of consciousness while exercising, or pain—every minute counts in an emergency. SOS-Check offers a technical solution for this. The system provides quick access to emergency contacts, medical advice, and important information—especially when those affected are unable to communicate on their own.

Story behind SOS-Check

It all started with a phone call: How can NFC be used to quickly provide the right information in an emergency - without stress and without wasting time?

The association Herzkrankes Kind Aachen e.V. (Heart Disease Children Aachen) found the perfect partner in NFC21. Discussions turned into workshops, ideas turned into solutions - and finally, SOS-Check was created: the online portal that, together with smart NFC products such as bracelets or pendants, becomes a reliable everyday companion.

Developed with passion, technology, and the shared goal of supporting people in exceptional situations.

SOS-Check
Smart Emergency Set

The SOS-Check Bundle was developed in close cooperation with the Herzkrankes Kind Aachen e.V. association and tested in practice.

With every bundle sold, we support the association's work with a donation of €5. At the same time, the proceeds go toward the further development of SOS-Check.

How it works

The SOS Check can be set up and filled out in just a few steps

Activate and fill in details
Scan and help
Update information
Step 1

Activate and fill in details

After the activation process, the profile can be filled with data. This includes:

  • Name and age
  • Emergency contacts
  • Diagnoses
  • Medication
  • Further notes
Step 2

Scan and help

Whether playing at the playground, on a school trip or in everyday life: parents can't always be there. And children can't always tell you what's going on in an emergency.

If necessary, the SOS Check can be scanned. We have built the system so that it also works under stress: The most important data is at the top, easy to read and understand.

Step 3

Update information

Data changes, the profile picture needs to be updated or a telephone number has been altered? All information entered can be easily adjusted and will be visible after the next scan.

Questions and answers

SOS-Check works with sensitive data, which is why transparency is particularly important to us.

All questions are answered openly and clearly here, so that it remains easy to understand how SOS-Check combines security, data protection, and responsibility.

No, there are no subscription fees or follow-up costs with SOS-Check. The NFC products are designed to last a long time.

Instead, new editions of bracelets, pendants, and cards will be offered regularly in case you get tired of the existing colors and designs.

The prices of SOS-Check products are calculated fairly to ensure both the further development and continued operation of the platform. We also want to use the included donation portion to support the valuable work of the association.

As part of the NFC-Smart family from NFC21, operating costs can be distributed across multiple platforms, which further supports the sustainable development of SOS-Check.

No, you don't need an app. All you need is an NFC-enabled smartphone: Simply hold your smartphone up to the SOS Check product and the profile will open directly in your browser – no installation required, easy to use and ready to go.

Yes. Since NFC chips offer only very limited storage space, an online profile is used to store all important information that can really help in an emergency.

The profile is optimized to load quickly and display reliably and without barriers on all smartphones.

SOS Check works best when users and clubs inform their community about the feature. Every helping hand and voice contributes to its success.

We are happy to provide information material for this purpose and welcome every opportunity to present and introduce SOS-Check.

No. All data remains within the platform and can be edited or deleted at any time.

SOS Check products are deliberately designed and priced so that the data does not have to be used as a source of income. This is in line with NFC21 GmbH's data protection promise.

SOS-Check is backed by NFC21 GmbH, based in Mülheim an der Ruhr. Our goal is to simplify access to important information and combine offline and online solutions.

Thanks to our collaboration with the association Herzkrankes Kind Aachen e.V. (Heart Disease Children Aachen), SOS-Check allows us to combine an accessible and worthy cause.
