SOS-Check
Your SOS products with NFC for more safety
We develop innovative and smart SOS products suitable for people of all ages—whether children, teenagers, adults, or seniors. Our solutions make it possible to access important information quickly and easily via a smartphone. To do this, we integrate modern NFC technology: simply scan with your smartphone, and all relevant data is immediately visible—no app or login required.
How SOS-Check can help
SOS-Check offers quick and easy assistance in a variety of everyday situations.
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.

Always within reach, always with you, weather-resistant, and emergency information quickly available.

The SOS wristbands are reliable companions in everyday life – whether on the way to school, while playing, at work, or during sports. They are also safe to wear while swimming. They are available in three different sizes, and all important information can be accessed quickly: simply scan with a smartphone.
SOS cards
The SOS card is a digital emergency pass that allows all important information to be accessed easily via NFC scan or QR code scan. The card can be placed in a jacket pocket or the front pocket of a backpack, making it easy to access for anyone in any situation.
SOS tags
The SOS tag is an NFC- and QR-based emergency tag that can be attached to a backpack, school bag, travel luggage, or sports bag, for example. Simply scan via NFC or QR code and quickly access all information.
SOS sticker
The SOS sticker is an NFC- and QR-based sticker that can be attached to a desk in the office, a backpack, a phone case, a lunch box, or a water bottle, for example. Simply scan via NFC or QR code and quickly access all information.
SOS bundles
The SOS bundle consists of a wristband, tag, and emergency card and can be used flexibly in everyday life – on the wrist, on a backpack, or in a jacket pocket. This ensures that emergency information is easy to reach in different situations and can be read quickly with a smartphone. All products are robust and protected against external influences.

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.

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.
