Twiceme Frequently Asked Questions

What is Twiceme® technology?

Twiceme® is an integrated NFC technology that allows you to store essential personal information directly in your helmet. In case of emergency, this information can help first responders quickly access key details when it matters most.

How does Twiceme® work?

Twiceme® uses an embedded NFC chip. By placing an NFC-enabled smartphone near the helmet, relevant information may be accessed, depending on device compatibility and proper setup.

Do I need to create an account?

Yes. To use Twiceme®, you need to create an account and set up your personal information through the Twiceme® app. Keeping your information accurate and up to date is essential for the system to work effectively.

Is Twiceme® always guaranteed to work?

Twiceme® is designed to support access to important information, but its functionality depends on factors such as device compatibility, connectivity, and correct setup. For this reason, availability of information cannot be guaranteed in every situation.

Does Twiceme® replace emergency systems?

No. Twiceme® is a support tool intended to assist in emergency situations. It does not replace emergency services, medical care, or professional judgment.
