Frequently asked questions

Find answers to frequently asked questions about Twiceme's technology, usage, privacy, and troubleshooting.


Can I access the medical ID on Twiceme without the app?

Yes, profiles uploaded using the Twiceme app version 5.0 or later can be accessed without the app by utilizing the background scan feature on an NFC-enabled smartphone.

To provide a seamless user experience when accessing information without the Twiceme app, the smartphone displays the accessed information on the website. It’s important to note that none of the presented information is uploaded to the web. Only the HTML code is downloaded from the web purely for presentation purposes.

If you have any further inquiries about this process, please feel free to contact us. We will be more than happy to provide a more detailed explanation.

For iPhones with the app: No
For iPhones without the app: Yes
For Androids with the app: No
For Androids without the app: Yes

If I have an iPhone 7,8, or X, how to use the NFC background scan functionality?

Since Apple didn’t prepare those models with an NFC background scan functionality, you need to open the control center and tap the “NFC Tag Reader” button to activate the background scan functionality.

Is it possible to delete a profile on my Twiceme equipped gear?

Yes, by using the Twiceme app.

Can I change the information uploaded to my Twiceme equipped gear?

Yes, by using the Twiceme app.

Can I store several profiles in the Twiceme app?

Yes. You are then able to quickly change which profile you want to upload on the equipment so that it matches the person who uses it.

How can I upload or delete a profile to my equipment using the Twiceme app?

Once you have created a profile of safety information, you need to add a piece of equipment to that profile. Once you’ve done that, you can find the upload and delete info buttons on the equipment page.

Interaction with a Twiceme equipment

How does a smartphone interact with the Twiceme enhanced equipment?

Tap your scanning area/NFC antenna of your phone directly on top of the Twiceme symbol. If it doesn’t work immediately, slowly hover the smartphone around the symbol.

What do I need to access the medical ID on Twiceme?

You need an NFC enabled smartphone.

Do I need any mobile network or internet connection to access the medical ID uploaded to Twiceme enhanced equipment?

When using the Twiceme app, you can access the medical ID uploaded to the equipment without having any mobile network or internet connection.

How long is the reading distance between the integrated Twiceme device on your equipment and the smartphone?

~10 mm. Though it depends on the phone model and strength of the NFC reader functionality.

Do I need to charge my Twiceme gear?

No, the device does not contain any batteries so no charging is needed.

Is the NFC chip used in helmets an active or passive tag? Does it emit radiation?

Passive NFC (Near Field Communication) tags do not emit radiation on their own. They are passive devices that rely on inductive coupling to transmit data to an NFC reader or device. Here’s how it works:

  1. Passive NFC tags contain a coil of wire and a small integrated circuit (IC) that stores information.
  2. When an NFC reader or device comes into close proximity (typically within a few centimeters or inches) to the NFC tag, it generates an electromagnetic field.
  3. This electromagnetic field induces a current in the coil of the NFC tag. The energy from the reader’s field powers the NFC tag’s IC.
  4. The powered NFC tag then modulates the induced current to send data back to the reader.

So, in this process, the NFC tag does not emit radiation on its own. It only responds when in the presence of an NFC reader’s electromagnetic field. This is why NFC is considered a short-range communication technology, and the range of communication is limited to very close proximity.
It’s important to note that the NFC reader or device generates the electromagnetic field, and this field is what allows the NFC communication to occur. The NFC tag itself does not emit any radiation unless it is actively being read by a compatible NFC reader.

Information & Data privacy

Who has decided what information that can be uploaded on Twiceme?

The safety information that a user can upload on Twiceme has carefully been evaluated in consultation with ambulance and rescue professionals.

Does Twiceme collect personal data of their users?

The Company will monitor your use in an anonymous way, by using a method that will not identify you as a person, in order to make the Application more user friendly. The Company does not and cannot, in any other way, monitor your access, save, record, transfer or in any other way process the data you process in your hand-held mobile device using the Application or the NFC hardware, including but not limited to personal data as defined in the EU Regulation 2016/679 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data.

App troubleshooting

Update your smartphone and the app
Easiest solution to most problems with the app will always be:
• to update the operative system on your smartphone
• to update the app to the latest version in App Store or Google Play
Nothings happens when I scan

In order to use Twiceme, you need to place the NFC antenna on your smartphone directly on top of the Twiceme symbol on the equipment within 10 mm. Also, please take into consideration:

  • The placement of NFC antennas may differ from different smartphone brands and models
  • Avoid thick cases on your smartphone
No menu button on iPhone

Your operative system on your iPhone is too old, hence all NFC functionalities hasn’t been updated. Please update to at least iOS 13 and update the twICEme app.

"NFC hardware not found" message

If you get the warning NFC hardware not found, the NFC functionality on your smartphone is switched off. If you have e.g. an updated Android smartphone, you can turn it on by going to: SettingsConnected Devices → Connection Preferences → NFC.
