Quick Start

Setting up the database, registering cards, receive an SMS, test scenarios, uploading data, confirm results.


This getting started guide takes under 30 minutes to complete.


To get started, ask two people to help you test the system. You will need three cards in total, one for you and two for your helpers. One card holder will move further away, the other card holder will stay near to you, at six feet or closer.  This will help confirm close contact.


Contact Harald has been designed specifically for contact tracing, the cards need to be worn with the supplied lanyards or clips and worn in front.  Because Bluetooth inside the cards performs differently when not on a person, for accuracy please test on people, not simply placed on a table or chair.

Getting started

Setting up Visitor-Log app to the secure database

To link your Visitor-Log app to the secure database, we need to add your customer ID along with your login credentials. Please refer to your Welcome Letter to retrieve login details.

Fast Scan & Battery Life

There is a trade off between fast scan and battery life. In the Visitor-log settings page, tap Card Configuration
To the right of the screen, ensure Fast Scan is disabled unless you specifically need fast scan mode

  1. For cards without an accelerometer, this feature does not take effect. Non-accelerometer cards cannot run in fast scan mode and will have a 6 month battery life.

  2. For cards with an accelerometer. Turning fast scan on will increase the probability of picking up contacts especially in noisy RF environments but will reduce the battery life from 9 months to 6 months.

Setting up the secure database

As the Super Admin, you have additional privileges to setup the system.

Open your browser such as Chrome or Safari.  You can perform this step on your laptop, desktop or other device.

1. Log in with your Super Admin details

2. Change your password

In the top right corner, click on the username.


Click on Change password. Update your password now.


For this quick start, we will not add other users to the system.

3. Customize the welcome SMS

Each time a new card is enrolled, a welcome SMS and/or Email is sent to the card holder. This can be a short consent message and your facility contact information.


Click on Communications then Saved Templates on the left hand side navigation menu. You can set up multiple templates for SMS and email communication from your organisation. 


Click on the Edit button next to the Welcome SMS in the list.

Edit the Message body and click Save. Do not change the ‘Welcome’ title.

Registering cards

The iPad is used to register cards. Personal data is securely transferred to the database and stored encrypted. 
No personal information is stored or saved to the card. 

A note on privacy

Each card is assigned a random ID, which can only be matched against other card IDs if the owner of the card hands it over. During normal operation the card does not communicate with the Internet, WiFi or mobile phones.  Pressing the button will permit the card to temporarily communicate with a secure App on the iPad or other device via Bluetooth. The stored random IDs are uploaded to the database for matching. 

  1. Open the iPad app

  2. Tap the Register Permanent button

  3. Answer facility screening questions
    Each card holder may be asked screening questions. The questions can be customized to your facility.  


  4. Tick the SMS consent box
    The cardholder must tick the SMS consent box to receive welcome and follow-up SMSs. We customized the SMS in an earlier step. Click Next.


  5. Register the card holder. Enter the card holder’s details with a valid phone number and email address. 

    Click Scan QR-code to register the card.  Hold the card in front of the camera, until the QR-code is automatically registered.  This works best with reasonable ambient light. Click Save Profile


  6. Register the card. To save the random ID to the card, press the button on the front of the card at the top.  You will see a blue LED (on the back of the card) flash. The App will display ‘updating the card’.  A confirmation message will then show ‘Profile created.’  

    Receive an SMS:


  7. An SMS will be sent to the card holder. 
    (If the SMS is not received, please wait a moment. Occasionally SMS can be delayed by the carrier. Also check that the phone number was entered correctly and the cardholder consented to receive SMSs).

    This is the first registered card.  Bluetooth on the card is now looking for other cards in close proximity. 

    Test Scenarios:

    This is the first registered card. Bluetooth on the card is now looking for other cards in close proximity. 

    Ask your helper to put the card around their neck and walk away, perhaps to the next room or greater than 20 feet away and wait for 20 minutes. This is the distant card holder.


  8. Tap Create another profile to register. Follow the steps above and register the second card holder and yourself.  Stay together within six feet of each other.

    Once finished, you should have three cards registered, one person further away and two close together, all wearing the Contact Harald cards.  Wait six minutes or more minutes then move to the next step.

How contact events are recorded

Contact Harald can record two types of contacts. A fleeting contact and a contact sustained for two minutes or more. 


When enabled, the card can record a contact as fleeting as soon as it detects another card in the specified fleeting contact range which is set when registering or uploading a card..


If a contact is sustained for 2 minutes or more in one of four ranges <1m, <2m, <4m and <8m(if enabled), the contact will be reported by minutes of contact.


Because Bluetooth 5.0 technology uses radio waves, the distance between two people is approximate, due to radio transmissions and other factors. The best performance is achieved when the Contact Harald card is worn in front, using the supplied lanyard or pocket clip. 


If for example the card is in your back pocket it will record events behind you, which defeats the purpose as a contact event is a record of an event from the front, from potential airborne particles.

Uploading data

  1. Now that six minutes or more has passed, we can test an upload.  Take your card from the person nearest to you.

  2. Open the iPad app

  3. Tap the Upload Card button. 

  4. Click the button on the front of the card at the top. You will see a blue LED (on the back of the card) flash.  The App will display ‘Transferring data’. 

  5. We now have proximity data loaded onto the secure server.

Confirm Results

  1. Go back to the secure Contact Harald website. You may need to log back in.

  2. Enter the Contact Harald secure website URL, username and password. This URL was supplied to you in the welcome email.  Log-on will be your email address and a temporary password.

  3. Once logged in, click on Contact Tracing, on the left hand side menu, or from the top menu (if you are on a mobile device).

  4. You can look up a person by name or email or phone number. For now, leave all fields blank and click the Contact Trace button. Leaving all fields blank will look up all people who have at least one contact event.

  5. You should see a match with your name and the person next to you, showing that 1 person has been in contact with the other. Click Contact Trace on the right side of the name. (See screenshot below)

  6. In the example (see screenshot below), we will be looking at who Jason Smith has been in contact with.

  7. Jason Smith has been in contact with Laura Reeves for a total of 10 minutes.  If you need a breakdown of the contact events and approximate time periods click on Period from the View menu.  For now, we will skip this and go to sending an SMS.

Reference 6. Jason Smith has been in contact with Laura Reeves (Click to zoom in)

8. Tick the box next to Laura, this will enable the Send SMS and Send Email buttons.

This enables you to quickly inform others if needed, such as visitors or staff previously in contact, that they may need to isolate and get tested.

In the example above, if Jason Smith was in contact with more than one person, this would be the list of contacts, which you could then tick or not tick.

9. Tap the send SMS or send email.  Compose your message or use a system stored template (templates can be customized by you). Click Send Now.

This completes the first sample run of the Contact Harald system.  You can now explore further functions of the system or review the documentation.  If you have any questions feel free to contact us at or call us.
