At Nubart we care about the environment! You can choose the ecological material on which you want to print your cards:
High-strength special FSC-certified cardboard (recommended).
Recycled PVC.
Whatever material you choose, at Nubart we fully compensate for the CO2 emitted during the production of your order, including the transport of raw materials, the entire printing process, packaging and shipping to the destination. Click here to see the CO2 that we have offset so far.
All the "background work" of our technology takes place on the guide's smartphone. It is therefore desirable that your guides have a modern smartphone with a good processor and a reasonably new battery.
However, this does not affect the group members: for them the battery load is not much higher than when listening to a podcast or an audio book. For example, one hour of continuous use consumes 8% of the battery on a 4 year old Android phone.
About 20 MB per hour. Since our system is unidirectional (only the guide speaks) and we do not broadcast video, our system uses much less data than a video call in Zoom or Skype. Even less than a regular phone call!
Design customization is included in our Medium and Professional packages.
You send us the images, logos and other elements you want on your card and our designer will create several design proposals for you to choose from.
If you like the Nubart-branded design below, printed on eco-friendly extra strong cardboard, our minimum order for Nubart Live is our Basic Package with 500 units.
If you prefer to have your cards individually designed, the minimum order is 3,000.
If you buy our Nubart-branded cards, you can have two guides per each order of 500 cards (Basic Package).
So the more cards you order, the more guides can access our system. If you buy our Professional Package with 5.000 cards, the number of guides is unlimited.
No. You will only need one card per group member, as our Nubart Live cards are non-transferable, but reusable. Simply ask each member of your group to keep their own card for reuse during the trip.
To avoid confusion during the trip, we recommend that each user write his or her name on the card.
A small delay of up to one second between sender and receiver (latency) is unavoidable.
Latency is affected by several factors, including the performance of the smartphone, the quality of the connection, and whether the sender and receiver use the same mobile data provider.
However, if the guide is speaking in a low voice, the echo effect of latency will be barely noticeable, as the voice received on the smartphone will predominate for the visitor.
Back of a Nubart card Technically, we could generate unique QRs and make them scannable from a smartphone, like a digital boarding pass. But there are several good reasons to use our cards:
Not everyone knows how to scan a QR code. Our card offers an alternative option by entering an alphanumeric code.
There is always someone who arrives late to the group: Since our card is self-explanatory, all the guide has to do is to scan a card and silently hand it out to the newcomer, with almost no fuss.
Participants can always re-enter or re-scan the code on their card if there are problems with the smartphone (e.g. accidentally closing the browser).
The cards are not transferable, but a participant can reuse their own card for multiple tours.
If you want to take the call, just click "mute" and pick up the phone.
The group will remain on hold while you talk on the phone. When you are finished with the call, return to the browser. If you do not see everyone in the group with a green light, reload the page: the connections will be restored without having to scan all the QR codes again.
Note: If you are using an Android and you forget to click "mute" before accepting the call, visitors may be able to hear what you are saying to the caller, but not the caller. On the other hand, if you are using an iPhone, neither voice will be heard.
No.
You only need to scan all the cards of your group at the beginning of your trip to open the session. The session you open will be saved in your Nubart account, even if you or the travelers close the browser. If there are stragglers, all you have to do is scan their card to add them to the group you have already opened. It's that simple!
Occasionally, group members will need to scan their own cards again to rejoin the session. Don't forget to tell them to keep the card handy!
1) Internet connection
Short, non-techie answer: Your Internet connection does not need to be high if your network is set up properly!
Long techy answer:
If your network configuration (NAT, firewalls, topology) allows peer-to-peer connections for Web-RTC and all participants are on the same WLAN, the actual voice signal doesn't use the Internet connection. That's because each listener has a peer-to-peer connection to the speaker once the connection is established. The Internet connection is only needed to manage each connection, which doesn't require much bandwidth.
2) WIFI/WLAN
The LAN must be able to handle the number of concurrent users (subnet mask) and the WIFI hotspots must be able to handle the bandwidth and number of users. Please ask your technician to ensure this!
If the network configuration does not allow peer-to-peer connections for Web-RTC, there is a fallback system to handle such a scenario. But this fallback uses a relay server (Turn server) on the Internet and would require the voice signal to go through the Internet (see 1.), so we recommend to allow peer-to-peer on your network.
Alternatively, you can set up a local Turn server. If you want to do this, please contact us as it requires some extra work on our part.
