For every 10 payments you make, bonsai plants a tree. To do this, we work with Eden Reforestation Projects. They plant trees in their partner countries where they think it’s needed most.
It is indeed our intention to add more personalization options to the app in the next phase.
bonsai is a payment institution licensed by the National Bank of Belgium. That should be all the assurance you need that the app meets all standards for the security of your account, data and money. But, if you’d like to know more go here.
Payments are securely made through touch ID, facial recognition or a 6-digit PIN code number.
For security reasons, we ask you to reconnect your bank account every 3 months. This is necessary in order to continue using and paying via the bonsai app. Think of it as logging into a device that does not belong to you. We just want to make sure that you have full control over what happens.
Open the bonsai app.
Scan the salesperson’s QR-code
Confirm your payment using touch ID, face ID or your 6-digit PIN code.
There is no cost to use the bonsai app and the bonsai Mastercard. bonsai is a completely free way to pay securely in stores and online anywhere in the world.

No, bonsai will never charge you extra!
‍
Please note, however, that some banks will charge additional costs if a SEPA Direct Debit cannot be executed immediately on the account. bonsai is not responsible for these costs.
‍
A SEPAÂ Direct Debit does not mean that we will be taking monthly charges from your account. It means that when you make a payment through the bonsai app or with the bonsai Mastercard, you give us permission to withdraw the money from your account. At no point will bonsai ever withdraw money from your account without your approval.
‍
1. In the bonsai app, go back to 'link your bank account'
2. Select the correct bank (e.g. are you a Hello Bank customer, select Hello Bank, and not BNP Paribas Fortis)
3. Click 'via card reader' (not Itsme)
4. Complete the steps
‍
Go to the ING app and link your private account, not your business account.
‍
Make sure your banking app is up to date. Go to the App Store or Play Store on your smartphone and download the latest update of your banking app.
‍
The bonsai app links to your bank account directly, not to a credit card separately.
‍
Absolutely! You can never pay without Touch ID, Face ID or your smartphone's unlock code. This makes paying with your smartphone even more secure than paying contactless with your bank card.
Mangrove trees, which can only grow in tropical regions and climates, absorb up to 4x more carbon than an average forest in Belgium. Mangroves are so efficient because of their dense underground root system. Madagascar is furthermore an ideal place for mangrove reforestation, as the orginal natural forests have been extensively destroyed in recent years.
Don't worry. The bonsai app takes up very little memory space on your smartphone. It is a small file of less than 100MB.
‍
Planting trees is one of the most efficient ways to reduce our CO2 levels. As an added bonus, we improve our planet’s biodiversity and provide a fair wage to the local community by planting trees with our partner Eden Reforestation Projects.
The app currently relies on an average CO2 emissions of 15 tonnes per year, of which 14.5% is allocated to transportation and mobility (source). The app does not currently allow for personalization of consumption, and thus indicate, for example, flying more or less than the benchmark. With the 15 tonnes, we assume the "average" Belgian.
Ruben Ceulemans, PhD in ecology (University of Potsdam) and Data Scientist at bonsai.
This refers to all road infrastructure, all public buildings such as schools, hospitals, libraries, etc.
If all Belgians would participate in the #bonsaichallenge, we could plant about 550 million mangrove trees, which amounts to about 550 km2 of forest.
a) Reforestation is a good, natural way to reduce CO2 levels in our atmosphere. Young trees need a lot of CO2 as they grow. Although, of course, emitting less CO2 still remains the best option for the climate.
b) Reforestation of mangrove forests in particular has other desirable effects on the environment: conservation of biodiversity by increasing the natural habitat of plant and animal species, water retention, water desalination, erosion control, protection from storms and tidal waves, and job creation (source). Â
c) CO2 offsetting is not an exact science. Some see reforestation as a good way to offset carbon, provided the reforested areas are protected from destruction for long enough (at least 50 years). By then, hopefully, we will have found a solution to reduce our consumption of fossil fuels. Â
‍
a. Mangrove trees, which can only grow in tropical regions and climates, are among the most efficient resources in terms of capacity to absorb and store carbon. A mangrove forest absorbs up to 4x more carbon than an average forest in Belgium (Donato, D. C. et al. Mangroves among the most carbon-rich forests in the tropics. Nature Geosci 4, 293-297 (2011).). Mangroves are so efficient because of their dense underground root system. Madagascar is also an ideal place for mangrove reforestation, as the original natural forests have been extensively destroyed in recent years. Â
b. In Madagascar, the destruction of huge tracts of natural forest has led to significant habitat degradation. The mangrove forests that were destroyed actually performed several functions crucial for agriculture (protection against erosion, desalination of water, etc.). Reforestation of mangroves will therefore not only remove much more CO2 from the atmosphere than replanting an average Belgian forest, it also does not conflict with current local land use, on the contrary, it will even help restore degraded agricultural areas.
This is a calculation based on the total duration of the growth phase of a tree, which is on average 25 years. That is, it takes an average 25 years for a tree to grow to maturity. It is mainly during this growth phase that a tree absorbs and stores a lot of CO2, about 300 kg of CO2 per tree.
We contribute to the environment, of course, but it is also a way to show potential new bonsai users how easy it is to do something good for the planet and have a positive impact.
a. A major problem with reforestation as a compensation strategy is the conflict with other land uses. In order for an area to be sustainably reforested, it must be protected as a forest for a sufficient period of time. Belgium has a very high population density. Especially Flanders is highly urbanized and the non-urban areas consist mainly of agricultural land. Therefore, reforestation in Belgium would likely involve the reallocation of significant tracts of urban or agricultural land. Â
b.Cf. answer to "Why exactly are you planting mangrove trees in Madagascar?"
a. We donate 10% of our revenue to Eden Reforestation Projects.
b. Eden, founded in 2004, is a non-profit organization that works in developing countries to rebuild natural landscapes destroyed by deforestation.
‍
Yes, we do. Also when we order marketing material, we offset the CO2 emissions as much as possible.
It is not! Apple Pay is completely free.
You can use Apple Pay with any device (iPhone, iPad, Apple Watch, Mac) listed on the Apple Support page. (https://support.apple.com/en-gb/HT208531)
For safety reasons we ask you to re-link your bank account every 3 months. This is necessary to keep paying with Apple Pay. Think of it like logging in to a device that isn’t your own – we just want to make sure you have complete control over what’s happening.

Bonsai offers a credit card with ALL benefits and NO downsides.
This card is completely FREE.
It works like a REGULAR BANK CARD. The money is withdrawn from your account shortly after you made a payment, not at the end of the month.
Beware. This credit card does not offer insurance.
The EU tightened security on online payments in April 2021. This means that payments will require a Digipass or other security measures. We have chosen to ask  security questions and to enter a unique code that will be sent to you via SMS. This way you can pay safely anytime, anywhere.
This is because the bonsai card makes use of the Mastercard credit network to process your payments. We don’t offer credit the way Mastercard does. You can only spend as much money as you currently have in the bank account linked to the bonsai app (see “bonsai spending limit”).
The bonsai Mastercard is completely free.
It takes anywhere from 1 to 3 business days for your money to be withdrawn from your bank account, depending on your bank.
At the moment, not every bank has the PSD2 connection capabilities to offer the open  banking services that allow for Apple Pay to work. Do you want to know if your bank supports Apple Pay? Send us a message via the bonsai app.
When you request to deactivate your account, we will automatically block your virtual bonsai Mastercard. This means it can no longer be used, nor reactivated.

First, make sure your bank account is linked in the bonsai app. Then, when you make a payment with your trusted bank card at one of our affiliated merchants, you will automatically earn Leaves in the bonsai app. Once you've accumulated enough Leaves, you can claim your reward in the store.
When you have accumulated enough Leaves you can claim your reward in the bonsai app. You can do this in two ways.
1. Go to 'Rewards' (at the bottom of the home screen), click on the gift icon, select the reward you wish to claim and follow the steps on your screen.
OR
2. Go to 'Rewards' (at the bottom of the home screen), click on the case where you want to claim the reward, press 'claim' at the bottom and follow the steps on your screen.
‍
By default, we retrieve the transaction summary once a day. You may not see your Leaves until the next day. Do you want to see your Leaves right away? Just press the 'Recalculate' button and your Leaves will be recalculated immediately.
Sometimes it takes additional checking by us to see if the payment was effectively made to the correct merchant.
Leaves expire when you have not made a payment with the merchant for more than a year.
Unfortunately, it is not possible to claim the reward again. We are also unable to reclaim the reward for you. After claiming the reward in the app, you have five minutes tonshow that screen to the cashier(s) and receive your reward.
‍
This is a code by which the merchant can verify that the reward is a correct bonsai reward. The merchant may request this code.
The Leaves are calculated per euro you spend. If you have spent 2.50 euro, then you have earned 2 Leaves.
Definitely. Go to 'Rewards' in the bonsai app (at the bottom of the home screen) and click on the logo of the desired merchant. Here you will find an overview of the number of Leaves saved at that merchant.
‍
Your cashback reward will be paid within 3 working days to the linked account you used to make the payment.
‍
Your claimed cashback reward will appear in your bonsai app immediately.
You can already claim the green rewards, for which you have enough Leaves.
The yellow rewards cannot be claimed yet, as you do not have enough Leaves yet. Keep on saving!
‍
This is a reward that you can only claim once. You cannot use this reward more than once.
There are no costs involved to use the bonsai app. bonsai is a completely free way to pay securely in stores and online anywhere in the world.
