Tikkie is a mobile payment provider service based in The Netherlands. Tikkie is developed by ABN Amro and allows anyone based on The Netherlands, and with a bank account in The Netherlands to access Tikkie.

Tikkie is an online payment app that allows you to forward payment requests to people via WhatsApp, or pay through a QR code. Once you open the request or scan the code, you’ll be asked to forward the money through your online banking.

Region

The Netherlands. You need is a bank account (IBAN) in The Netherlands, and also to be based in The Netherlands.

AFAIK Tikkie is not available to users outside The Netherlands, even if they have an NL IBAN.

Currencies

EUR

Chargeback risk

Low

Size of user base

5 million+ users Over 200,000 Tikkie sent per day 38% settled within 5 mins.

Data requirements

The service allows payments between users though either WhatsApp or sending a QR code.

From a privacy perspective it might be best for users to send a link to the QR code via Bisq trader chat. This would eliminate any need for providing other data eg phone / email.

Verification

TLSNotary may be used as payment method is bank based. App only banks will require screen recording / screenshots for payment proof.

Duration

Payment link is sent. When user makes payment it is instant.

Fees

Subscription fee is €5,00 per month to make Tikkiw payment requests. This includes 20 Tikkies. After that is is 0.25 Euro per Tikkie.

When you send a Tikkie to several people, you can request a maximum of € 2500 euros at the same time . Per individual person you can receive a maximum of € 750 per Tikkie request.

The maximum amount within 24 hours is also € 2500 per Tikkie account. The total amount in one day may not exceed this, otherwise the payment will be refused.

Each bank however may establish its own limits, within these limits, for its clients.

Hi @pingiun I would be grateful if you can give me feedback on the above.

Particularly if we can just have users send a link to the QR payment request via Bisq trader chat?

Also not 100% on fees. Do you pay 5 Euro a month to access the service?

Hi @pingiun I would be grateful if you can give me feedback on the above.

Of course

Particularly if we can just have users send a link to the QR payment request via Bisq trader chat?

The Tikkie app doesn't use QR codes itself. By default it presents you with the option to share a message with link via WhatsApp because this is the most used messaging system in the Netherlands. However it also has the regular share menu on Android or iOS which allows you to copy the message. Then they have to send it to the computer they run Bisq on in some way. The message includes something like "Please pay me for 'payment reference'" and includes a link to the Tikkie website.

The Tikkie website in turn refers you to your bank to make an iDEAL payment. The iDEAL payment may include a QR code (depending on their bank), but that is not relevant for Bisq, users will be familiar with this as it's just how we do web payments.

To clarify, only the website url Tikkie gives you is needed to make the payment.

Also not 100% on fees. Do you pay 5 Euro a month to access the service?

No fees are needed. Tikkie is a free service for non-commercial use. As long as Bisq users just use Tikkie like normally on their phone they don't need to pay fees. I have no experience with the commercial features of Tikkie, but along with the fees I imagine they require a commercial bank account and a company registration (and VAT code


My screenshots and walk through the process from the previous issue might come in handy for implementors or arbitrators/mediators. I can also make more screenshots if desired.

pazza83 commented 3 years ago

Hi @pingiun thanks for all the info.

I would be in favour then of not including contact number. Users can send their payment link to the BTC buyer for payment. This seems preferable in terms of privacy.

In the event of a dispute however what can be provided by way of proof.

For example.

Alice offers on Bisq 0.01 BTC using Tikkie for €500. Bob takes offer. Alice sends Bob a payment link. Bob sends €500 to his friend. Alice opens a dispute Bob says I sent the €500

or

Alice offers on Bisq 0.01 BTC using Tikkie for €500. Bob takes offer. Alice sends Bob a payment link. Bob sends €500 to his Alice using the payment link. Alice opens a dispute to say she never received the €500 Bob says I sent the €500

What information can be provided in the Bisq payment method account to prove the source and origin of the funds. Would IBAN be ok? Is the Tikkie payment linked to an IBAN that both users can see?

pingiun commented 3 years ago

On Alice's point of view, she can show that the Tikkie item she made has not been paid for yet. In the below two screenshots you can see what this looks like:

IMAGE 2021-05-06 09:48:49

Here you can see the list of Tikkie items I created. The top item labeled 'Bisq' shows that the request is still open. The two items below that show how many people paid for this. Paid 6 times and 5 times respectively.

When I click on the top item you get this view:

IMAGE 2021-05-06 09:50:16

It reads "Er is nog geen betaling bevestigd" which means "no payment has been confirmed yet".

However for these two screenshots it would be possible to delete the original item that has been paid and create a new one that has not been paid yet. So to proof lack of payment, a screen recording would be needed where the receiver clicks the QR code button (in the bottom of the second screenshot). The link could also be shown, but I think this is too much hassle as it requires the user to use the share action to a place where the link is visible in the video. Because the QR code is immediately visible I think this would work better. This QR code would then have to decode into the originally sent URL.

The QR code screen for reference: IMAGE 2021-05-06 09:57:08

This code decodes to just the payment link: https://tikkie.me/pay/kpg0efpt6ht28f7v2jsp This should be the same as the original link sent by Alice.


From Bob's point of view, a bank transcript is needed. For this I made a Tikkie and paid it myself. My banking app shows this for the transaction information:

IMAGE 2021-05-06 10:05:39

As you can see the payment is to Abn Amro Bank Nv (the parent company of Tikkie). This is because the actual payment is done via iDEAL on the Tikkie website. However, they always includes the Tikkie description and receiving IBAN and name into the payment reference. (Shown at "Omschrijving") I blacked out part of my IBAN in this screenshot, but this can clearly be used to proof payment if the IBAN is saved into Bisq.

Allice will also be able to see the sending IBAN on her end in the same way. For reference, here is how it would look for Alice (showing +€5,00):

IMAGE 2021-05-06 10:09:05

I see an issue here because some bank apps don't allow screenshots on Android. In that case a desktop could be used show the bank transcript, but on desktop it's easier to doctor webpages of course.

pazza83 commented 3 years ago

@pingiun thanks again for all the useful info.

I think including IBAN in the payment account should solve the problem of proof.

If a website proof is needed then pagesignercan be used.

Many thanks for the detailed screenshots. Is it ok to include them when I am creating the wiki?

pazza83 commented 3 years ago

Here is the XD for Tikkie, it should be straight forward to add (main difference is buy/sell limit should be set to 0.05 BTC):

Payment method - Tikkie

That is fine, I would appreciate it if you could anonymize them.

Information required for Bisq software strings:

Hi @jmacxx here is the information for the strings.

Let me know if you need anything else:

Special info about any of the inputs required for creating the payment account:

To use Tikkie you need a bank account (IBAN) in The Netherlands and to be registered for the service.

When you send a Tikkie payment request to an individual person you can ask to receive a maximum of €750 per Tikkie request. The maximum amount you can request within 24 hours is €2,500 per Tikkie account.

Each bank however may establish its own limits, within these limits, for its clients.

Traders on Bisq should be aware of their limits. If you trade over the above limits your trade might be cancelled and there could be a penalty.

Special items to be aware about when sending payments (for BTC Buyers):

Please request a payment link from the BTC Seller in trader chat. Once the BTC Seller has sent you a payment link that matches the correct amount for the trade please proceed to payment.

When the BTC Seller requests a Tikkie payment the maximum they can ask to receive is €750 per Tikkie request. If the trade is over that amount the BTC Seller will have to sent multiple requests to total the trade amount. The maximum you can request in a day is €2,500.

Each bank however may establish its own limits, within these limits, for its clients.

Traders on Bisq should be aware of their limits. If you trade over the above limits your trade might be cancelled and there could be a penalty.

Special items to be aware about when receiving payments (for BTC Sellers):

Please send a payment request a payment link to the BTC Seller in trader chat. Once the BTC Buyer has sent you payment please check their IBAN detail match the details they have in Bisq.

When the BTC Seller requests a Tikkie payment the maximum they can ask to receive is €750 per Tikkie request. If the trade is over that amount the BTC Seller will have to sent multiple requests to total the trade amount. The maximum you can request in a day is €2,500.

There are two places in the trade process that we typically show a popup:

The problem I have with this block of text, is that if shown at make/take offer stage, it can confuse the user since it appears to be instructing the user: "Please send a payment link..." which is not even possible. If it is shown at the pay/receive stage of a trade, the other information about "be aware of bank limits" is moot.

Ideally, if the payment link information could be worded in such a way as to indicate that it applies in the future, as opposed to right now it would make sense to display at the make/take offer stage which is typically where these popups have been placed.

@m52go WDYT?

I suppose it would also be possible to split the information, some displayed at make/take and the other displayed at pay/receive. :disappointed: That would introduce extra complexity to the workflow (from a dev/maintenance perspective).

m52go commented 3 years ago

Strictly speaking, the text can be made to work (see below). But I'm not sure it is ideal for users, since this 1 small box covers 2 distinct bits of information (sending link + limits). Two boxes would be ideal. But given the extra complexity, maybe it can be considered if the payment method sees strong usage.

For 1 box:

BTC seller will need to send BTC buyer a payment link in trader chat (this will be possible as soon as the deposit tx confirms). BTC seller should check that the BTC buyer's IBAN matches the one specified in Bisq.

When the BTC seller requests...
