Siirto is a mobile payments system allowing instant transactions between users through mobile phone numbers. Operating only in Finland, Siirto boasts of over 1.5 million regular users. This is an ideal banking option for Finnish players who want to play video slots and other games in online casinos accepting Siirto. Very low commissions (1%) and high transaction limits are some of the reasons for Siirto's popularity in that country.

General information about Siirto

Siirto is a real-time mobile transfer solution operating in Finland. This is a young payment system launched in March 2017 as the country’s first mobile payment platform. It was developed by Automatia (owned by Nordea, OP, and Danske Bank) in collaboration with Tieto).

This payment provider features an important role and place in the national financial eco-system. In 2022, the Bank of Finland Payments Council started promoting the creation of a national account-based payment platform.

A member of the executive board of the company said that the country had to ensure the independence and integrity of the domestic financial system, that is why they entrusted Siirto with developing and launching an instant payment solution. Today, this is one of the trendiest and widely distributed options with Finnish players. Therefore, most online casinos targeting that country offer Siirto among the available banking methods for deposits and cashouts.

The Siirto payment system enables easy payments via mobile phone, via a reliably identified phone number. For example, you can send the amount you want to an online casino. You select their contact information from your phone in your own application, add the amount and pick ‘Siirto’. The payment will appear in the online casino’s application immediately, even if they use a different bank.

How to create a Siirto account

Siirto itself is not a standalone app where you open a separate account. Instead, it is a payment feature integrated into participating Finnish banking applications. To start using it, you must already have an active account with a Finnish bank that supports Siirto.

1. Download your bank’s official mobile banking app (OP, Nordea, Danske Bank, or other supported institutions) and log in using your online banking credentials.
2. Locate the “Siirto” or “Mobile payments” section within the app. You will be asked to activate the service and link it to your phone number. This number will function as your payment identifier.
3. Confirm activation using your bank’s strong authentication method. Once enabled, you can send and receive instant payments directly through your banking app.

How to deposit to online casinos with Siirto

Finnish players who want to play for real money and cash out real winnings must first sign up in a reliable Siirto casino (see the best Siirto casinos on this page). After that, you should check the limits set by the casino. As a rule, the minimum deposit with Siirto is €10, but it can vary across gambling sites. When you are ready to top up your account in the casino, do the following:

1. Find the banking page in the casino (Deposits) and browse the list of available options. It normally has 5 and more options, one of which would be Siirto.
2. Tap the Siirto logo and enter the amount you want to send to the online casino.
3. The online casino will ask you to fill in some personal information, after which you will be taken to the Siirto platform where you complete the transaction.

Confirm the transaction by entering the OTP code in the casino. The deposit will reflect in your account almost immediately, and you can claim the first deposit bonus if the Siirto online casino offers it (most do).

How to withdraw from online casinos with Siirto

Before you proceed to cashing out, you must check the withdrawal limits in the terms and conditions or on the Withdrawal page. Besides, you must check whether your servicing bank whose app you use for Siirto transactions accepts payments through this option. Follow these steps when you are ready to initiate a withdrawal request from your Siirto casino:

1. Go to the Withdrawal page and find the Siirto option.
2. Check the limits and enter the amount you want to cash out.
3. You must enter your phone number tied to the Siirto platform, after which you will be taken to the mobile banking app where you complete the transaction.

KYC in the best Siirto casinos

Most casinos in Finland operate under the local Lotteries Act, except for offshore casinos. According to the licensing requirements, a legal online casino must conduct KYC checks for its registered members.

To this effect, players who have created an account in a Siirto casino must submit a few documents to prove their identity and place of residence, including the copies of their passports (a driving license), a utility bill, and so on. Siirto online casinos usually verify the information within 3 to 5 days, after which the player is deemed compliant.

Siirto transaction times and fees

Deposits made through Siirto are typically credited instantly, so you can begin playing without delay, which is a real plus compared with slower traditional bank transfers.

Withdrawals, where supported, are also processed quickly by the Siirto system itself, although the actual time until funds hit your bank account can depend on the online casino’s internal processing procedures, often ranging up to 24 hours after approval.

On the cost side, Siirto does not charge its own fees for casino deposits or payouts, and most operators follow suit, meaning you keep more of your funds for gameplay. That said, individual banks may still apply nominal charges under specific account terms, so it’s prudent to check with your provider beforehand.

Additionally, there’s usually a daily cap (around €1700) on how much you can send via Siirto.

Games in the best Siirto casinos

Finnish players who want to get registered in Siirto casinos will find over 10,000 different games from the best providers. The scope and variety of games is really impressive as they are broken down into video slots (the majority of any game collection), live dealer games, table games, crash games, instant-win lotteries, keno, video poker, and other casino games.

Most game types, especially video slots, qualify for bonus wagering, so you can easily claim a deposit bonus or free spins in a Siirto casino and get a powerful boost to your initial deposit. You can normally use game filters to refine the game display (e.g., by provider, type, feature or alphabetically) and get the best gambling experience in your favourite Siirto online casino in Finland.
