PSD2 explained and why you should care



Since the revised ) was proposed by the European Commission back in 2013 it has already created widespread of disruption in the European payment market. New payment processors are popping up almost daily, and the big banks are clearly moving to secure their positions before the directive comes fully into force in September 2019.

Why you should care about PSD2

You probably don't run your own bank, or think that you would have any interest in using security mechanisms evaluated based on the requirements in the PSD2. But even if you don’t process payments yourself there are some good reasons for taking the PSD2 into account! As long as you’re selling a service or a product, and either you or the buyer is in a EU country, the PSD2 will have an impact on your business.

You’re surely aware of one of the key benefits of the PSD2: it will enable end users to initiate online payments directly from their bank account, without going by a credit card. This offers the possibility of significantly reducing costs, but there is one major challenge: What happens when there is fraud, and the payer requests a chargeback?

Why PSD2 is a good thing

Clearly, this will be a great challenge for merchants in the future. The might have to refund the payer, but the money has to come from somewhere. If there is one thing that banks and payment service providers hate, it's giving away their own money! So, if you’re a merchant it becomes even more important to be sure that your transactions are valid.

The first case happens all the time. The Okay mechanism gives you the possibility to show that it wasn’t some kind of bug or mistake on your part, and that the order was really placed as you have it documented.

The second scenario is more scary: What if targets your app, and tries to enter fraudulent orders through it? In this case it is very easy for the payer’s bank to claim that this is your liability, and that the refund should come from your funds. Using the Okay mechanisms for verifying transactions will make it nearly impossible for you to be the target of automated attacks. Even if an attack is carried out, the will give you a heads-up, so that you can delay the delivery of the service, avoiding fraud all together.

The Okay solution was initially created for banks and payment processors, in order to let them do . It does not protect against a stolen identity and payment details being used for an order, but then this is the responsibility of the account service provider.
