PSD2 overview and requirements

PSD2 timeline

European Commission proposes to

review the PSDPreparations

EU parliament agrees to the

revised directive Law comes into

force in Member States + 24 kk

EBA's technical PSD2 recommendations

Main PSD2 objectives● Contribute to a more integrated and efficient

European payments market ● Improve the level playing field for payment

service providers (including new players)● Make payments safer and more secure● Protect consumers● Encourage lower prices for payments

Source: http://europa.eu/rapid/press-release_MEMO-15-5793_en.htm?locale=en

In practice the directive concerns almost all sorts of e-payments, not just online payments!

PSD2 widens the scope: new services and new players

• Telecom operators ● Physical products and services purchased

through a telecom operator

• Payments outside the EU● PSP must provide the customer clear

information about prices and payment terms● PSP operating in the EU has a responsibility

in international payments

New and changing roles in the value chain

• Account Servicing Payment Service Provider (ASPSP)● Consumer's bank, current issuer

• Payment Initiation Service Provider (PISP)● Initiates the payment process, seller or PSP

• Account Information Service Provider (AISP)● Consolidates customer's data, ”cross-bank”● AISP can be a totally new actor

PSD2 defines interfaces between various actors and opens up the value chain for new actors!

Notes about PSD2 payments• PSD2 expands the reach of online payments

● As many as 60% of the European consumers don't own a credit card

• PSD2 simplifies online payments● Potentially less players in the value chain● Potential savings to merchants and consumers

● New entrants may enter the payment market● PSD2 accelerates competition in payment services● ASPSPs must open APIs to other PSPs

Notes about AISP

● AISP can have a significant position in the PSD2 world

● A customer can get all bank services from one place

● The whole of banking data can be collected into one place

● A good chance to create added value:

”cross-bank”, ”cross-product”, ”cross-sell”

€ € €

Responsibility of the PSP

● Strong customer authentication ● Must include elements linking the authentication

to a specific amount and payee (dynamic code)

● User privacy● PSP must protect users’ personalised security

credentials.

● PSPs are required to find evidence against fraud● If the customer denies a payment transaction, PSP is

obliged to provide proof - or refund

SECURE ACCESS – GOOD CUSTOMER EXPERIENCESECURE ACCESS – GOOD CUSTOMER EXPERIENCE

Customer authorizes third party service to act on behalf of her or him.

An explicit consent from user needs to be received.

One-time or frequent access.

User must be able to cancel given authorization any time.

Authorization needs to be fine grained and user needs to understand the scope.

Confidentiality of customers’ credentials.

No complicated enrolment for third party providers.

PSD2 REQUIREMENTS FOR ACCESS CONTROL

OAuth 2

Proven and open access management standard, which supports delegated access on behalf of

resource owner.

• Strong authentication• Approval of scope

• Customer never shares credentials

• “Valet key”

Delegated access to API’s

Expect technical recommendations to be available during spring.

Any ongoing architecture or technology projects should already consider coming API requirements.

OAuth 2, although not yet proposed or decided, is at least a good choise for API access managemet.

Understand that OAuth 2 is not a strict standard:– Maturity in different access management products varies.– Secure implementation requires skills and experience.

WHAT NEXT?
