Clearing

Clearing is the process of :

• Routing, transmission, reconciliation and, in some cases, transfer orders confirmation prior to settlement

• Netting of orders and establishment of final positions for settlement.

• The settlement in the central bank (Target2) completes the processing of a transaction by discharging the obligations of one PSP to another through the transfer of funds

Drivers of Instant Payments


The digitalization of our economy, with the spread of smartphones and of

electronic commerce, entails a general acceleration of payments.

New technologies stimulate

innovation in payments, and

contribute to the expectation for

instant payments.

On the one hand, new

technologies drives the

evolution of customer habits,

who take for granted the ubiquity,

any time anywhere, of internet

shopping.

Customers also expect to pay for

and receive their purchases as

fast as possible.

Suppliers, on the other hand,

wish to retain the certainty to be

paid as soon as they release

their goods and services while

valuing the increased simplicity of

e-money.

Definition of Instant Payments


According to the ERPB (European Central Bank), instant payments are the

closest substitute to cash : the transfer of money is immediate and available

24/7/365

When credit transfers or card payments are used, funds take up to one business

day or more to be available on a beneficiary’s account.

The clearing process of instant payments is different as the processing,

clearing and (potentially) settlement of payments take place on a transaction-by-

transaction basis as soon as they reach a PSP system, i.e. in real time end-to-

end.

The STET’s new Clearing platform


A new paradigm

Moving from a « closed user group » services model located in two datacenters

(active/passive) built on a « Shared Memory » architecture based on an

"asynchronous batch file processing“ solution...

…to a unified platform distributed over 3 datacenters (extensible), supporting

all existing and future Clearing services : SEPA(EU), Card & Legacy Payments,

Instant Payments based on a “real time transaction-by-transaction

processing” solution
