Retail Payment system

Technology Roadmap

Roadmap Overview

The U.S. financial system processes millions of transactions each day to facilitate purchases and payments. In general terms, a payment system consists of the means for transferring money between suppliers and users of funds through the use of cash substitutes, such as checks, drafts, and electronic funds transfers.

A payment system is a system exchanges / trades value by changing the ownership of money. It consists of a set of instruments, banking procedures, and, typically, interbank funds transfer systems that ensure the circulation of money. These systems allow for the processing and completion of financial transactions.

From the typical consumer’s perspective, making a payment is simple. A person swipes a card, clicks a button, or taps a mobile device and the payment is approved within seconds. However, the infrastructure and technology underlying the payment systems are substantial and complex. To simplify, a payment system has three parts (see Figure below).

Design Structure Matrix (DSM) Allocation

The DSM of the Retail Payment System provided by banks is depicted in the image below.

Object Process Model (OPM)

The OPM diagram captures the main object of the roadmap, its decomposition into systems (squares), as well as the main processes (ovals).

Figures of Merit (FOM)

The table below show a list of FOMs by which can assess a Payment System

Class	Figure of Merit	Units
Performance	Value of transactions processed per annum	[US$]
Productivity	Number of transactions processed per annum	# of transactions processed per country, per individual or business client type
Efficiency	Average cost per transaction	[US cents]
	Transaction settlement period	[Seconds]
Reliability	System downtime per year	[Seconds]
	Payment conversion rate	[%]
Safety & Security	Sustainability ratio	[%] of Gross Operating Income that is spend on events to ensure the system is safe, secure and available to users. Within this ratio falls fraud related losses, system availability, cyber attacks, non-compliance events and user security.

Company Strategic Objectives

We identified strategic objectives that can stand the test of time. We want our clients to understand our that we are constant, unchanging, something they can depend on. As technology improves, we can change the respective FOM and targets, without changing our strategic objectives. The table below shows our strategic objectives:

Strategic Objective	Alignment and Targets
An efficient payment system that processes and settles transactions in near real-time.	Currently we have a transaction settlement period of 1 day and aim to decrease this to 90s.
Our clients trust us to process their transactions in a safe and secure manner where they do not lose money.	We aim to maintain a Sustainability ratio that is lower than our 0.1% target of Gross Operating Income.
Our clients can make payments to anyone, anywhere.	We continue to grow the number of payments we process pa to more than [1bn], servicing more than [750k] individual and [10k] business clients in [76] countries. Our goal is to process 1% of all payments made as reported by the Bank of International Settlements (currently we are at 0.57%).

Technical model

For payment systems, the technologies already exist to process a payment near real-time (near real-time is real time with network latency).

The main challenge is to comply with the regulatory requirements placed on the industry. Various acts are relevant to the payment industry, including Anti-Money Laundering (which is used to combat drug trafficking), Cross-border Terrorist Financing (used to combat terrorism) and the Foreign Account Tax Compliance Act (where the US requires all non-U.S. foreign financial institutions to search and monitor their records for customers with a connection to the U.S.).

For our company, the following strategic objectives were determined for the company to be pursued in the following year:

• Improve the transaction settlement period to less than one day; and
• Decrease operating costs by 10% whilst improving the sustainability of the system (the relevant FOMs for this objective are to decrease average cost per transaction whilst decreasing / maintaining the Sustainability ratio)

A two-level decomposition was performed to identify which technologies can be enhanced to achieve these objectives as per below:

Below are descriptions for each of the projects:

#	Level 1 FOM	Project Name	Description
1	Transaction settlement period	Block chain	Build new blockchain infrastructure to facilitate fast, secure, low-cost local and international payment processing services (and other transactions) through the use of encrypted distributed ledgers that provide trusted real-time verification of transactions without the need for intermediaries such as correspondent banks and clearing houses
2	Transaction settlement period	Fed Interbank real-time payments infrastructure	The Fed has committed to a new real-time payments platform that would enable financial institutions in the U.S. to clear and settle transactions in virtually instantaneous fashion to be completed by 2023/2024. Our payment system is to integrate with this new platform.
3	Sustainability ratio	Application Programming Interfaces (APIs)	Open Banking will require financial institutions to open their data for third parties to access and consume. By developing standardized APIs, we can ensure our clients data is safe, secure and only the relevant data is provided when third parties requires access.
4	Sustainability ratio	Biometric Authentication	Clients can access our payment systems by using fingerprints (opposed to PIN)
5	Sustainability ratio	Voice recognition	Clients can access our payment systems by using their voices (opposed to PIN)
6	Sustainability ratio	Facial recognition	lients can access our payment systems by using their face (opposed to PIN)
7	Sustainability ratio	Advanced analytics - fraud monitoring	The current false-positive irate in fraud detection is greater than 40%. This should be reduced to 20% by using more advance analytical techniques, and create resource capacity to investigate actual fraud cases. Advanced analytics can also detect and take mitigating action in real-time to decrease client related fraud losses by 30%.
8	Sustainability ratio	Advanced analytics - AML/CTF monitoring	The current false-positive irate in AML/CTF detection is greater than 90%. This should be reduced to 60% by using advance analytical techniques.
9	Sustainability ratio	Red team	Recruit a red team (consisting of ethical hackers) to continuously identify and attack cyber security vulnerabilities.
10	Sustainability ratio	Digitally integrated risk management	Integrate respective risk monitoring performance indicators into system processes and automate reporting.

Each project was quantified and a "Net Impact score per dollar". This equation utilizes the following variables:

• The project cost (C) is estimated, utilizing an algorithmic project management software application (example SEER);
• The percentage feasibility (F) of project success is determined by combining expert SME and technologist opinion;
• The direct benefits (D) are real monetary benefits (e.g. increased revenue, cost reductions) to be realized by the project which the project sponsor commits to realize; and
• Indirect benefits (I) are other risk or economic related benefits which will not directly impact the company’s net profit, but will create a more sustainable system (e.g. reduce the risk profile of the system, avoid regulatory fines and losses, etc.)

The "Net Impact score per dollar" was calculated as follow:

This resulted in the following tornado diagram being generated:

Based on the assumptions and commitments in the respective scores, the following benefits will be realized at the Level 1 FOM level:

• The transaction settlement will decrease to less than a day; and
• Enabling an open banking API capability will decrease the likelihood of incurring a GDPR fine or penalty and improve our sustainability ratio by 0.5%.

Patents and papers

• MIT Libraries yielded the following results for a “Payment System” search: Books and media (88,910), Articles and journals (131,263) and Archives and manuscripts (62)

Other credible sources of public information include:

• US Federal Reserve (Fed)
• World Bank Group
• Bank of International Settlements (BIS)

It is worth noting that very little information is available about the respective technologies and systems that is used within a payment system. This is likely to the highly confidential nature of these systems where people's money must be protected from cyber criminals.
