No matter how you change the wiring, there is one major issue – ultimately, you need to take money from one bank and pay it into another bank. Still, the world is changing and alternative payment options are springing up like mushrooms after the rain. Let’s see where they are heading.

Payments, as the name would suggest, means taking money either physically or electronically from one place and paying it to another. We usually think of it as physical or online card payments but it can also refer to mobile wallets, direct bank-to-bank transfers for salaries, and even crypto-currencies. However you think about it, payments represents one of the largest marketplaces on the planet.

For example, Visa handles over $5 trillion in total global volume annually. At two percent per transaction, that’s $100 billion a year, but most of that two percent goes to the issuer, the bank name on your card. Visa takes just a few basis points* (bps) to provide the “plumbing” that connects all the banks together.

There are several roles in a typical payment: the cardholder, or people like you and me; the merchant who you are buying from; the acquirer, or the company providing the POS [Point of Sale] system; the network, like Visa or MasterCard; and the issuing bank that provides the card for the cardholder. For the merchant to get money from the cardholder, the acquirer, network and issuer act as intermediaries, taking little bits of that two percent off the transaction. It can get more complex as we add affiliates, foreign exchange (FX) and sales commission and more. As you can imagine, with tens of billions of dollars flowing through networks like Visa every day, just 1bp is worth millions. Hence, there is a thriving marketplace in providing alternative payment options.

Legacy and regulation

No matter how you change the wiring, there is one major issue. Ultimately you need to take money from one place, a bank, and pay it into another, another bank. Banks are legacy institutions and their technology reflects that. While almost every investment bank on the planet uses Java on Linux, they have literally hundreds of systems, many from previous mergers or integration into systems that are geriatric. At one major bank where I worked, we found over 40,000 database instances. Even the smallest project costs millions in such an environment, not just for the PowerPoint jockeys, but the developers who must integrate into over a dozen databases and systems. Banks find it extremely difficult to adapt to new payment methods or provide simple and cheap APIs.

Additionally, at least since 2008, compliance and regulation has buried most banks to the degree that they cannot escape technical debt, and find themselves slowly imploding. The latest directive is PSD2 (Payment Service Directive) and it is a significant headache looming over the banks to implement.

How payments work

We can split payments into two parts: 1) acquiring, i. e. taking consumer funds for merchants; and 2) disbursements, ie. paying funds from merchants out to their supply chain, Salesforce, etc. While closely linked, they usually take place in two distinct parts. When buying something on Amazon, money is credited from a consumer account and settled to Amazon. Then, Amazon pays the vendor separately. There is a good reason for this, and it’s all about compliance and regulation.

If you were to pay the vendor directly your bank would need to know where the money’s going. Equally, if the vendor received large amounts of money from seemingly random accounts, their bank would also need to know where it’s coming from. With Amazon acting in the middle, we simplify some of the compliance and Anti Money Laundering (AML). Amazon can also manage the FX by presenting the price in the buyer’s currency and choosing how to pay.

When a consumer pays Amazon, Amazon’s merchant acquirer, like Chase Paymentech, asks your issuing bank to credit the money from your account, and settles it to Amazon. Then, they instructs the vendor to ship the goods. Amazon actually takes ownership of the goods for a split second to meet regulatory rules. At a later date, Amazon then tallies up the goods sold by the vendor, subtracts commissions etc. and instructs its bank to pay the vendor in his/her currency.

When the vendor doesn’t receive the correct amount of funds, we need to involve the bank. Amazon’s bank supports Amazon’s needs because of the billions of dollars deposited in accounts. When Amazon contacts its bank, the bank has to trace the payment across dozens of databases, logs and messaging systems. Worse still, it usually then goes on to another bank, a corresponding bank, and/or the vendor’s bank. Typically about one percent of payments fail, most errors are related to on-boarding or the vendor putting in the wrong details, not Amazon or the bank. This is made worse in the US where the banking system still relies on checks. It costs the banks millions to service these payments, but they do it to keep the lucrative account.

I’ll drop the Amazon example from here, the same is true for AirBnB, Uber, Lyft, Apple, governments, employers, and anyone making mass B2B or B2C payments.

Accounts aren’t exclusive to banks

We all know that the emerging market in Asia is a gold mine, the problem is that many of them don’t have bank accounts. You might react with shock and horror, but in this day and age you can survive very well without an account. There are hundreds of millions using AliPay in China, M-Pesa in Kenya and several other countries in the area. And of course, there’s PayPal.

My own children have a card called “Osper” which holds their current and savings accounts. My wife and I can control where they can spend their pocket money and they don’t have to carry cash when they shop on their own for expensive items like shoes. It’s all managed from an app in real time. The problem is, none of these are bank accounts that a business can pay from their bank accounts, notwithstanding the fact that these modern types of accounts are only going to become a larger and larger part of the global economy.

Crypto-currencies are not the solution

Whether you’re an anarchist or banker, you will have surely seen the hype around crypto-currencies, with BitCoin at the forefront. I own some BitCoins. I’ve had some since the very earliest days and have made quite a bit of money from them. But that was purely luck. I would have made the same from buying gold or Apple shares at the right time. BitCoins are a minute part of the market, used predominately for porn, drugs and money laundering. While BitCoin can be used to buy coffee and cakes in some places, it’s mostly just a research experiment that a bunch of anarchists took seriously.

Firstly, it takes a good ten minutes to validate a transaction, by which time your coffee will be cold. It’s very limited in what can be transacted due to the 1k limit and the only people who can change that are the few developers who have commitment to change to the code. Let’s just say it’s in the interest of many of the competitive crypto-currencies to make sure it doesn’t change. BitCoin is not controlled by a rich, over-paid banker, backed up by a central bank, a democratically elected government and an army, but rather a few programmers. Where would you put your money?

Blockchain – today’s technology hammer

Blockchain is not the solution to everything. The idea is not new, either. Reverse engineering a blockchain is about as easy as trying to destroy every single copy of the New York Times a week after it’s been distributed across the globe. A ledger is a ledger; it could well be on a blockchain or it could be in a database. Databases can still be encrypted and can also have checksums.

As an architect, I like to solve problems with the right technology, not use a technology to find problems. There are a few interesting features of a blockchain, such as smart contracts. However, all of the traditional problems of CAP theorem etc. still apply to blockchains. Blockchain enthusiasts seem to forget this. One thing is true though, the only blockchain worth using is the permission centralised or de-centralised model. The distributed and un-permissioned model (as used by BitCoin), creates more problems than it solves.

So what is the solution?

Payments will not change overnight. You simply cannot re-route trillions of transactions across a new system and change the entire ecosystem. We’re talking about so much money that it could totally change the global economy in a major way. Traditional banks may struggle to survive. We’ve seen a lot disappear over the last few years and more will follow, although that may have more to do with loosening of anti-trust regulations.

I predict large changes when the US tax model changes and companies are able to repatriate their money back to the US.  What will happen to the banks holding those trillions of US dollars today?  How will they remain viable under current regulation? Brexit will have a major impact on many of the UK banks previously able to count European holdings in the same pool. We’re in for a rough ride in the next few years. Opportunity will come for some, but for many it will be a tough dose of reality.

We will see some of these new accounts and banks starting to provide better and better services. More and more people will start to use apps on their phone to receive salary or make payments and purchases. Some of the more agile banks (almost a oxymoron) will realize this and strip off their retail arm, they may partner or fund one of these new accounts. We see the start of this already with banks closing down high street banks. They will then be far more competitive in providing services such as savings, investments, loans, and mortgages.

To read more about the marriage between software and finance, download the latest issue of JAX Magazine:

Does working in the finance sector pay off for software developers? The answer is “yes”. IT is a must have for most banks these days – a massive change from its previous “optional” status. That being said, if banks are trying to win developers over, why shouldn’t the latter learn a bit about this sector?

The technological needs of the finance industry include aspects such as Continuous Delivery, Java, Big Data, machine learning, low latency etc. By embracing these elements, the finance sector can change the status quo and co-exist with what appears to be a fierce opponent: FinTech. How should banks respond to FinTech? We invite you to open the magazine and find out.
