Payments are a big business. According to the Boston Consulting Group, payments generated $1.1 trillion in revenue in 2015, representing 29% of global banking revenues. By 2025, they are projected to reach nearly $2 trillion. Payment cards are the most important and the fastest growing payment instrument. According to the World Payments Report, debit cards accounted for 45.7% of electronic transactions globally in 2014 and grew by 12.8%.

Most of the research focusing on the cost of payments looks at the real, visible and tangible costs and compares them to the cost of cash. There are, however, more costs associated with payments than those direct costs. In the Hidden Costs of Card Payments, Diederik Bruggink and Guillaume Lepecq analyse and, when possible, quantify these costs. They include costs related to:

  • Card Fraud: according to the , card fraud totalled $21.84 billion globally in 2015, a 20.6% annual increase. In the UK alone, over 1 million incidents of financial fraud occurred in the first six months of 2016, according to figures released by  UK (FFA UK), a 53% increase over 2015.

  • Data breaches are more and more common. In the majority of cases they involve theft of credit card details. According to the  Index, over 4.8 billion personal records have been exposed since 2013. The number of breaches grew by 15% in the first six months of 2016.
  • Regulatory Compliance: regulators have imposed all kinds of measures upon the payments industry that can be grouped under the header of compliance, and that have been introduced to make life of criminals and terrorists more difficult: CDD, KYC, FATF, AML… All this comes at a price. .
  • Failed transactions: as a result of the growing complexity of the payments ecosystem, more and more transactions are declined. Some are fraudulent but some perfectly genuine transactions are also blocked. estimates the online shopping cart abandonment rate has reached 68.81%. Almost half of the time, this is due to issues with the payment process.
  • Outages and breakdowns: electronic payments rely on multiple parties and infrastructures and failure of one element in the whole transaction chain can block the ability for merchants to accept card payments.
