How technology has transformed your finances: from the abacus to the best tools of 2025

“Innovation distinguishes leaders from followers.” – Steve Jobs, American technology visionary and entrepreneur.

History of financial technology: from currencies to Artificial Intelligence

Since the first merchants drew lines in the sand to count their goods, humanity has sought ways to simplify and optimize money management. Today, with virtual assistants that can remind you to pay a bill or invest automatically while you sleep, the journey of financial technology seems straight out of a science fiction novel. But this journey began thousands of years ago when the tools were as rudimentary as they were brilliant.

1. The first steps: abacuses and coins (6th century B.C.)

Imagine a merchant in ancient Lydia, surrounded by fabrics, spices, and precious stones, trying to close a deal. His hands pass nimbly across an abacus, that magical tool of wood and beads that made calculations quick and precise. On the other side, his client checks a small bag of freshly minted coins, symbolizing trust and progress in a world where barter is still the norm.

The abacus, born in Asia 5,000 years ago, allowed merchants to prosper and laid the foundations for the first financial “calculators”. With the introduction of coins in Lydia around the 6th century BC, a colossal leap was made: transactions became faster, fairer, and, most importantly, accessible to the masses. Global trade was beginning to take shape.

“Early financial advances, such as the abacus and coins, transformed commerce and laid the foundation for financial technology.”

2. Printing and financial education (15th century)

Fast forward to the 15th century, when Gutenberg’s printing press changed the world. Before this invention, knowledge about personal finance was reserved for elites, hidden away in manuscripts inaccessible to most. However, with the advent of the first printed books, concepts such as saving, investing, and planning began to reach the hands of ordinary people.

Think of a family in Renaissance Europe that, for the first time, has access to a small book that teaches them how to save for an uncertain future. This milestone democratized knowledge and started a silent revolution: financial education as a tool for empowerment.

“The printing press democratized financial education, bringing savings and investment concepts closer to ordinary people.”

3. Banks for the common people (19th century)

With the Industrial Revolution, cities began filling with factories, trains, and banks. Until then, banks were the exclusive bastions of the elite. However, savings banks, designed for the working classes, gave millions of people access to financial tools such as bank accounts and loans for the first time.

Imagine a worker depositing his first salary coins in a local savings bank. That simple gesture represented more than money; it was hope, a promise of the future, of being able to plan and dream. This breakthrough changed individual lives and laid the foundation for the modern economy.

“Modern banks empowered the working classes, making savings and financial planning accessible.”

4. The electronic calculator (1970s)

Enter a 1970s kitchen, where a mother is adjusting the family budget. In her hands, a shiny new electronic calculator converts complicated interest formulas into simple numbers. This small device, which came into homes thanks to advances in electronics, marked a crucial change: for the first time, families could manage their finances accurately and quickly.

Until then, financial calculations relied on pencil and paper or the help of experts. With calculators, anyone, regardless of their level of education, could take control of their budget and better plan their future.

“The electronic calculator brought financial accuracy to households, simplifying money management.”

5. The digital revolution: the Internet and online finance (1990s)

As the world entered the digital age, finance also took an impressive leap forward. Online banks allow people to access their accounts from home, make transfers in seconds, and, most revolutionarily, compare prices and services in real time.

For the first time, the relationship with money became genuinely global. A family in New York could pay their children’s tuition fees in London with a single click. The Internet removed barriers and opened up various learning, saving, and investing possibilities with tools such as loan simulators or free online courses.

“The Internet transformed personal finance by making it more accessible and global.”

6. Smartphones and financial apps (2008 onwards)

With smartphones, everyone started carrying a financial office in their pocket. Apps like Mint and Venmo simplified budgeting, made it possible to split bills in seconds, and offered reminders so you wouldn’t forget to pay bills.

The most amazing thing? Anyone could start investing with just a few dollars, something unimaginable decades ago. Apps like Robinhood removed barriers and democratized access to the stock market, while platforms like PayPal connected millions of people to global trading.

“Mobile apps transformed smartphones into essential tools for financial management.”
