Debit cards have now surpassed cash as the most popular payment method in Switzerland.

According to a Swiss National Bank (SNB) survey released this week, 35% of consumer transactions in stores were paid with debit cards last year, while cash accounted for 30%.

In comparison, in 2017, debit cards made up 21% of the total and cash 70%. Additionally, 18% of transactions were completed using mobile payment apps, and 14% via credit cards, Fortune reports.

Cash remains a highly emotional topic in Switzerland, where the average person holds the equivalent of $10,481 in bills and coins. This makes Switzerland the second-largest holder of cash among all economies tracked by the Bank for International Settlements.

In recent years, signs of declining cash usage have become increasingly evident. The Swiss National Bank stated in October that public transport operators plan to reduce cash transactions, while payment apps, particularly the widely used domestic app Twint, are now more commonly accepted by businesses than debit or credit cards.

Despite this shift, the Swiss government announced last year that it would back a popular initiative aimed at enshrining the right to use cash in the constitution. Unless the proponents of the right-wing group withdraw their proposal, a vote on the matter is expected to take place in the coming years.

The SNB insists that it remains neutral regarding the payment methods citizens choose to use.

However, the central bank, government, and private sector have formed an expert group to address any potential issues with the supply of physical money. Publicly, President Martin Schlegel has reminded citizens that the availability of bills and coins is also influenced by how widely they are used.

“It’s about preventing a vicious circle,” he said last year when the central bank announced plans for a new banknote series. “If the population wants to keep the current availability of cash, then it has to keep using cash.”
