The statistic comes from the European Central Bank's study on Cash Use by Household in the Euro Area, published in November 2017.
The report presents estimations of the number and value of cash transactions in all 19 euro area countries in 2016, based on survey result as well as figures on main payments by demographic.
According to the findings from the European Central Bank's report, cash was used for 87% of point-of-sale payments in Spain in terms of number of transactions (ECB, 2017).
Excerpt from ECB Diary report
In 2016 euro area consumers made 1.6 payments per day on average, which equals nearly 11 payments per week. They used cash more frequently than other payment instruments, making on average 1.2 cash payments per day, i.e. almost nine per week. The second most frequently used payment methods were payment cards, which consumers used on average 0.3 times per day, i.e. 2.1 times per week.
However, these are euro area averages, since payment behavior varied from country to country. Italy, Spain and Greece were the countries where consumers made the highest number of cash payments per day, with 1.7 transactions per day, i.e. nearly 12 per week.
On the other hand, consumers in the Netherlands, Luxembourg, Finland and Estonia made the highest number of card payments per person per day, with 0.8, 0.6 and 0.5 payments per day, respectively. This is equal to 5.3, 4.1 and 3.8 payments per week, respectively.
