Today, our central bank, De Nederlandsche Bank (DNB) released survey results on Dutch payments in 2010. It showed that in 2010 consumers in the Netherlands made 4.4 billion cash payments at checkouts (shops, cafés and restaurants, petrol stations and at markets) and some 672 million between persons. So this creates an interesting benchmark for anyone doing studies on payments. If you wish to estimate the number of p2p payments in a country, just take about 16 % of the total cash transactions (but remain aware of cultural differences though...).
The study (only available in Dutch: here) also reveals that most Dutch consumers pay with the payment product that they prefer. So it appears as if everyone in the Netherlands is quite happy with the way we pay. Yet we should note that the scope of the study was limited to the classical payment products. Consumers weren't asked about their preference for strippenkaart, the payment means for public transport:
I would bet that when asked, many would prefer to continue using the strippenkaart over the OV-chipcard with its cumbersome operational flaws and failures. But as of today consumers have no choice, because the strippenkaart has been taken out of circulation. Paper tickets are now only available in trains but the National Railways are planning to scrap these at the end of 2012.
