A cashless payments company is offering a monthly payments system that it claims "revolutionises the charity industry".
Six Payment Services' system enables donors to make monthly or one-off payments on their credit cards without having to give bank details.
World Vision Switzerland has become the company's first not-for-profit organisation to sign up for it.
A donor gives an initial set amount using their credit card via a handheld point-of-sale device, with the option to make a contactless transaction. The donor’s card is then charged with the same amount each month as a recurring payment until he or she chooses to amend or terminate the subscription.
Six Payment Services hopes donors will soon be able to pay via mobile phones and tablets.
"The effortlessness pays off in many ways," said Dr Adrian Sargeant, executive director of the Philanthropy Centre. "More than 70 per cent of people who make one-off payments rarely come back and make new gifts.
"Various studies suggest that revenue from these sustaining supporters is 600 to 800 per cent higher than from donors who contribute annually.
"Donors who give through a monthly giving programme also tend to remain loyal to the charity for several years."
Bernhard Metzger, chief executive of World Vision Switzerland, said the system offered donors "a modern and convenient payment solution".
He added: "This helps us to optimise our processes and to reduce administrative effort."
Roger Niederer, head of merchant services at Six Payment Services, said: "We have seen an increase in interest from charities looking to broaden the strategy and power of their campaigns to maximise donations in order to continue their important work."
