Retail non-cash payments are growing fast globally, and should continue to do
so, even in markets where non-cash means of payment are already quite popular,
according to data gathered in researching the World Payments Report 2008.

– with the number of transactions conducted via cards growing a sustained 16%
per year in 2001-06.
