It asked around 1,200 study participants in late October and early November 2010 to carry a payments diary with them for a week and record details of all their payments and cash withdrawals. Details recorded included: the payment method used; the size of the transaction; the merchant category and the payment channel (for example, in person, internet, phone, or mail).
For this purpose, the Secretariat of the Committee is busy with the compilation of an information data bank on the participating central banks; a co-ordinated training programme for central bank officials.
