This system, designed in cooperation with the banking industry, is based on chipcard technology and corresponds to the electronic cash system above. The only difference is the possibility of offline authorisation. An authorisation up to a certain limit laid down individually by the issuing bank is stored on the bank card’s chip. This amount decreases with each payment and, as long as the remaining amount is sufficient, transactions are authorised offline. In order to pay, the customers must enter their PIN, which is validated on the chip. Online authorisation will only take place if the amount remaining on the chip. | Global Economic Prospects Volume 4 January 2012 THE WORLD BANK 2012 The International Bank for Reconstruction and Development The World Bank 1818 H Street NW Washington DC 20433 Telephone 202-473-1000 Internet E-mail feedback@ All rights reserved 1 2 3 4 13 12 11 10 This volume is a product of the staff of the International Bank for Reconstruction and Development The World Bank.
