Abstract: To enable the payment of charges, for example those for mobile telephones, with cash there is provided an automated terminal for receiving payments including an input for currency notes, an acceptor for such currency notes and an input for information on an account for charges to which payment is required together with a control arrangement to record said account information and the value of acceptable currency notes fed in, to relate said information to said value as payment to said account and to hold said related information and value and acceptable currency notes available for retrieval.
