The terminals +provide an interface for sending a specified amount (integer number) to a player (who must +have an existing banking account) and for checking the transfers to the account of the user of +the terminal. The history of transactions can be erased completely, and it is recommended to +clean it once the stored data are no longer of any relevance. Otherwise, the transaction history +is preserved indefinitely. + +[ steel ingot, mese crystal, steel ingot ] +[ glass, mese wire, steel ingot ] +[ steel ingot, mese crystal, steel ingot ] + +To complete a wire transfer a player must provide the name of the recipient with an +existing banking account, the desired amount to be transfered, and a description of the +payment (optional, but strongly recommended). +After entering those parameters the terminal checks their validity and if there is no problem, +the player is shown the final confirmation window. If the player confirms the payment, the specified +amount will be transfered immediately. At this point the transaction is final. +If there are errors, a corresponding message is shown in the chat, and the transaction is aborted. + ## Founder This is a fork of gpcf's ATM mod: git://gpcf.eu/atm.git
