delegate One Automated Teller Machines1. See diagram over page for Input and output devicesThis salmagundi of interface is an synergistic interface with buttons. Ithink this would be improved considerably and the ways that I thinkwill be improved by more protective covering on the political machines. I think they willhave devices like retina s contributes, voice activation and thumbprints. Atthe moment the only security is PINS and cards but they do-nothing be stolenand I think they will improve the security more.2. The process for a customer obtaining cash is called transactionprocessing in real time.This kind of processing is called transaction processing. If the cashwithdrawal is required, the customer enters the amount they want fromthe machine. This is then checked against the balance of the accountand if funds are available of the account, the machine dispensesmoney. Also at the same the amount from the account is subtracted fromthe balance on the customers record on the bank computer. When itsfinished the card releases back the card to the customer.IMAGEOther work are available are withdrawal of cash, orderingof statements, requests for new chequebooks and obtaining the balanceof the account.AdvantagesDisadvantagesTo the lodgeEmploys fewer peopleHigh level of security neededIt is cheaper than paid staffHackers could break into the machinesLess need to build banks and money could be used elsewhereEmployees loose their jobs.To the customerIt is fast.Credit cards could be stolenIt can be accessed anytimeThe magnetic strips can be damaged by the ATMThey can get it anywhereThe card has to be replaced from time to time3. Bank cards, credit and debit cardsDiagram front and backPIN stands for Personal Identification Number, it acts like apassword, and the user enters it to the ATM keypad to ramble that theyare the account holder. The PIN helps to reduce fraud.The information stored on the magnetic strip is account numbers, banksort code, system number, cheque digitTask two - Cheque clearingThere are three sets of numbers printed along the bottom of the chequeusing magnetic ink and machines can mechanically read these numbers.MICR stands for Magnetic Ink Character Recognition, it works byinputting special ink onto cheques and the ink then is magnetised. Thelimits are that very few characters could be recognise but it can beread quite fast. The special ink then is recognised by using a processcalled MICR. Its used on cheques because it has high security and ifthe special has been tampered on, the computer can still read the dataon the special magnetised ink.The cheque clearing process is called dealings Processing it
