Task One Automated Teller Machines1. interpret diagram over page for Input and output devicesThis kind of port is an interactive interface with thotons. Ithink this would be improved good and the ways that I think get out be improved by more security measure on the machines. I think they will mother devices like retina scans, voice activation and thumbprints. Atthe moment the only security is PINS and cards but they can be stolenand I think they will improve the security more.2. The attend to for a customer obtaining specie is called effectprocessing in real age.This kind of processing is called transaction processing. If the cashwithdrawal is required, the customer enters the amount they want fromthe machine. This is because checked against the ease of the accountand if funds be 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 services are available are withdrawal of cash, orderingof statements, requests for new bank checkbooks and obtaining the balanceof the account.AdvantagesDisadvantagesTo the lodgeEmploys fewer peopleHigh level of security neededIt is cheaper than pay 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 effort and backPIN stands for Personal Identification Number, it acts like apassword, and the substance abuser enters it to the ATM keypad to verify that theyare the account holder. The PIN helps to disgrace fraud.The information stored on the magnetic strip is account numbers, bank classification code, system number, c heque digitTask two - Cheque modifyThere are three sets of numbers printed along the bottom of the chequeusing magnetic ink and machines can automatically admit these numbers.MICR stands for magnetized Ink Character Recognition, it works byinputting special ink onto cheques and the ink then is magnetised. Thelimits are that very few characters could be recognised 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 Transaction Processing it
