Task One Automated Teller Machines1. See plot over page for Input and output devicesThis kind of interface is an synergistic interface with buttons. Ithink this would be improved considerably and the slipway that I thinkwill be improved by more than security on the machines. I think they willhave devices similar(p) retina s green goddesss, voice activation and thumbprints. Atthe moment the only security is PINS and card game but they thunder mug be stolenand I think they will improve the security more.2. The process for a customer obtaining cash is called transactionprocess in real prison term.This kind of processing is called transaction processing. If the cash climb-down is required, the customer enters the amount they want fromthe machine. This is consequently checked against the balance of the method of accountingand if funds are obtainable of the account, the machine dispensesmoney. Also at the same the amount from the account is subtracted fromthe balance on the cus tomers record on the assert computer. When itsfinished the card releases pole the card to the customer.IMAGEOther services are available are withdrawal of cash, orderingof statements, requests for new chequebooks and obtaining the balanceof the account.AdvantagesDisadvantagesTo the BankEmploys few peopleHigh level of security neededIt is cheaper than paying caterHackers could break into the machinesLess need to build banks and money could be apply 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 automatic tellerThey 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 standard pressure keypad to verify that theyare the account holder. The PIN helps to reduce fraud.The training stored on the magnetic strip is account numbers, banksort code, brass number, cheque digitTask two - Cheque clearing in that location are three sets of numbers printed along the bottom of the cheque exploitation magnetic ink and machines can automatically read these numbers.MICR stands for Magnetic sign Character Recognition, it works byinputting special ink onto cheques and the ink then is magnetised. Thelimits are that very few characters could be prize but it can beread quite fast. The special ink then is recognised by using a processcalled MICR. Its used on cheques because it has risque security and ifthe special has been tampered on, the computer can still read the infoon the special magnetised ink.The cheque clearing process is called feat Processing it
