Given the advantages of electronic money, you might think that we would move quickly to th

e cashless society in which all payments are made electronically. 1 a true cashless society is probably not around the corner. Indeed, predictions have been 2 for two decades but have not yet come to fruition.

We often hear media reports that an unauthorized hacker has been able to access a computer database and to alter information 15 there. The fact that this is not an 16 occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems and 17 from someone else&39;s accounts. The 18 of this type of fraud is no easy task, and a new field of computer science is developing to 19 security issues. A further concern is that the use of e lectronic means of payment leaves an electronic 20 that contains a large amount of personal data. There are concerns that government, employers, and marketers might be able to access these data, thereby violating our privacy.
