Banking Law HELP please:Plastic Cards and Electronic Fund Transfers

Hi, I have made some seminar notes for the following questions but am REALLY confused by the topic so if someone can please give me some help/answers I'd greatly appreciate it! Many thanks:

1. To what extent does the Consumer Credit Act 1974 provide protection to transactions using credit cards as a method of payment?

2. What liabilities are banks likely to incur in the wake of the increased automation of banking services? And what steps might they consider taking to ensure greater protection of their customers in this electronic environment?

3. Read OFT v Lloyds TSM Bank [2006] 2 All ER 821, [2007] UKHL 48. What were the issues raised in the case? How were these dealt with by the respective appellate courts? Do you think the judgement was a sensible one?

It's question 2 and 3 I needed more help with, but any advice on any of these questions would be great! Thanks again
