I look forward to further debates on those matters. The noble Lord is quite right. I hope that your Lordships' House will have further opportunities to discuss the implications of that, because it is a matter of great concern. There are some international companies that seem to feel that they can do what they like, and there is a need for this to be looked at very carefully. I understand the concerns about Governments amassing data. Equally, I refer the noble Lord to Mr Hodder, who wrote to me before Grand Committee, as an example of a business person who has used his card 30 times in going to the European zone and found it very convenient. For that reason, I do not think that we have heard the last word about the use of such cards.
I hope that the Minister considers taking this matter away. Whatever view noble Lords take of what the last Government did and of the nature of the cards and the information, it is rightly important that the public have confidence that the process used is done properly and well, as the noble Lord, Lord Phillips, said. The BBC carried a very interesting story about some of the techniques that will be used to ensure that the information is appropriately destroyed. I welcome that, but it would be helpful-and it is an important matter of public confidence-to have a proper independent scrutiny of this matter, which is why I very much support the noble Lord in his amendment.
