I read somewhere that they are moving away from retinal scans and concentrating more on iris scans. They say that it is just as accurate, and less intrusive.

In my opinion, any laser pointed at my eye is a no go.

PS// I think that you might be referring to Ronnie Biggs, who was one of the great train robbers. He left Rio some time ago, and went home a frailing old man (in his late 70's I think), for the reason that he wanted a "pint and a curry". Upon his arrival in the UK, they whacked his arse straight in jail.
