Cover up your Pin's guy's - be it at cash m/c's, Sainsbo's, the dodgy Petrol Station with cameras in the a/c unit (located near the LL roundabout!). In this day and age its a bit like having unprotected s3x! I have developed a one-handed technique where I am able to cover all of the digits on the keypad with my hand and slide my thumb underneath to punch in the relevant numbers - took a bit of practice (sad I know), but keeps me protected!
