I remember the first ATMs I used back in the late 1970s. They were IBM machines with a red LED display, single-line, in a fairly heavily armoured, tiltable (to take into account people's different heights) slot.

These days we have big, full-colour LCD displays, without armouring. In Lincolnshire UK, where I live thieves just pull the whole ATM out of wall with a (stolen) JCB digger and take it away to be cut open at their leisure. That is if they can find one, of course. For both thief and bank customer ATMs are becoming increasingly rare - though not as rare perhaps as brick-and-mortar bank branches.
