er identifies him or herself by inserting a plastic card with a magnetic stripe that contains his or her account number. The
custom
er then verifies his or her identity by entering a passcode (PIN) of four or more digits. If the number is
engineering
entered incorrectly several times in a row (usually three) , most
atm
will retain the card as a
security
precaution to prevent an unauthorised user from discovering the PIN by guesswork (these cards are often destroyed if the
atm
owner is not the card issuing bank as non
custom
er's identities
engineering
cannot be checked) . In some cases, the
custom
er's PIN may be changed using the machine. Some
atm
use smartcards to store
custom
er data.Early
atm
security
focused on making the
atm
invulnerable to physical attack; they were effectively safes with dispenser mechanisms. A number of attacks on
atm
resulted, with
engineering
thieves attempting to steal entire
atm
by ram-raiding.Modern
atm
physical
security
, per other modern money-handling
security
, concentrates on denying the use of the money inside the machine to a thief, by means of techniques such as dye markers and smoke canisters. This change in emphasis has meant that
atm
are
engineering
now frequently found free-standing in places like shops, rather than mounted into walls. Another trend in
atm
security
leverages the existing
security
of a retail establishment. In this scenario, the fortified cash dispenser is replaced with nothing more than a paper-tape printer. The
custom
er requests a withdrawal from the machine,

which dispenses no money, but merely prints a receipt. The
custom
er then takes this receipt to a nearby sales clerk, who then exchanges it for cash from the till. Many books on
