the city council passed an ATM security bill as well. In China and elsewhere, many efforts to promote security have been made. On-premises ATMs are often located inside the bank's lobby, which may be accessible 24 hours a day. These lobbies have extensive security camera coverage, a courtesy telephone for consulting with the bank staff, and a security guard on the premises. Bank lobbies that are not guarded 24 hours a day may also have secure doors that can only be opened from outside by swiping the bank card against a wall-mounted scanner, allowing the bank to identify which card enters the building. Most ATMs will also display on-screen safety warnings and may also be fitted with convex mirrors above the display allowing the user to see what is happening behind them. As of 2013, the only claim available about the extent of ATM-connected homicides is that they range from 500 to 1,000 per year in the US, covering only cases where the victim had an ATM card and the card was used by the killer after the known time of death. Jackpotting The term is used to describe one method criminals utilize to steal money from an ATM. The thieves gain physical access through a small hole drilled in the machine. They disconnect the existing hard drive and connect an external drive using an industrial endoscope. They then depress an internal button that reboots the device so that it is now under the control of the external drive. They can then have the ATM dispense all of its cash. Encryption In recent years, many ATMs also encrypt the hard disk. This means that actually creating the software for jackpotting is more difficult, and provides more security for the ATM. Uses ATMs were originally developed as cash dispensers, and have evolved to provide many other bank-related functions: Paying routine bills, fees, and taxes (utilities, phone bills, social security, legal fees, income taxes, etc.) Printing or ordering bank statements Updating passbooks Cash advances Cheque Processing Module Paying (in full or partially) the credit balance on a card linked to a specific current account. Transferring money between linked accounts (such as transferring between accounts) Deposit currency recognition, acceptance, and recycling In some countries, especially those which benefit from a fully integrated cross-bank network (e.g.: Multibanco in Portugal), ATMs include many functions that are not directly related to the management of one's own
