Abstract:
A method of upgrading a self-service terminal (SST), such as an ATM. An SST is first identified which has (1) a screen for displaying withdrawal options usable by a customer and (2) a touch input mechanism for receiving user commands. Then the SST is modified so that it can receive user commands from a wireless telephone. The modifications may include retro-fitting the SST with a transceiver adapted to receive signals directly from a wireless telephone. Alternately, or additionally, the modifying step may include retrofitting the SST and/or a network system host with a program for enabling the SST to receive a transaction from a remote source.

Description:
The present invention relates to improvements in or relating to a self-service terminal (SST). In particular, the invention relates to a method of modifying an SST, and a method of operating an SST; and more particularly to SSTs in the form of automated teller machines (ATMs). 
   ATMs are widely used for dispensing cash. Conventional ATMs provide a user interface that includes a plurality of user interface elements, such as a display and an encrypting keypad, located within a molded fascia. 
   There are a number of different ATM manufacturers, and each manufacturer produces a different style of ATM. In addition, each manufacturer generally has a range of ATM styles, depending on the level of functionality provided by the ATM. This gives rise to a plethora of different types of user interfaces. Users of an ATM may have to spend time familiarizing themselves with the layout of the ATM before they feel confident enough to use the ATM. 
   As ATMs are public access terminals, typically located in public areas, they involve some degree of security risk. For example, there is the possibility of fraud by a third party observing a user&#39;s PIN as it is entered. There is also the possibility of a third party viewing the balance in a user&#39;s account if this balance is presented on the ATMs display. 
   Environmental factors are also an issue in the use of such ATMs. For example, in inclement weather, it can be an annoyance to input information to a touch input mechanism, such as a touch screen or keypad, at a drive-up ATM. Some users also have an aversion to coming into contact with a cold, soiled, or germ laden touch input mechanism. 
   SUMMARY OF THE INVENTION 
   It is among the objects of an embodiment of the invention to obviate or mitigate one or more of the above disadvantages or other disadvantages associated with conventional ATMs. 
   According to a first aspect of the present invention there is provided a method comprising: identifying an ATM having a display for displaying options for withdrawing cash and a touch input mechanism for receiving user commands; and modifying the ATM to enable it to receive from a wireless user interface, such as a wireless telephone, user commands for dispensing cash. 
   By virtue of this aspect of the invention, an ATM may be modified so that a user can withdraw cash using a wireless telephone, such as a cellular telephone. Thus, a user is able to use the user interface associated with his/her telephone rather than the user interface provided by the ATM. This enables a user to use the same user interface (that of his/her telephone) regardless of the make or style of ATM that they are using. By allowing a user to use his/her wireless telephone, privacy is improved because a third party will have more difficulty in viewing information presented on the telephone&#39;s display than on the ATM&#39;s display. Furthermore, environmental issues can be greatly obviated by allowing a user to bypass, in whole or in part, the existing touch input mechanism. 
   It will be appreciated that the term “wireless telephone” is used herein to include any wireless communication device for facilitating telephone conversations, and is not restricted to a conventional cellular telephone. 
   The modifying step may include retrofitting the ATM with a transceiver adapted to receive signals directly from a wireless telephone. This has the advantage that an existing ATM may be upgraded using a simple, low cost transceiver to allow a user to use a wireless telephone to execute a transaction. 
   Alternatively, the modifying step may include retrofitting the ATM with a remote-transaction program for enabling the ATM to receive a transaction from a remote source. The remote source may be an authorization facility for authorizing transactions, a call center having a secure connection with the ATM, or such like. In operation, a user may dial an authorization facility using a wireless telephone and enter transaction details directly thereto. The authorization facility may then authorize the transaction and transmit the authorized transaction to the ATM. The remote-transaction program enables the ATM to receive the authorized transaction, and the authorized transaction is then executed by the ATM and valuable media (such as banknotes) are dispensed to the user. 
   The advantage of retrofitting an ATM with a remote-transaction program is that the only local modification required for the ATM is a software upgrade (the remote-transaction program): a hardware upgrade is not required. The software modification may be implemented remotely (by uploading or downloading) so that no on-site visit is required. The remote-transaction program may update or replace an existing program resident on the ATM. 
   Where a transceiver is used, the transceiver may be further adapted to transmit signals directly to the wireless telephone so that a user may communicate directly with the ATM via the transceiver and a wireless telephone. 
   The transceiver may be operable in two modes: in one mode the transmitted and received signals may implement a local wireless communication, such as Bluetooth (trade mark); whereas in another mode the transceiver may implement wireless telephony to transmit and receive signals, for example, via a cellular network. 
   In embodiments where the transceiver implements local wireless communication, the method may include the step of retrofitting the ATM with a port for communicating with the transceiver so that a user can align his/her wireless telephone with the port on the ATM. The port may be an IrDA (Infra-red Data Association) compatible port. In other embodiments, the transceiver may not require any external ATM port to implement local wireless communication. 
   In one embodiment, the ATM is connected to a transaction host via a network for communication therebetween, and the modifying step includes providing a connection between the host and the wireless telephone. The connection may be provided by the transceiver implementing wireless telephony to communicate with the host. Alternatively, the connection may be implemented through a land line having a secure connection to an ATM controller, so that the ATM controller can communicate information between the transceiver and the host. 
   In one form, the ATM is connected to a transaction host via a network for communication therebetween, and the modifying step includes: retrofitting the ATM with a transceiver adapted to receive signals directly from a wireless telephone; and providing a connection between the host and the wireless telephone. 
   According to a second aspect of the invention there is provided a method comprising: identifying an ATM having a display for displaying options for withdrawing cash and a touch input mechanism for receiving user commands; and modifying the ATM to enable it to receive from a wireless telephone user commands for dispensing cash without the use of the touch input mechanism. 
   According to a third aspect of the invention there is provided an ATM comprising: a touch input mechanism for receiving user commands; and a transceiver for receiving user commands from a wireless telephone; wherein the ATM is adapted to receive user commands for dispensing cash from each of the touch input mechanism, the wireless telephone, and both. 
   According to a fourth aspect of the invention there is provided a method of operating an ATM having a touch input mechanism for receiving user commands, the method comprising the step of dispensing cash from the ATM in response to user commands from a wireless telephone. 
   The user commands may be communicated from the wireless telephone using wireless telephony. Alternatively, the user commands may be communicated from the wireless telephone using a local wireless communication technique. 
   In one form, the dispensing step occurs without the receipt of user commands from the touch input mechanism. 
   According to a fifth aspect of the invention there is provided a method of operating an ATM having a touch input mechanism for receiving user commands comprising: placing a call from a wireless telephone to the ATM over a wide area communications network; and transmitting information from the wireless telephone to the ATM using both the wireless telephone and the touch input mechanism. 
   In one form, the method further comprises the steps of: dispensing cash from the ATM; and charging a service fee for dispensing the cash to the account of the owner of the telephone. 
   According to a sixth aspect of the invention there is provided a method comprising the steps of: identifying an SST having a display for displaying user options and a touch input mechanism for receiving user commands; and modifying the SST so that it receives user commands from a wireless telephone. 
   The commands may be received directly from a wireless telephone. Alternatively, the commands may be received indirectly, for example, via a call center. Where the commands are received indirectly, the commands received may be in the form of an entire transaction for execution by the terminal. 
   By virtue of this aspect of the invention a method of retrofitting existing SSTs is provided, thereby enabling existing SSTs to be upgraded for access by a wireless telephone retained by a user. This ensures that the user does not need to use a display or a keypad provided by the SST. The cellular telephone may be a conventional cellular telephone. 
   According to a seventh aspect of the invention there is provided a transceiver for installing in an SST during a retrofit operation of the SST, where the transceiver is operable to conduct wireless communication with a user of the SST, and the transceiver is adapted to convey transactions to the SST, so that when the transceiver is installed in an SST a user can execute a transaction on the SST using a wireless communication device. 
   The wireless communication may be implemented by a local wireless technology, such as Bluetooth (trade mark), an IrDA-compliant protocol, or such like. This has the advantage that the user must be located in the vicinity of the transceiver (and therefore in the vicinity of the terminal) to operate the terminal. 
   Alternatively or additionally, the transceiver may be accessible using wireless telephony. If the transceiver is accessible using wireless telephony, then prior to dispensing cash the ATM may request the user to press a certain key on the ATM&#39;s keypad or display to ensure that the user is located at the ATM that is to dispense the cash. If the key is not pressed then the transaction may be aborted and the user requested to ensure that they are located at the correct ATM. 
   Each SST may be provided with a unique identifier so that a user can enter this unique identifier to confirm that the user is at the terminal that is to dispense valuable media. 
   The SST may be an ATM, or a kiosk for dispensing valuable (non-cash) media, such as tickets, passes, or such like. 
   The transceiver may be located within a cash dispensing mechanism, or outside the cash dispensing mechanism but within the SST. 
   In one form, the wireless connection is a telephony connection. 
   According to an eighth aspect of the present invention there is provided a self-service terminal having been retrofitted to allow the terminal to execute transactions entered using a wireless telephone. 
   According to a ninth aspect of the present invention there is provided a self-service terminal having been retrofitted to receive a transaction from an authorized source external to the terminal. 
   The terminal may receive an authorized transaction so that the terminal can implement the authorized transaction without requiring any further authorization. 
   According to a tenth aspect of the present invention there is provided a self-service terminal including a program storage device, the device being upgraded to encode a program of instructions for monitoring an external source and for receiving a transaction from an authorized source via the external source. 
   According to an eleventh aspect of the present invention there is provided a method comprising identifying a system which includes a host and a plurality of ATMs interconnected by a network in which each ATM has a screen for displaying options for withdrawing cash and a touch input mechanism for receiving user commands, and modifying the system to enable at least one of the ATMs to receive from a wireless telephone user commands for dispensing cash. 
   In one form the modifying step includes upgrading a program residing on the host, on one or more of the ATMs, or both the host and ATMs. 
   It will now be appreciated that SSTs and networks of SSTs according to the present invention have a number of advantages. As each user carries his/her own user interface it is easier for each user to personalize his/her user interface. In addition, a user is able to use any interface they desire to communicate with a terminal. This means that a disabled person is able to use a user interface that is adapted for their specific disability, for example a blind person is able to use an audio interface, a deaf person is able to use a visual interface, and such like.

   DETAILED DESCRIPTION 
   Referring now to  FIG. 1 , which is a block diagram of a conventional self-service terminal system  10 , the system  10  comprises a conventional host  12  interconnected to a plurality of SSTs  14  (only two,  14   a  and  14   b , are shown) by a secure network  16 . The SSTs  14  are ATMs. As is well known in the art, the host  12  includes an authorization facility  18  and a back-office facility  20 . The ATMs  14  are physically remote from each other, but are shown in proximity in  FIG. 1  for clarity. 
   Reference is now made to  FIG. 2 , which is a perspective view of one of the ATMs  14  of  FIG. 1 . Each ATM  14  has a user interface  22  located within a molded fascia  24 . The user interface  22  comprises a display  26 , an encrypting keypad  28 , a cash dispense slot  30 , a card entry/exit slot  32 , and a receipt slot  34 . 
   Reference is now made to  FIG. 3 , which is a simplified block diagram of the architecture of the terminal of  FIG. 2 . A system bus (or a plurality of system buses)  36  interconnects various modules in an ATM controller  40  to allow mutual intercommunication, as will be described in more detail below. 
   The user interface  22  comprises the following user interface elements (peripheral devices): a card reader  50 , a display  52 , an encrypting keypad module  54 , a printer  56 , and a cash dispenser  58 . 
   The controller  40  comprises modules for driving the user interface elements  50  to  58 , namely: card reader controller  60 , display controller  62 , keypad controller  64 , printer controller  66 , and dispenser controller  68 . These user interface elements ( 50  to  58 ) and associated controllers ( 60  to  68 ) are standard modules that are used in conventional ATMs and will not be described in detail herein. 
   The controller  40  also comprises a BIOS  70  stored in non-volatile memory, a microprocessor  72 , associated main memory  74 , storage space  76  in the form of a magnetic disk drive, and a dedicated network connection  78  for connecting the ATM  14  to the transaction host  12  ( FIG. 1 ) via the network  16 . 
   In use, the main memory  74  is loaded with an ATM operating system kernel  80 , and an ATM application  82  for controlling the operation of the ATM  14 . 
   The ATM  14  of  FIG. 2  may be modified in accordance with an embodiment of the present invention to produce modified ATM  114 , as shown in  FIG. 4 . ATM  14  is modified to produce ATM  114  by: 
   (1) adding a single mode transceiver  92 ; and 
   (2) updating the controller  40  by loading a new ATM application  182 . 
   The changes to the ATM  14  provide a new ATM  114  with a new controller  140  (differing from the previous controller  40  by a new ATM application  182  and the transceiver  92 ). In other respects, ATM  14  and ATM  114  are similar. 
   The single mode transceiver  92  is coupled to the system bus  36 , thereby allowing the transceiver  92  to communicate with the microprocessor  72  (via bus  36 ). The transceiver  92  has a unique telephone number (which is typically printed on the front of the ATM  114 ) and is operable to transmit and receive signals to and from a cellular network and/or a landline connection. 
   The transceiver  92  may also include a text to speech processor, a speech to text processor, and an encryption/decryption facility (which may implement the RSA public key encryption, or the data encryption standard) so that information conveyed to and from the transceiver  92  can be encrypted for security purposes. 
   The new ATM application  182  allows the microprocessor  72  to send information to and receive information from the transceiver  92 , thereby allowing the transceiver  92  to act as an ATM module. 
   Reference is now made to  FIG. 5 , which is a block diagram of a self-service terminal system  200  in accordance with an embodiment of the present invention. The system  200  is similar to system  10  ( FIG. 1 ) and includes a host  212  interconnected to two ATMs  114  by a network  216 . The host  212  includes an authorization facility  218  and a back-office facility  220 . 
   An authorized user can use a wireless telephone, such as a GSM cellular telephone as shown in  FIG. 6 , to access the system  200 . In this embodiment, the communication device  326  is a standard GSM cellular telephone (such as a NOKIA (trade mark)  7110  telephone) having a microbrowser for accessing Web pages. The phone  326  may use SSL and/or S-HTTP to provide a secure link for transferring highly confidential data, such as a user&#39;s PIN, over an Internet (TCP/IP) connection. Alternatively, cell phone  326  may include a dedicated encryption/decryption facility (not shown) for increasing the security of any transmission. 
   Cell phone  326  has a body  328  housing a keypad  330  for entering numbers and/or letters, a graphics display  332  for displaying graphical information, an antenna  334 , a microphone  336 , a loudspeaker  338 , and an IrDA-compliant port  340 . The cell phone  326  may also include a microbrowser (not shown) for receiving Web pages in WML format. 
   To withdraw cash from an ATM  114 , an authorized user approaches the ATM  114  and dials the telephone number associated with the transceiver  92  (which is typically displayed on the ATM fascia  24 ). The user may have been issued with a password for identification purposes, or the transceiver  92  may use the telephone number or SIM (subscriber identity module) of the user&#39;s telephone to identify the user. 
   The transceiver  92  answers the call from the user and prompts the user to enter his/her password using a speech and/or text-based prompt. The text-based prompt is displayed on display  332  and the speech-based prompt is transmitted to the cell phone&#39;s loudspeaker  338 . 
   Once a customer has entered his/her password (using keypad  330  or microphone  336 ), the telephone  326  encrypts and conveys it to the transceiver  92 . Transceiver  92  performs any speech to text conversion required, decrypts the received password, and then sends an encrypted prompt to the customer&#39;s telephone  326 , which, when decrypted, requests the customer to enter his/her PIN. The entered PIN is then encrypted and conveyed, and the transceiver  92  then requests the user to enter the amount of cash to be withdrawn. 
   Once the transceiver  92  has received the desired amount, the transceiver  92  conveys the transaction information (comprising the user&#39;s password, PIN and the desired amount) to the microprocessor  72  via bus  36 . The microprocessor  72  (which executes the ATM application  182 ) conveys the transaction information to the authorization facility  218  for authorization. 
   On receipt of authorization, the microprocessor  72  informs the transceiver  92  of successful authorization, and the transceiver  92  conveys a message to the user&#39;s phone  326  advising the user that his/her cash is about to be dispensed. The microprocessor  72  instructs dispensing of the authorized amount of cash to the user. 
   Prior to authorizing the transaction, the transceiver  92  may advise the user (via cell phone  326 ) of a transaction charge that will be levied for the transaction, and may request the user to confirm that he/she still wishes to execute the transaction. If within a pre-set time, such as twenty seconds, the user does not confirm that he/she wishes the transaction to be executed then the transaction may be cancelled. If the user does confirm that he/she wishes to proceed with the transaction, then the ATM  114  applies a charge to an account held by the user. This may be a telecommunications account for the cellular telephone, or it may be a bank account. 
   For each transaction, the ATM  114  may credit a user&#39;s telecommunications account with free time, for example, one minute for each dollar that has been withdrawn. 
   In another embodiment, a wireless telephone having an integral identifier (such as a biometrics sensor in the form of a fingerprint sensor) may be used. In such an embodiment, the device may provide a special signal when the user of the device has been identified. This special signal may be used by a transceiver as confirmation of the user&#39;s identity, thereby avoiding the need for the user to enter a PIN. 
   The ATM  14  of  FIG. 2  may be modified in accordance with another embodiment of the present invention to produce modified ATM  214 , as shown in  FIG. 7 , for use in an ATM system  400 , as shown in  FIG. 8 . 
   ATM  14  is modified to produce ATM  214  by: 
   (1) adding an infra-red port  290  to the user interface  22  so that the port  290  protrudes through the existing fascia  24 ; 
   (2) adding a dual mode transceiver  292 ; and 
   (3) updating the controller  40  by loading a new ATM application  282 . 
   These changes to ATM  14  provide a new ATM  214  with a new fascia  222  (differing from the previous fascia  22  by the presence of the port  290 ), and a new controller  240  (differing from the previous controller  40  by a new ATM application  282  and the transceiver  292 ). In other respects, ATM  14  and ATM  214  are similar. 
   The port  290  is an IrDA-compliant module for receiving and transmitting information in infra-red format. 
   The dual mode transceiver  292  is coupled to the system bus  36 , and the infra-red port  290  is coupled to the transceiver  292 ; thereby allowing the transceiver  292  to communicate with the microprocessor  72  (via bus  36 ) and a user (via port  290 ). The transceiver  292  has a unique telephone number (which is typically printed on the front of the ATM  214 ) and is operable to transmit and receive signals to and from a cellular network and/or a landline connection. 
   The transceiver  292  may also include a text to speech processor, a speech to text processor, and an encryption/decryption facility (which may implement the RSA public key encryption, or the data encryption standard) so that information conveyed to and from the transceiver  292  can be encrypted for security purposes. 
   The transceiver  292  can operate in a first mode using a local communication protocol such as Bluetooth (trade mark), or in a second mode using wireless telephony. 
   When wireless telephony is used, the transceiver  292  communicates via a cellular network (not shown) and the ATM  214  operates in the same manner as described with reference to the ATM  114  of  FIG. 4 . 
   An authorized user can use a wireless telephone (such as the GSM cellular telephone shown in  FIG. 6 ), or any other wireless communication device having an IrDA-compliant port (such as a personal digital assistant), to access the ATM  214 . 
   Reference is now made to  FIGS. 6 to 9 . To withdraw cash from ATM  214  using cell phone  326 , a user  402  approaches the ATM  214  and executes a cell phone transaction program (not shown). This transaction program may be resident on the phone  326  or may be downloaded from a Web site using the phone&#39;s microbrowser. The cell phone transaction program provides the user  402  with a user interface for preparing a transaction, and also provides an encryption facility for encrypting the transaction. 
   The user  402  prepares a transaction using this cell phone program and executes the transaction by aligning the telephone&#39;s IrDA port  340  with the ATM&#39;s port  290  and transmitting the prepared transaction, as illustrated by broken line  404  in  FIG. 9 . 
   On receiving the encrypted prepared transaction, the IrDA port  290  conveys the transmission to the processor  72 . The processor  72  decrypts the received transaction and sends the received PIN and transaction request to the host  212  ( FIG. 8 ) for authorization. The processor  72  then conveys a message to the cell phone  326  informing the user  402  that the request is being authorized. 
   On receipt of authorization from the host  212 , the processor  72  instructs the cash dispenser  58  to dispense the requested cash. The dispenser  58  dispenses the cash, and the processor  72  transmits a message to the phone  326  (via ports  290  and  340 ) indicating that the user&#39;s cash has been dispensed. The user  402  then removes the dispensed cash to complete the transaction. 
   If the transaction is not authorized or if the cash cannot be dispensed, then the processor  72  transmits a message to the phone  326  to inform the user  402  that the transaction cannot be executed. This provides the user  402  with feedback relating to the status and progress of the transaction being executed. 
   Reference is now made to  FIGS. 10 and 11 , which show yet another embodiment of the present invention. In  FIG. 10  a system  500  is shown that is similar to system  10  ( FIG. 1 ) and includes a host  512  interconnected to two ATMs  514   a  and  514   b  by a network  516 . The host  512  includes an authorization facility  518 , a back-office facility  520 , and a call center  522 , automated or otherwise. The call center  522  is operable to receive telephone calls directly from a wireless telephone so that a wireless telephone user can telephone the call center  522  to enter a transaction. The call center  522  is capable of receiving telephone calls for either ATM  514 . 
   ATM  514   a  is a modified version of ATM  14   a  ( FIG. 1 ). ATM  514   a  has a new controller  540  (differing from the previous controller  40  by a new ATM application  582  and a new remote-transaction program  524 ). In other respects, ATM  14   a  and ATM  514   a  are similar. In other embodiments the new ATM application  582  and the remote-transaction program  524  may be combined into a single program. 
   In use, the ATM  514  executes the transaction program  524 . The program  524  monitors the network connection  78  to detect an incoming transaction from the host  512 . 
   To use the ATM  514   a , a customer approaches the ATM  514   a  and dials the call center  522  telephone number, which may be printed on the front of the ATM  514   a . The call center  522  provides the user with a menu of transactions to allow the user to enter transaction details. The call center  522  then conveys this entered transaction to the authorization facility  518  to authorize the transaction. 
   When the transaction has been authorized the call center  522  conveys the authorized transaction to the ATM  514   a . The remote-transaction program  524  detects the arrival of the authorized transaction and informs the ATM application  582 . The ATM application  582  then executes the authorized transaction and dispenses any cash that has been requested in the transaction. 
   Reference is now made to  FIG. 12 , which shows yet another embodiment of the present invention. In  FIG. 12  a system  600  is shown and includes a host  612  interconnected to two ATMs  614   a  and  614   b  by a network  616 . The host  612  includes a software program  694 . Each ATM  614  may also include an ATM application (not shown). System  600  may be modified by changing or upgrading the program  694  to enable at least one of the ATMs  614  to receive from a wireless telephone user commands for dispensing cash. Alternatively, the system  600  may be modified by upgrading the ATM application on the ATM(s)  614  to receive from a wireless telephone user commands for dispensing cash. In another variation, both program  694  and the ATM application(s) may be upgraded to receive from a wireless telephone user commands for dispensing cash. 
   Yet another embodiment of the present invention applies to an ATM which is connected to a host through either a private or public network for communication therebetween. In this embodiment, the system is adapted to allow communication to proceed between the user and the ATM through a wireless telephone network. In other words, a call would be placed by the user over his/her wireless telephone network, communication thereby being established with the host and signals transmitted therefrom to the ATM. In this embodiment, modifications may be made to the ATM application residing on the ATM, but no transceiver would be added to the ATM. 
   In another embodiment, a transceiver may be added as shown in  FIG. 4 , and communication may proceed over two paths—the cellular network as described in the preceding paragraph and the transceiver. 
   In an alternative form of operation of any of the embodiments described herein, the user may insert his/her card into a card reader to verify his/her presence at the ATM. Otherwise, communication will proceed through the user&#39;s wireless telephone. 
   Various modifications may be made to the above described embodiment within the scope of the invention, for example, the media dispensed may include stamps, telephone cards, ski passes, or such like. In other embodiments, a single mode transceiver that allows only local wireless communication may be used in the ATM, and a wireless telephony transceiver may be located in a call center remote from the ATM so that only local communication may occur at an ATM. In other embodiments, a user&#39;s account number and PIN (or an encrypted version thereof) may be stored in the user&#39;s SIM and may be transferred by the telephone only after the user has entered a release code, so that the account number and PIN cannot be read or overwritten unless a valid release code has been entered. The ATMs may be connected to the host via a public or a private network. 
   In another variation, the ATM Application may reside on the host and not within the ATM as described above. 
   In yet another variation, in certain circumstance it may be desirable to have the user make limited use of the touch input mechanism prior to dispensing media from the SST. For example, to verify his/her physical presence at the SST, or to enter other information in combination with the use of the wireless telephone.
