Debit card transaction systems may include J-Debit, VISADebit and Debit Master. Prepaid card transaction systems may include Eddy, Suica, PASMO, nanaco, and WAON. The aforementioned systems and devices are exemplary and mobile terminal 10 may comprise ones for other electronic payment systems or devices. Also, mobile terminal 10 may be an electronic computer terminal or an IC card that incorporates a built-in non-contact IC chip such as for example FeliCa (Registered Mark), MIFARE (Registered Mark) or NFC (Near Field Communication) chips.
Mobile terminal 10 comprises memory means 34 such as a memory card or flash memory in cellular phone for storing code information that includes an account number of a holder's debit or prepaid card, PIN (Personal Identification Number) and/or ID (Identification) number, entry means 31 such as a numerical keypad or keyboard in cellular phone for inputting an amount of a transaction fee signal such as gaming fees into memory means 34, a CPU 35 electrically connected to all means for preparing a remotely operable signal inclusive of the code information stored from memory means 34, transmission means 32 for transmitting remotely operable signal from CPU 35 to communications device 5, reception means 33 for receiving a deal signal from communications device 5 when communications device 5 transmits to mobile terminal 10 the deal signal produced by communications device 5, and battery means (not shown) for supplying electric power to each means to perform reading, writing, transmitting and receiving functions in mobile terminal 10. Memory means 34 does not need to store the code information for enhancement in security if any code signals may be produced by entry means 31 and transmitted outside through transmission means 32. A single convertible transceiver means may be used for transmission and reception means 32, 33. CPU 35 may prepare remotely operable signal that contains an transaction fee signal and a code signal inclusive of account number of debit or prepaid card, PIN (Personal Identification Number) and/or ID (Identification) number.
There are a variety of automated machines for receiving transaction fee signal from communications device 5 may include automated teller machines, vending machines, money exchangers or other money-operated equipment or apparatus. The present invention adopts a gaming machine 1 as an example of automated machines, however, it would be apparent to ordinary skill in the art that the electronic payment system of the present invention can also apply to drive other automated machines in a similar way.
Communications device 5 and automatic payment device 6 are electrically linked to each other through wired, wireless or intranet connection, Internet or combination thereof. Payment device 6 and financial database 7 such as banking systems are linked to each other through wired, wireless, intranet connection, Internet or combination thereof. In embodiments of the present invention, communications device 5 may be disposed within, outside of or adjacent to gaming machine 1 so far as users may operate mobile terminal 10 to access communications device 5 in the vicinity of or at a location not too far away from gaming machine 1. Both communications device 5 and payment device 6 may be disposed within or outside of gaming machine 1 for any spatial reason, so far as users may easily access gaming machine 1 and operate communications device 5. For a similar reason, one of communications device 5 and payment device 6 may be disposed within or outside of gaming machine 1 so far as they may be electrically linked each other.
Communications device 5 comprises a signal processor 5b connected to automated machine 1 for retrieving and producing an account number that identifies a holder of the account at financial database 7 and if necessary holder's PIN and/or ID numbers and monetary signals from remotely operable signal received from mobile terminal 10, and a communications interface 5a for intervening telecommunication between mobile terminal 10 and signal processor 5b. 
FIG. 2 illustrates a typical example of the automated machine applied to a schematically depicted gaming machine 1. Gaming machine 1 comprises a bill acceptor 4, a drive device 3 connected to communications device 5 and to gaming hardware 2 and a printer 11 for recording game information on a recording medium. Bill acceptor 4 validates a bill inserted from outside to produce a bill monetary signal to drive device 3 as a monetary signal of transaction fee when bill acceptor 4 decides that the inserted bill is genuine. Drive device 3 generates to gaming hardware 2 drive signals of the amount equivalent to a value of received monetary signal to present games when receiving each monetary signal from bill acceptor 4. Printer 11 prints on recording medium data of game information, money amount to be refunded and management codes to issue the recording medium as a coupon.
Bill acceptor 4 comprises an inlet sensor 21 for producing a detection signal when a bill is inserted into bill acceptor 4, a bill sensor 22 for producing a characteristic signal inclusive of an optical or magnetic signal when a bill is moved along bill sensor 22, a conveyor (not shown) for transporting a bill along a passageway 23 in bill acceptor 4 and a control device 8 for receiving detection signal from inlet sensor 21 and characteristic signal from bill sensor 22 to produce drive signals to conveyor when control device 8 considers the bill as being genuine. Specifically, control device 8 may verify whether or not the bill is genuine and what kind of denomination the bill has, and when it decides that the bill is genuine, control device 8 generates a denomination signal of the bill as a monetary signal to drive device 3. On the other hand, control device 8 also receives from communications device 5 monetary signal sent from mobile terminal 10, and so, transmits to drive device 3 either of monetary signals that bill acceptor 4 produces and relays from communications device 5. Control device 8 is electrically connected to a converter 5c of communications device 5 for converting denomination signal from signal processor 5b into a serial denomination signal and transmitting serial denomination signal to control device 8 of bill acceptor 4. Control device 8 has a memory area for storing a specific code identifying gaming machine 1 and also storing both monetary signals that bill acceptor 4 produces and relays from communications device 5. Otherwise, the present invention also contemplates that bill acceptor 4 may validate valuable coupon tickets, scrip, tender, tokens or substitutes of bills.
Bill acceptor 4 validates a bill inserted from outside to produce a monetary signal of the bill to drive device 3 when bill acceptor 4 decides that the inserted bill is genuine. Bill acceptor 4 also receives a monetary signal contained in remotely operable signal from signal processor 5b through converter 5c of communications device 5, and forwards monetary signal to drive device 3. Then, drive device 3 receives either of monetary signals from bill acceptor 4 to generate to gaming hardware 2 drive signals of the amount equivalent to a value of either received monetary signal to allow gaming hardware 2 to conduct a game. Each of monetary signals may indicate a money amount corresponding to one or more of denominations of bills optically or magnetically readable by bill acceptor 4. In other words, money amount to be transmitted may be selected from amounts in denominations of bills readable by bill acceptor 4. By way of example, when bill acceptor 4 can selectively validate bills of five kinds, i.e. one-dollar, five-dollar, ten-dollar, twenty-dollar or one hundred-dollar bills, it would be preferable to send signals of the amount selected from one-dollar, five-dollar, ten-dollar, twenty-dollar or one hundred-dollar bill from mobile terminal 10 to communications device 5.
Drive device 3 may generate to gaming hardware 2 drive signals of the amount equivalent to a value of the received monetary signal when receiving monetary signal through bill acceptor 4. Otherwise, communications device 5 may forward monetary signal of transaction fee directly to drive device 3 without bill acceptor 4 so that drive device 3 may produce to gaming hardware 2 drive signals of the amount equivalent to the amount of transaction fee to drive gaming hardware 2 by drive signals from drive device 3. This allows users to select either cash or cashless electronic payment for gaming in amusement halls or casinos.
Bill acceptor 4 also comprises a stacker 9 for accommodating bills considered genuine by control device 8, and a memory device 12 electrically connected to control device 8 and attached to stacker 9 for storing monetary or denomination signals, account number signals, PIN and ID number signals and specific code signal identifying gaming machine 1 forwarded from control device 8. Control device 8 distinctively stores in the memory area both monetary signals produced by control device 8 and transmitted from communications device 5. Memory device 12 distinctively stores both monetary signals transmitted from both control device 8 and communications device 5, account number signals, PIN and ID number signals and specific code signal identifying gaming machine 1 all forwarded from control device 8. Bill acceptor 4 is removably attached to gaming machine 1 and also stacker 9 is removably attached to bill acceptor 4 to easily take out and collect bills accumulated in stacker 9. Accordingly, when bills in stacker 9 are to be collected, bill acceptor 4 is detached from gaming machine 1 and then stacker 9 is removed from bill acceptor 4.
In operation, when mobile terminal 10 moves closer to communications device 5, it emits radio signal inclusive of the account number signal of financial database 7 identifying a holder of the account and transaction fee signal to be paid for operation of gaming machine 1. Then, communications device 5 receives radio signal to retrieve holder's account number in radio signal and also receive a monetary signal indicative of transaction fee that may be involved in radio signal. Alternatively, communications device 5 may be connected to an entry device 25 for inputting a monetary signal of a transaction fee for gaming machine 1 to transmit monetary signal from entry device 25 to communications device 5. Then, payment device 6 may receive monetary signal from entry device 25 through communications device 5 simultaneously with, before or after receiving radio signal from mobile terminal 10. Then, just like through an on-line debit or prepaid card system, payment device 6 may withdraw the amount of transaction fee from holder's account at financial database 7 when the amount of transaction fee is within a deposit balance of the account. Then, payment device 6 produces an authorization signal to communications device 5 that then sends the monetary signal to gaming machine 1 to drive it.
In another embodiment of the present invention, remotely operable signal may include PIN and/or ID numbers to more strictly identify the holder in addition to the holder's account number of mobile terminal 10 to increase security against unauthorized access to the holder's account. When mobile terminal 10 emits radio signal inclusive of account number and PIN and/or ID number, communications device 5 may receive radio signal, retrieve account number and PIN and/or ID numbers from radio signal and withdraw the amount of transaction fee from holder's account at financial database 7 when PIN and/or ID numbers correspond to one or ones of pass-codes or secret numbers at financial database 7. In lieu of PIN and/or ID number included in radio signal, entry device 25 may be used to produce PIN and/or ID number signals from entry device 25 connected to communications device 5 to feed them to payment device 6 through communications device 5 so that payment device 6 may withdraw the amount of transaction fee from holder's account at financial database 7 when PIN and/or ID numbers correspond to one or ones of pass-codes or secret numbers at financial database 7.
In a further embodiment of the instant invention, communications device 5 may be connected to a visual and/or acoustic display device 20. When communications device 5 receives authorization signal from payment device 6, it produces and transmits a deal signal to mobile terminal 10 and/or to display device 20 to exhibit deal signal thereon. On another aspect, when communications device 5 fails to retrieve account number in radio signal or retrieves incorrect account number, payment device 6 produces an unauthorized signal to communications device 5 that then produces and forwards a no-deal signal to mobile terminal 10 and/or to display device 20 for exhibition of no-deal signal.
For example, when drive device 3 has completed its program-controlled operation or when a force-quit button 24 is operated to terminate the game, drive device 3 generates a refund money signal of an unspent remaining amount, award, prize or jackpot obtained from the game if any. Drive device 3 may transmit refund money signal and management code signal to printer 11 and also to signal processor 5b of communications device 5 to store money amount to be refunded in signal processor 5b. Signal processor 5b may also transmit refund money signal to reception means 33 of mobile terminal 10 through communications interface 5a so that mobile terminal 10 may receive and write the refund money signal in memory means 34 of mobile terminal 10 to add money amount in memory means 34. Printer 11 may record data on the refund money signal and necessary management code signals from drive device 3 on recording medium or media and prepares a coupon of recording media for dispensation of the coupon from printer 11. In this way, a mutual intercommunication system may be established to transport and receive electronic signals between mobile terminal 10 and signal processor 5b through wired, wireless or radio or optical connection. Specifically, communications interface 5a may receive remotely operable signal from mobile terminal 10, and transmit it to signal processor 5b that may receive remotely operable signal from communications interface 5a. Signal processor 5b may also retrieve and produce signals of account number or debit card number for identifying the account owner or holder and the holder's PIN and/or ID number and monetary signals or a denomination signal contained in remotely operable signal and may then send the information to payment device 6.
After or before bills are extracted from stacker 9, it is put on a readout device 13 as shown in FIG. 3, but memory device 12 attached to stacker 9 is retained in the non-contact condition away from readout device 13 that may be operated to retrieve the following four kinds of information stored in memory device 12:
(i) Total amount and total number of bills stowed in stacker 9;
(ii) All denomination signals of bills;
(iii) All account numbers that identify account holders involved; and
(iv) The specific code signal identifying gaming machine 1 from which stacker 9 has been removed.
The information readout device 13 has retrieved from memory device 12 is compared with the information of bills removed from stacker 9 and with the information from communications device 5 to inspect whether or not they match.
In still another embodiment, gaming machine 1 may comprise an entry device made up of a plurality of choice switches, namely entry device 25 such as image switches on a display screen or made up of mechanical selector switches to be chosen to determine a denomination of bills for payment for games so that one or more of choice switches may be selected to determine one or more of different charge amounts to be paid for gaming to transmit one or more charge or denomination signals to signal processor 5b of communications device 5. On the other hand, when mobile terminal 10 transmits to communications device 5 remotely operable signal including holder's account number signal, communications interface 5a may receive account number signal from mobile terminal 10, and signal processor 5b may receive chosen charge signal from entry device 25 and holder's account number signal transmitted from mobile terminal 10.
In operation of gaming machine 1, a user may select either cash or electronic payment for games with gaming machine 1. Selecting electronic payment, he or she may operate entry means 31 of mobile terminal 10 to input money amount of gaming fees into CPU 35 that may synthesize a remotely operable signal by placing on a carrier wave the money amount of gaming fees and account number signal stored in memory means 34 and then transmit remotely operable signal to communications device 5 through transmission means 32. In this way, user may move closer to gaming machine 1 and allow mobile terminal 10 to lightly touch communications interface 5a while making mobile terminal 10 produce and transmit remotely operable signal from mobile terminal 10.
Then, FIG. 4 is a flow chart indicating further processing subsequent to transmission of remotely operable signal from mobile terminal 10 where processing moves on from Step 50 to 51, and so, signal processor 5b determines whether to receive remotely operable signal from mobile terminal 10. Receiving remotely operable signal through communications interface 5a in Step 51, procedure goes to Step 60 where signal processor 5b retrieves account number signal and monetary signal from remotely operable signal when remotely operable signal contains both account number and monetary signals. As mentioned before, in lieu of transmission of monetary signal from mobile terminal 10, monetary signal may be produced from entry device 25 to signal processor 5b. Then, signal processor 5b sends them to payment device 6 that receives account number and monetary signals and gains access to financial database 7 in Step 61 to determine whether the holder's account is legitimate and the amount of transaction fee is within a deposit balance of the account. When payment device 6 approves holder's account as legitimate and amount of transaction fee as being within a deposit balance of the account, it may withdraw the amount of transaction fee from holder's account at financial database 7 (Step 64).
Subsequently, payment device 6 produces a deal signal and a denomination signal as a monetary signal to signal processor 5b (Step 65) that then receives denomination signal; converter 5c converts denomination signal into a serial denomination signal to control device 8 of bill acceptor 4 that may receive serial signal in Step 66; and then, control device 8 transmits denomination signals to drive device 3 (Step 56). This allows drive device 3 to produce drive signals of the amount corresponding to denomination signal in accordance with built-in program in drive device 3, and sends drive signals to game hardware 2 to conduct a game. Then, gaming hardware 2 stops its operation in Step 57.
In Step 61, when payment device 6 does not approve holder's account because of incorrect account number or amount of transaction fee as being out of a deposit balance at the account, payment device 6 produces an unauthorized signal to communications device 5 that produces no-deal signal to mobile terminal 10 and display device 25 and finishes all procedure in Step 63. If remotely operable signal contains PIN and/or ID number, payment device 6 also decides whether it corresponds to one of pass-codes or secret number in financial database 7 in addition to identification of holder's account number at financial database 7. When PIN and/or ID number corresponds to pass-codes or secret numbers, payment device 6 produces an authorized signal, but, adversely, PIN and/or ID number does not correspond to pass-codes or secret numbers payment device 6 produces an unauthorized signal.
Game hardware 2 may include all money-operated electronic gaming machines such as slot machines provided with any drive device for generating drive signals after payment by denomination signals of bills considered genuine by bill acceptor 4. Control device 8 may retain its memory area the amount of transaction fee, holder's account number of financial database 7 and specific code identifying gaming machine and also transmit and write these information in memory device 12 attached to stacker 9. When payment device 6 makes unauthorized decision on payment in Step 61, it produces an unauthorized signal on payment to signal processor 5b (Step 62) to cease operations (Step 63).
On the other hand, when user selects cash payment, processing also begins with Step 50 in FIG. 4 and goes to Step 51 where without electronic signals received by signal processor 5b, and he or she inserts a bill or bills into bill acceptor 4 in Step 52, and, control device 8 receives detection signal from inlet sensor 21, while considering on whether inserted bill is genuine or not in Step 53. When control device 8 determines the bill to be inauthentic, it drives conveyor in the reverse direction to return bill to inlet of bill acceptor 4 (Step 58), and ceases the operation in Step 59. Adversely, when control device 8 considers bill to be genuine in Step 53, it determines the amount of bill (Step 54); stacker 9 stows the bill therein (Step 55); control device 8 forwards its denomination signal to drive device 3 (Step 56) to perform continuous operations and to stop the operation (Step 57). In this way, communications device 5 allows for cashless operation of gaming machine after verification of the monetary signal in remotely operable signal received from mobile terminal 10.
When drive device 3 has completed its program-controlled operation or when a player operates a force-quit button 24, drive device 3 immediately causes gaming hardware 2 to cease the game, and at the same time, drive device 3 generates and transmits to communications device 5 and printer 11 management codes and a refund money signal of an unspent remaining amount or payback amount data such as award, prize or jackpot obtained from the game if any, and communications device 5 transmits the refund money signal to mobile terminal 10. Then, printer 11 prints refund money signal on a printing media and dispenses a coupon thereof. In lieu of or in addition to dispensing a coupon, drive device 3 may send refund or payback amount data to communications device 5 that may convert the received refund money signal into a predetermined format and send them to mobile terminal 10. In this way, this system is very convenient because users can obtain goods or services from automated machine by real-time electronic payment for transaction while an operator of the automated machine can surely receive a payment without credit transaction.
FIG. 5 is a block diagram schematically showing another embodiment of the electronic payment system of prepaid type without automatic payment device 6 according to the present invention applied to gaming machine. In this embodiment, memory means 34 of mobile terminal 10 stores an electronic amount signal of prepaid money and at least one specific signal of PIN and ID numbers for identifying a holder of mobile terminal 10. Transmission means 32 of mobile terminal 10 emits a remotely operable signal including the at least one specific signal. A storage device 13 stores at least one of users' PIN and ID. Communications device 5 is connected to automated machine 1 and receives remotely operable signal emitted from mobile terminal 10 to retrieve at least one specific signal in remotely operable signal. Communications device 5 also receives a monetary signal indicative of a transaction fee necessary to drive automated machine 1 simultaneously with, before or after receiving remotely operable signal. Monetary signal may be contained in remotely operable signal so that it may be emitted from mobile terminal 10 and received by communications device 5. Otherwise, monetary signal may be produced by entry device 25 to communications device 5. When communications device 5 decides that monetary signal and at least specific signal are valid as a result of comparing the at least specific signal with that stored in storage device 13, communications device 5 produces monetary signal to drive automated machine 1 and also produces a deduction signal of transaction fee to mobile terminal 10. Subsequently, mobile terminal 10 receives deduction signal from communication device 5 to deduct transaction fee from prepaid money amount in memory means 34.
