Automatic dialing system

Abstract

The invention relates to a credit card dialing apparatus for use in automatically dialing account numbers, security codes and phone numbers into telephones. The apparatus includes a credit card size device having a memory, encoder, speaker, microphone and switch embedded into a circuit board for inputting and outputting specific information depending on the use of the card. The circuit described accesses the account by tones or signals fed through the receiver or direct data input from a small databus. In another embodiment, a microprocessor unit having a keyboard, microprocessor memory, encoder, a speaker unit and microphone as well as an alphanumeric display is utilized. This system permits the user to input the desired numbers and provide serial dialing and identification for particular sources.

Description

This application is a continuation of application Ser. No. 07/496,038, filed 20 Mar. 1990 now abandoned.

FIELD OF THE INVENTION

The invention relates to a credit card size microprocessor operated telephone dialer/credit card.

BACKGROUND AND DISCUSSION OF THE INVENTION

To place long distance telephone calls often the telephone dialer must either reverse the charges or recall a charge number for inputting into the telephone system. Particularly

DETAILED DISCUSSION OF THE PREFERRED EMBODIMENT

As can be seen in FIG. 1, the apparatus includes a keypad for inputting certain information into input/output module 20. The processor 22 is connected to the input/output module 20 through control lines 26 and also is connected to memory 24 through address and data busses. A data bus also connects input/output module to processor 22 and memory 24. The input/output module 20 is connected to input microphone 16 and separately to output speaker 18. In this way after the desired numbers have been input into the system corresponding to a number to be used, the user can access the number by pressing the appropriate key on the keyboard. To use as a phone credit card the card is placed against the receiver and the number, through use of tones corresponding to touch tone frequencies, will be dialed into the receiver. Only the number being dialed will be immediately input into the receiver. Once the credit card request tone is sensed by the microphone, the user charge number will then be input into the receiver again corresponding to touch tone frequencies to complete the call.

The card can also be used via the data bus as a phone card or regular credit card (i.e. bank credit card, etc.) in a similar manner. The card would be inserted into a phone or an input unit of a cash register/computer allowing the charge if the appropriate PIN number has been entered.

With reference to FIG. 2, the front of the card, there is shown a display and a keypad with function keys and decimal numbers 30. In this manner the speaker and microphone can be placed against the mouthpiece of the telephone, once the appropriate number has been selected. In another embodiment the card can have the speaker 18a and microphone 16c located on the same side of the card with the keypad and display.

There is also provided a sequence key 42, which enables the user to shift from one number to the next in sequencing the calls. The telephone number and identification number are shown on display 14C. For direct dial long distance calling there is a special key 34 for this purpose. Clear key 36 is provided to clear a number from the register for inputting a new number. Scroll keys 46 and 56 are provided and operate with the microprocessor to scroll through the numbers until the desired number is obtained. By pressing the scroll keys 46 and 56 the name, address and corresponding data will be displayed simultaneously or sequentially by the display means on the face of the card. A sequence key 42 is provided to dial several numbers in sequence. Starting with a particular number and inputting according to the sequence key, numbers will continue to be dialed until a particular connection is made. A local dialing key 37 is provided to eliminate the area code for local dialing. Finally, an enter key 40 is provided for inputting new data.

Once the data has been properly input into the system, it can be used in the following manner. The user presses the sequence key until the desired data is displayed on display 14C. This is the data that will be input to the system once operated properly. In utilizing the device as a phone card, the card's speaker is placed over the mouthpiece of the receiver and the user then presses the direct long distance dial key, if it is a long distance number. After a programmed delay period the number will be dialed using the tones according to a touch tone system. Once the number is completed the system will stop until the appropriate tone which identifies the need for the account number is sensed by microphone 16c. Once the tone is sensed, the speaker 18a will then be actuated to input the account number using the touch tone system.

Where a number of numbers are to be dialed until a connection is made, the sequence key 42 can be operated. In this system the sequence key is initially pressed and the card will automatically seek the next set of data. If no data is stored in a particular block, the sequence addressing step will move to the next block of data until a number is located. At this point the operation of the program will stop until a direct call is dialed or the sequence key is again pressed. Dialing would be accomplished again as discussed above. Similarly, rather than automatically sequencing, the user can scroll to the desired number by pressing the scroll key 46 and 56.

To change a number or an identification the processor is operated to arrive at a particular data location. This data is cleared by actuating clear key 36 and a new identification number and telephone number is input using the decimal keys 30. Once the desired number has been input the enter key is hit to place it in memory.

With scroll keys 46 and 56 the user can input the identification numbers, actuating the scroll keys until the data corresponding to the identification number is found.

As can be seen by FIG. 4, another embodiment of the apparatus includes switch 60 that activates the microprocessor with memory 62 that in turn outputs to speaker 58. The microprocessor 62 is connected to an input/output bus 64. In utilizing this device as a phone card, after the card has been preprogrammed, the user can place the speaker 58 over the receiver and press switch 60 activating the microprocessor outputting to the speaker 58. The speaker emits the touch tone frequencies corresponding to the user's account number thus allowing access to the phone system or completing the dialing procedure. The input/output bus 64 could be used for programming the card or outputting information directly to a phone system, cash register, or computer.

As seen in FIG. 5, the apparatus consists of a switch 80 connected to a clock 81 and a shift register 82 that outputs via databus 83 to the encoder 87 that in turn outputs to speaker 88. In this way after the card has been preprogrammed the user can place the speaker 88 over the receiver and press switch 80 activating the clock and shift register outputting to the encoder 87 in turn outputting to the speaker 88, or place the card on the receiver and when the credit card request tone is sensed by the microphone 86 the input/output circuitry 84 activating the clock 81 and shift register 82 outputting to the encoder 87 in turn outputting to the speaker 88. The speaker emits touch tone frequencies corresponding to the user's account number thus allowing access to the phone system or completing the dialing procedure. The input/output bus 84 could be used for programming the card or outputting information directly to the phone system, cash register, or computer.

The actual size of the device to house the elements discussed above is shown in FIGS. 6, 7 and 8. The card 90 as shown has a typical credit card configuration with the logo and other information on front 92. The near side 93 includes the microphone and speaker that can be made small enough not to significantly interfere with the thickness as shown. These elements can be embedded in the card and the circuit board to reduce the amount of space required.

The above has been a detailed discussion of the preferred embodiment of the invention. The full scope of invention to which Applicant is entitled is defined in the claims which follow and their equivalents. The specification should not be interpreted to unduly narrow the scope of invention to which Applicant is otherwise entitled.
