BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to pre-paid telephone calling cards and also
relates to discount coupons for goods and services. More specifically, the
invention relates to a telephone calling card with an integral coupon, and to a
method for using the card to place a telephone call and redeem the coupon.

2. Description of the Related Art

A pre-paid telephone calling card allows a person to make a telephone call
without making a payment at the time the call is made. Rather, the cost of the
telephone call is debited from a corresponding account during each call. Prior
to making the telephone call, the person purchases the card in exchange for a
payment that represents the initial balance of the account. The seller may be
the company that provides the telephone service or may be a reseller of cards
purchased from such a service provider or sold on behalf of the service
provider. To make a telephone call to another party, the purchaser first makes a
telephone call to the service provider, typically through a toll-free
connection. The toll-free telephone number is typically printed on the card. The
person then provides information to the service provider that identifies the
account. Typically, the person simply uses the buttons of the telephone keypad
to enter a number that is printed on the card. Such a number is commonly known
as a personal identification number (PIN). Nevertheless, other types of pre-paid
telephone calling cards have a magnetic stripe or similar medium that stores the
PIN or other identifying information on the card in an electronically readable
manner. Telephones having a means for reading a magnetic stripe can thus read
the number or other identifying information automatically. The service
provider's computer telephony system or switch receives and compares the
identifying information to information in a database to verify the authenticity
of the account. If the account is authentic, the system instructs the caller,
typically by means of voice prompts, to dial the telephone number of the party
to whom the caller wishes to speak. The system then completes the call by making
the connection through the appropriate telephone companies and debits the
caller's account by an amount proportional to the duration of the call. When the
account balance falls to an amount not sufficient to pay for a call, the system
prevents any further telephone service. The person may then discard the card and
purchase a new card. Some service providers provide a feature that allows a
person to recharge a card, i.e., increase the balance of the corresponding
account, by making further payment. Nevertheless, the vast majority of telephone
calling cards are considered disposable. Such a card has no further function
once the balance of its corresponding account is depleted.

A discount coupon is a token, typically a slip of paper, that a consumer can
redeem at a retailer of goods or services for a discount on the purchase price.
A discount coupon is typically imprinted with the name of the product or service
and the amount of the discount. For example, it may be imprinted with the text:
"25.cent. Off Purchase of Blort Cola." It is also typically imprinted with a bar
code to facilitate redemption. A person may obtain coupons by cutting them out
of a newspaper advertisement or other publication, by receiving them in a mailed
advertisement, by removing them from a product or its packaging, or by other
means. The manufacturer of a product is typically the party that causes the
coupons to be issued. For example, the manufacturer or its agent, such as the
manufacturer of the (fictitious) Blort brand cola in the example above, may have
coupons printed in a newspaper advertisement. To redeem a coupon, the person
typically presents the coupon to the retailer at the time he purchases the goods
or services, and the retailer discounts the purchase price by the amount
indicated on the coupon. The retailer subsequently presents the coupon to the
manufacturer of the product for reimbursement of the discount amount. A consumer
may sometimes redeem coupons in other ways, such as by mailing them to directly
to the product manufacturer.

Although coupons are distributed to potential consumers of products and services
in various ways as described above, it would be desirable to distribute them in
yet other ways to increase the number of potential purchasers of a product or
service. This need and others are satisfied by the present invention in the
manner described below.

SUMMARY OF THE INVENTION

The present invention relates to a pre-paid telephone calling card and method
for using it. A user purchases the card and uses it to make a telephone call in
the conventional manner via a service provider system associated with the issuer
of the card, but after the account balance corresponding to the initial payment
is depleted (or at any other suitable time), the user presents the card to a
retailer or other merchant for redemption in the manner of a discount coupon for
products or services. The discount may be in any amount up to the full price of
the goods or services. In addition, in certain embodiments of the invention the
products or services may be advertised by providing an audible message to the
user when the user accesses the service provider system. The product or service
and the amount of the discount are provided on the card in a visually and/or
electronically readable format. In other words, the product or service
identification and the discount amount may be printed on the card or recorded on
a magnetic stripe, bar code, solid-state memory chip, or other suitable device.
In embodiments in which the information is electronically readable, the retailer
or other merchant can use suitable electronic equipment such as a bar code
scanner or magnetic stripe reader to obtain the information.

The foregoing, together with other features and advantages of the present
invention, will become more apparent when referring to the following
specification, claims, and accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

For a more complete understanding of the present invention, reference is now
made to the following detailed description of the embodiments illustrated in the
accompanying drawings, wherein:

FIG. 1 is a top plan view of a telephone calling card of the present invention;

FIG. 2 is a bottom plan view of a telephone calling card of the present
invention;

FIG. 3 illustrates a system relating to a telephone service provider that issues
a calling card, a consumer who purchases the card and uses it to place a
telephone call via the service provider's system, a retailer who redeems the
card for the consumer as a product coupon, and the manufacturer of the product;
and

FIG. 4 is a flowchart illustrating the method of the present invention.

DESCRIPTION OF A PREFERRED EMBODIMENT

As illustrated in FIG. 1 the front surface of a telephone calling card 10
displays suitable graphic or textual indicia to convey to a user that the card
is a telephone calling card and to convey its denomination. The illustrated card
10 includes the text "$5 PHONE CARD" to convey that the card has a value or
denomination of five dollars and thus can be used to make one or more telephone
calls totaling no more than five dollars in cost. Card 10 also displays suitable
graphic or textual indicia to convey to a user that the card may be used to
obtain a discount on the purchase of products or services in the manner of a
conventional coupon. Card 10 includes, for purposes of illustration, the text
"SAVE 50.cent. ON PURCHASE OF BLORT COLA" to convey that the card has a
redemption value of fifty cents for a (fictitious) product known as Blort cola.
In other words, the user may use card 10 in the manner of a coupon to obtain a
discount of fifty cents off the purchase price of the identified product. As
illustrated in FIG. 2, the reverse surface of card 10 displays a telephone
number for the user to call to contact the service provider. The number is
typically a toll-free number, which in the United States typically includes the
prefix "800" or "888." Card 10 includes, for purposes of illustration, the
(fictitious) telephone number "800-555-1234." The reverse surface of card 10
also displays an access code or personal identification number (PIN). Card 10
includes, for purposes of illustration, the PIN "5678". The reverse surface also
includes a magnetic stripe 12. Recorded on magnetic stripe 12 is the PIN,
information identifying the product, and the discount or redemption amount.
Other information may also be recorded on magnetic stripe 12. The information is
recorded in any suitable manner known in the art that may be read by magnetic
stripe readers. Magnetic stripes and magnetic stripe reader machines are
well-known in the art and widely used in systems relating to debit-type cards.
Therefore, magnetic stripe machines and the manner in which the information is
recorded on and read from stripe 12 are not described in this patent
specification. The reverse surface further includes a bar code 14 that also
encodes the information identifying the product and the discount or redemption
amount. Bar codes and bar code reader machines are well-known in the art and
widely used in coupon redemption and point-of-sale systems. Therefore, bar code
reader machines and the manner in which the information is recorded or encoded
on and read from bar code 14 are not described in this patent specification. It
should be noted that although both a magnetic stripe 12 and a bar code 14 are
included in the illustrated embodiment, in other embodiments only one or the
other or neither may be included. Moreover, magnetic stripe 12 and bar code 14
are only examples of suitable types of data recording media. In other
embodiments the media may include, for example, a semiconductor memory chip or
similar solid-state memory device. Such chips are well-known in debit cards
known as "smart cards," which may include not only integral memory chips but
also microprocessors and other devices.

As illustrated in FIG. 3, a user, generally indicated by reference numeral 16,
purchases card 10 from a telephone service provider, generally indicated by
reference numeral 18. The purchase price corresponds to the initial balance of
an account maintained by service provider 18. User 16 can make a telephone call
using card 10. Thus, user 16 uses a telephone 20 to call service provider 18 by
dialing the toll-free number indicated on card 10. From that point, the service
provider's computer telephony system or switch 22 conducts the transaction with
the user. Telephony switch 22 causes the call to be answered and provides voice
prompts to the user directing him to enter a PIN using the telephone keypad or
to pass card 10 through a magnetic stripe reader on telephone 20. Because such
computer telephony switch systems are well-known in the art and widely
commercially available, telephony switch 22 is not described in further detail
in this patent specification. A feature of the invention is that telephony
switch 22 also provides an advertising message or other voice message relating
to the product identified on card 10. For example, the message may be: "Don't
forget to give your calling card to your local Blort cola retailer for fifty
cents off your next purchase of Blort cola."

Telephony switch 22 completes the call in the conventional manner. Thus, it
retrieves from its database the balance of the account corresponding to the PIN
that the user entered and determines whether it exceeds a predetermined
threshold amount, such as zero dollars. More commonly, rather than zero, the
threshold is the smallest amount that is sufficient to pay for the smallest
increment of telephone calling time for which the service provider normally
charges, typically a few cents. If the account balance is sufficient to pay for
this increment of calling time, telephony switch 22 prompts user 16 to dial the
number of the party, generally indicated by reference numeral 24, to whom user
16 desires to speak. Telephony switch 22 completes the connection via the public
telephone network or one or more long-distance telephone companies, thereby
causing the telephone 26 of party 24 to be rung. If party 24 answers and the
call is thus completed, telephony switch 22 periodically debits the account
during the call. If the account balance falls below the threshold amount,
telephony switch 22 terminates the call.

When the account balance is depleted or, for that matter, at anytime after user
16 purchases card 10, user 16 can redeem card 10 at a retailer, generally
identified by reference numeral 28, for the indicated discount on the purchase
of the product 30. Thus, user 16 gives card 10 to retailer 28 at the time user
10 purchases product 30, and retailer 28 discounts the purchase price by the
amount indicated on card 10. In the illustrated example, retailer 28 discounts
the purchase price of the cola product by fifty cents. Retailer 28 may read the
relevant coupon information encoded in bar code 14 in the conventional manner.
The manufacturer of product 30, generally identified by reference numeral 32, in
addition to selling product 30 to retailer 28, accepts card 10 and reimburses
retailer 28 for the discount or redemption amount. Although card 10 is redeemed
through retailer 28 in the illustrated embodiment, it should be noted that in
other embodiments of the invention card 10 may be redeemed in any other suitable
manner known in the art for redeeming coupons. For example, user 16 may send
coupon 10 directly to manufacturer 32 or to another party. User 16 may receive,
for example, a reimbursement on the purchase price or may receive discounted or
free products, services, options to purchase products or services at discounts,
tickets, or other value.

At the time user 16 purchases product 30 from retailer 28, retailer 28 may issue
user 16 other coupons (not shown). Systems and methods are known in the art for
automatically issuing coupons at the point of sale for products related to a
product a consumer purchases. Therefore, the details of such systems and methods
are not described in this patent specification. Nevertheless, such systems and
methods may be included as an additional feature of the present invention.

Manufacturer 32 pre-arranges with service provider 18 to provide the coupon
information on the calling cards that service provider 18 sells and to provide
the voice messages advertising the products that manufacturer 32 sells. Although
in the illustrated embodiment, service provider 18 causes the calling cards to
be sold to consumers, in other embodiments manufacturer 32, its agent or a
related party may sell calling cards directly to consumers. The transactions and
business relationships described in this patent specification are intended to be
only exemplary, and others will occur readily to persons skilled in the art to
which the invention pertains.

FIG. 4 summarizes the method of the present invention by which user 16 uses card
10 to make telephone calls and also to receive a discount on product 30. At step
34 user 16 purchases card 10 from service provider 18 or through another party,
such as a convenience store. At step 36 user 16 makes one or more telephone
calls via service provider 18. As indicated at step 38, at the time user 16
contacts service provider 18 to make a call, in addition to the conventional
voice prompts provided to user 16, service provider 18 provides advertising
messages or other voice messages relating to the product identified on card 10.
At step 40 user 16 redeems card 10 as a coupon at retailer 28 upon purchasing
product 30.

It will be evident that there are numerous embodiments of the present invention,
which, while not specifically described above, are clearly within the scope and
spirit of the invention. Consequently, the above description is considered to be
exemplary only, and the full scope of the invention is to be determined solely
by the appended claims.
