Abstract

A card transaction settlement method in a point of sale (POS) system is described. More particularly, a payment by either the credit or debit card is made after an approval before the card transaction (ABCT) for a virtual transaction amount (VTA) is given, and in which when the transaction is completed, an approval after the card transaction (AACT) for the actual transaction amount (ATA) is requested for the transaction settlement. Settlement can be conveniently accomplished since conflict between the merchant and the consumer, caused by a difference between the transaction amount and the debited can be eliminated. The merchant has less of the financial risk for refund. A signature is not necessary on the signature form, resulting in that true non-cashier self-service sales can be introduced to the sales management system.

Claims

1. A method for performing an electronic card enabled transaction in a point of sale (POS) system having a self-service facility electronically connected to a card authorization center via a public network, the self-service facility including a card transaction terminal, the method comprising the acts of:

(a) requesting an approval-before-the-transaction (ABCT) of the authorization center for setting a virtual transaction amount (VTA) at the self service facility;

(b) determining whether the transaction is valid or not by validating the card and a corresponding account at the authorization center;

(c) approving the VTA if a determination has been made that the card and account are valid and responsively sending an approval signal to the self-service facility;

(d) executing the transaction at the self-service facility on the basis of the approval signal if the VTA is approved;

(e) requesting an approval-after-the-card-transaction (AACT) of the authorization center for setting an actual transaction amount (ATA) on the basis of the actual executed transaction;

(f) revalidating the VTA into the ATA at the authorization center and sending a confirmation signal to the self-service facility; and

(g) initializing the self-service facility for a next transaction and issuing a receipt for the actual executed transaction.

2. The method of claim 1 wherein the VTA is a maximum anticipated transaction amount which is set for a particular one-time transaction.

3. The method of claim 2 wherein the maximum anticipated transaction amount is determined by attributes of an item or service to be provided in the transaction.

4. The method of claim 3 wherein the item or service is one for which a payment amount is not determined before the actual transaction is executed.

5. The method of claim 3 wherein the attributes comprise at least one of:

a physical amount of the item;

availability of the item or service; and

a service time.

6. The method of claim 1 further comprising, before said act (a), the acts of:

reading the card in the card transaction terminal of the self-service facility; and

identifying a user using a entered personal identification number.

7. The method of claim 1 further comprising the acts of:

denying the VTA if a determination is made that one of the card and account are invalid; and

responsively sending an approval failure signal to the self-service facility.

8. The method of claim 1 further comprising canceling the ABCT for the VTA after one of act (a), (b), and (c).

9. The method of claim 1 wherein the ATA is prevented from exceeding the VTA.

10. A method for performing an electronic card enabled transaction in a point of sale (POS) system having a self-service facility electronically connected to a card authorization center via a public network, the self-service facility including a card transaction terminal, the method comprising the acts of:

(a) requesting an approval-before-the-transaction (ABCT) of the authorization center for setting a virtual transaction amount (VTA) at the self-service facility;

(b) validating the card and a corresponding account at the authorization center;

(c) approving the VTA if a determination is made that the card and account are valid and responsively sending an approval signal to the self-service facility, the approved VTA being the lesser of;

(1) a target VTA related to anticipated parameters of the transaction; and

(2) a value related to an available amount in said account;

(d) executing the transaction at the self-service facility on the basis of the approval signal if the VTA is approved and including restricting such execution to prevent an actual transaction amount (ATA) from exceeding the approved VTA;

(e) requesting an approval-after-the-card-transaction (AACT) of the authorization center for charging or debiting the account in the amount of the ATA on the basis of the actual executed transaction; and

(f) initializing the self-service facility for a next transaction and issuing a receipt for the actual executed transaction.
