Abstract

A method includes a point of sale (POS) terminal receiving transaction data indicative of a purchase transaction, and detecting, by a card interface associated with the POS terminal, the presence of an integrated circuit (IC) payment card. The process also includes the POS terminal receiving indications of a plurality of data objects stored in the IC payment card, selecting a payment application based at least in part on the transaction data and the indications of the plurality of data objects, retrieving an account number associated with the selected payment application, and then executing the selected payment application to handle the purchase transaction.

First claim

What is claimed is:

1. A method for handling a purchase transaction comprising:
receiving, by a point of sale (POS) terminal, transaction data indicative of a purchase transaction, wherein the POS terminal operates in accordance with a plurality of payment applications stored in a memory;
detecting, by a card interface associated with the POS terminal, the presence of an integrated circuit (IC) payment card, wherein the IC payment card stores a plurality of data objects that each includes a respective account number, and wherein each of the data objects corresponds to a respective one of the plurality of payment applications;
receiving, by the POS terminal via the card interface from the IC payment card, indications of the plurality of data objects stored in the IC payment card;
selecting, by the POS terminal, a cash card payment application from among the plurality of payment applications based at least in part on the transaction data and at least in part on the indications of the plurality of data objects received from the IC payment card;
requesting, by the POS terminal via the card interface from the IC payment card, a current pre-authorized balance of the cash card payment application;
determining, by the POS terminal, that the pre-authorized balance is sufficient to cover an amount due for the purchase transaction;
requesting, by the POS terminal via the card interface from the IC payment card, a cryptogram reflecting the pre-authorized balance; and
receiving, by the POS terminal from the IC payment card, the cryptogram to consummate the purchase transaction.

2. The method of claim 1 , wherein selecting the cash card payment application further comprises, determining, by the POS terminal, that the amount due for the purchase transaction is less than a predetermined threshold amount.

3. The method of claim 1 , further comprising, prior to receiving the indications of the plurality of data objects stored in the IC payment card:
determining, by the POS terminal, that none of a cash card data object, a credit card object, or a debit card object is present; and
declining, by the POS terminal, the purchase transaction.

4. The method of claim 1 , wherein selecting the cash card payment application from among the plurality of payment applications comprises comparing, by the POS terminal, a total amount of the purchase transaction with a transaction type floor limit.

5. The method of claim 1 , wherein the plurality of payment applications include the cash card payment application and at least one of a credit card payment application, a debit card payment application, a loyalty card payment application, and a transit system access application.

6. The method of claim 1 , wherein the IC payment card operates in accordance with the EMV standard.

7. The method of claim 1 , wherein each of the payment applications comprises executable program code instructions stored in the memory.

8. A point of sale (POS) terminal for handling purchase transactions, comprising:
a POS terminal processor;
a device interface operably connected to the POS terminal processor;
a card interface component operably connected to the POS terminal processor for communicating with an integrated circuit (IC) payment card;
a memory operably connected to the POS terminal processor and storing a plurality of payment applications, wherein the memory also stores instructions configured to cause the POS terminal processor to:
receive transaction data indicative of a purchase transaction via the device interface;
detect the presence of an IC payment card via the card interface component, wherein the IC payment card stores a plurality of data objects that each includes a respective account number, and wherein each of the data objects corresponds to a respective one of the plurality of payment applications;
receive, via the card interface from the IC payment card, indications of the plurality of data objects stored in the IC payment card;
select a cash card payment application from among the plurality of payment applications based at least in part on the transaction data and at least in part on the indications of the plurality of data objects;
request, via the card interface from the IC payment card, a current pre-authorized balance of the cash card payment application;
determine that the pre-authorized balance is sufficient to cover an amount due for the purchase transaction;
request, from the IC payment card, a cryptogram reflecting the pre-authorized balance; and
receive, from the IC payment card, the cryptogram to consummate the purchase transaction.

9. The apparatus of claim 8 , wherein the memory also stores a plurality of payment profile subprograms, each of the subprograms certified as compliant with a payment processing standard that applies to the POS terminal, wherein a first subprogram operates to handle an offline purchase transaction without requiring a cardholder verification method (CVM), and a second subprogram operates to handle an online load transaction requiring a CVM and verification of the CVM by a remote computer; and
wherein the POS terminal processor is operative with the cash card payment application program to switch among the plurality of payment profile subprograms while the IC payment card is interfaced to the card interface component.

10. The apparatus of claim 9 , wherein the plurality of subprograms comprises the first subprogram, the second subprogram, and a third subprogram for handling an online load transaction that does not require entry of a CVM.

11. The apparatus of claim 10 , wherein the POS terminal processor is operative with the cash card payment application to:
initiate an offline purchase transaction with the IC payment card interfaced to the card interface component using the first subprogram;
determine that a pre-authorized balance stored in the IC payment card is less than a total amount for the purchase transaction;
store a context for the purchase transaction, the context including the total amount for the purchase transaction and a payment card account number associated with and retrieved from the IC payment card;
discontinue execution of the first subprogram;
initiate execution of the third subprogram;
transfer at least part of the stored context to the third subprogram; and
execute an online load transaction using the third subprogram, the online load transaction increasing a pre-authorized balance stored in the IC payment card using a script received from a remote computer.

12. The apparatus of claim 11 , wherein the POS terminal processor is further operative with the cash card payment application to:
establish a first clearing record, the first clearing record for clearing the online load transaction;
discontinue execution of the third subprogram;
resume execution of the first subprogram;
provide at least part of the stored context to the first subprogram;
complete the offline purchase transaction using the first subprogram;
establish a second clearing record, the second clearing record for clearing the offline purchase transaction; and
discontinue execution of the first subprogram.

13. The apparatus of claim 12 , wherein the POS terminal processor is further operative with the cash card payment application to:
initiate an offline purchase transaction with the IC payment card interfaced to the card interface component and using the first subprogram;
determine that a pre-authorized balance stored in the IC payment card is less than a total amount for the purchase transaction;
store a context for the purchase transaction, the context including the total amount for the purchase transaction and a p
