E-Purse System: Smart Card Electronic Purse

Stored value on a smart card: reload at a counter, pay at the POS with PIN protection, even without an internet connection

An e-purse (electronic purse) keeps a money balance on a smart card. BSD Infotech’s e-purse application issues and reloads cards, deducts payments at POS terminals and logs every transaction, with mutual authentication between card and terminal and PIN protection for the cardholder.

Overview

What Is an E-Purse?

An e-purse is a prepaid balance stored on a smart card. The card is loaded with value at a reload terminal and pays at POS terminals, where the amount is deducted from the card. Because the card and terminal authenticate each other directly, payments complete in a fraction of a second and do not need a live network connection.
Process

How the E-Purse Application Works

Card issued→Reload→Tap / insert at POS→PIN check→Balance deducted→Transaction logged

Card issuer

Issues each smart card with the reload and POS terminal public keys, the card’s private key, the initial balance and the PIN.

Reload terminal

Increases the balance on the card according to user input, after card and terminal authenticate each other. Several reload channels can be used in one deployment.

POS terminal

Deducts the purchase amount from the card, with the same mutual authentication as the reload terminal.

Transaction logging

Every transaction is logged for reconciliation and reporting.

Security

Security Built into Every Transaction

PIN authentication

Cardholder PIN with a configurable retry limit; a card can be locked until it is re-validated by an authorised terminal or administrator.

Mutual authentication

A terminal only works with genuine, provisioned cards, and a card only with registered terminals.

Encrypted key exchange

Prevents balance values from being tampered with in transit.

Terminal key management

Each terminal is provisioned individually, so terminals can be added or revoked easily.
