• Online shopping has gained popularity since people can shop anywhere as long as
they have access to Internet connection
• To some extent, despite various security mechanisms have been put in place, there are
still people who refuse to perform online shopping due to perception that it is not
secured, exposed to fraud and not trusted in actual delivery of the purchased item
• An alternative for purchasing items online by using contactless smart card stored with
point values is proposed based on following concerns:
 Changing the perception on security of online shopping in the sense that the use
of credit card or debit card for purchase will be cheated by the merchant
 The increasing need for offering product and services online via secured
transaction to compete and survive in business
 The increasing demand by current customers to shop more via Internet instead
of conventional shopping
 The importance of providing positive online shopping experience

• Payments and transactions in electronic have grown exponentially [Fiallos & Wu, 2005].
• Digital money offers flexible electronic payment with added security features that is required for
transaction, such as replicating the individual activity [Lee, Oh & Lee, 2004]
• Common elements in electronic payment methods are credit card, debit instruments, prepaid
payment services, cumulative collection services, payment portal services and mobile phone
payments [Vassilliou, 2004]
• Electronic payment (e-payment) offers several benefits:
 The need to only enter account information for making online payment [Hord, 2005]
 Convenient, helps in cost reduction and secured, which translates into reliable online
transactions for purchasing goods or services over the Internet [Humphrey, Pulley & Vesala,
2000]
 Automation of payment made electronically contributes to the reduction of the overall cost
for payment system [Appiah and F. Agyemang, 2006].
• Approaches and technologies have been introduced in ensuring the security of electronic
payment via the Internet:
 Cryptography is the most common security measures for online payment but slow in speed
and less efficient [Taddesse & Kidan, 2005]
 Credit cards with RFID technology is part of mobile phone architecture for secure e-payments
[Venkataramani & Gopalan, 2007].
 Use of fingerprint verification technique and steganography for confidence in online
shopping [Ihmaidi, Al-Jaber & Hudaib, 2006]
 Speech recognition and encrypted USB device as mechanisms for secured online
transaction [Panigrahy, Jena & Jena, 2010][Lin, Yuan &Qu, 2007].
 a new framework that omits hardware deployment at customer’s site for online shopping via
mutual authentication between merchant and customers
[Gupta and R. Johari, 2007]

• The user need to purchase the contactless smart card stored with point values at the
authorized retailer and register the purchase.
• User need to register his/her profile into the online shopping system and tie the card
purchased with the profile.
• Once user is registered, online shopping activity start: search for items, confirm
items to purchase and their quantity, agrees with terms and perform checkout.
• User then make payment after confirming the total amount of points required.
(Payment here means purchase the items using the points instead of typical actual
cash and subjects to availability of point values in the contactless smart card)
• The process ends and user waits for delivery of item according to specified time
stated in the system.

From the perspective of security and protection, the following is incorporated:
•SSL is enabled in the system to prevent the hackers tap during all transaction and
cover the whole website system
•Implement LINQ module which connect .NET web application to the database, thus
prevents SQL injection attempt
•Java Applet is used to communicate with the card reader, thus this enables code
signing certificate for Java.
•This system is a closed-environment, which means all users should login before there
can do the shopping and perform the transaction. So, since the log record exists in the
system, user activities within the system are recorded and can be tracked. Any
suspicious activities can be detected and the user tied-up with such activities can be
blocked.
•Since user need to tap the contactless smart card on multiple check point in
purchasing the product, it could prevent hackers from getting extra point from other
user or hacking to get illegal point without make the payment. This is because if
contactless card is not tapped at the particular check point, user cannot proceed to
next stage of purchase
