What is Mobile Commerce?

M-commerce is the buying and selling of goods and services through wireless handheld devices.

M-Commerce is the process of paying for services using a mobile phone or personal organizer.

M-Commerce is the use of mobile devices to communicate, inform transact and entertain using text and data via a connection to public and private networks.

Internet + Wireless + E-commerce = M-Commerce

Types of Mobile Commerce Two Major attributes mobility and reachability

Six categories◦ Time Critical Services

Flight timing change notifications, stock market prices alerts etc

◦ Location Aware and location sensitive Services Tracking trucks, Stolen cars.

◦ Identity Enacted Services Mobile banking, Nordea bank finland.

◦ Ubiquitous Computing and Content aware services Mobile News delivery, Distance education

◦ Business process streamlining Insurance Process

◦ Mobile Offices Security agencies, Office environment

Trends Towards Mobile Usage

Block Diagram

User Equipment:◦ A mobile phone or PDA acts as the user endpoint.

Access Network:◦ To provide authentication or to validate a users attempt to use the network

resources.

Service Network:◦ Provides personalized portals to many services, including commerce.

Enabling Technologies Wireless development

◦ First-generation wireless technology was the cellular phone◦ Second generation wireless technology, which includes digital cellular

phones, is currently in use worldwide◦ Third generation, or 3G technology enables wireless devices to send and

receive data as much as seven times faster than a standard 56K modem (0.4M ~ 2Mbps)

◦ Fourth generation, networks designed to uninterrupted high speed data transfer

Wireless Devices◦ Personal Digital assistants (PDA)◦ Digital cellular phones◦ Two way pagers

Enabling Technologies Contd.. Mobile Communication

◦ GSM (Global System for Mobile communication) is a digital mobile telephone system that is widely used in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA).

◦ General Packet Radio Services (GPRS) is a packet-based wireless communication service in GSM

◦ CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth.

◦ Mobile IP is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining their permanent IP address.

Enabling Technologies Contd.. Uncomplicated User Interface

◦ WAP◦ I-mode

WAP◦ Developed by WAP forum, a consortium of nokia, ericsson, motorola◦ WAP 1.0

WAP Gateway Acts as a interpreter GPRS and High Data rates

◦ WAP 2.0

I-mode◦ NTT Docomo◦ Only in japan.◦ iHTML◦ Compatible sites divided into two categories

Content provided by official providers Content provided by unofficial providers

Enabling Technologies Contd.. Proposed Solution for the improvement of m-commerce

Mobile RFID Technology

◦ RFID Tags on almost all products.◦ Product information◦ Product ordering ◦ Product receiving◦ Product transfer management system.

Enabling Technologies Contd.. Product ordering system architecture.

Enabling Technologies Contd.. As Large scale RFID technology more and more products in

the world will have tags Use a smart phone or PDA to get product information Mobile RFID reader EPC code is read into the mobile RFID reader and

transferred to the mobile device Through wireless network and the gateway mobile device

can access internet The application queries the ONS using the EPC code to get

the address of the PML server Retrieving product relative information from PML server If both the products match then order the product through m-

commerce server

Existing Applications

Challenges in M-Commerce Security:

◦ Authentication is a property by which the correct identity of an entity or party is established with a required assurance.

◦ Security Remains a threat . User input (voice, text, gestures)

◦ Human computer interaction technology should be developed for voice recognition, gesture recognition and natural language

processing of the text. IPv4:

◦ A bridging support should be developed for embedded devices to communicate through Internet.

Ubiquity: ◦ The devices should be capable of ubiquitous computing.

E-Commerce Vs M-Commerce

Conclusion M-Commerce will be at least as successful as e-commerce if

the underlying technology and standards accentuate the advantages and minimize the disadvantages.

The technology certainly is worth working on its just the matter of going in the right direction and make its right use in order to get to the desired results.

Questions???

Q.1: Why the WAP 1.0 Failed and WAP 2.0 was created?Ans 1: WAP 1.0 failed because of security reasons. Before

transmitting the information to the server it was decrypted at the WAP gateway. That is why WAP 2.0 was created to address this fault in WAP 1.0

Q.2: How mobile RFID technology would help to remove the peoples concern in receiving m-commerce products in terms of safety and quality?

Ans 2: When you receive the products you ordered, you can scan the tag to get what stores in it. The information will be checked with the order terms you signed in Internet , the retailer’s regulations and the commerce laws via existed mobile communication technology and software. According to the result , customer will determine to get it or reject it. In this way the customers can be assured of quality of the product and more customers will be encouraged.

Q. 3: Explain briefly from the following diagram how the system architecture of product ordering works in Mobile RFID system?

Ans 3: Use a smart phone or PDA to get product information EPC code is read into the mobile RFID reader and

transferred to the mobile device Through wireless network and the gateway mobile device

can access internet The application queries the ONS using the EPC code to get

the address of the PML server Retrieving product relative information from PML server If both the products match then order the product through m-

commerce server
