  1. Mobile Commerce Prof. Euiho Suh 2004. 10. 18 POSMIS

  2. Contents • Definition and differences of M-commerce • Classes of M-commerce applications • Value Chain • Terminology and Standards • Attribute of M-commerce • The driver of M-commerce • Mobile Computing Infrastructure • Wireless Standards and Security • Applications : finance, shopping • Location-based Commerce • Limitations of M-commerce • Technical Limitation

  3. Definition of Mobile Commerce • Any transaction conducted over a mobile telecommunications network. • It represents a subset of all e-commerce transactions both in business-to-consumer and the business-to-business area

  4. Differences between M- and E-commerce • A permanent factor that makes difference between M- and the rest of the E- commerce is the possibility of the user to engage anywhere and anytime in M-commerce transactions; for some this is the crucial difference • The main functional distinction between the E-commerce in general and M-commerce are dynamic Location Based Services (LBS) that use the actual location of the terminal on earth in one way or the other to perform the transaction (cf. ordering taxi in a foreign city based on the positioning of the terminal and the taxi)

  5. Differences between M- and E-commerce (Cont.) • Further difference are the properties of the truly portable terminals: the simple UI facilities, slower processor, and smaller memory resources, as well as tiny energy reserves, as compared to PC:s or laptops • A fourth main difference is the relatively small wireless link transmission capacity offered to the terminals; although the capacity is increasing with every network generation (10 kbps, 100 kbps, 1 Mbps..), so is the capacity of the fixed networks; thus the gap will exist also in the future

  16. Mobile Computing Infrastructure (cont.) • Unseen infrastructure requirements • Suitably configured wireline or wireless WAN modem • Web server with wireless support • Application or database server • Large enterprise application server • GPS locator used to determine the location of mobile computing device carrier

  17. Mobile Computing Infrastructure (cont.) • Microbrowser • Mobile client operating system (OS) • Bluetooth—a chip technology and WPAN standard that enables voice and data communications between wireless devices over short-range radio frequency (RF) • Mobile application user interface • Back-end legacy application software • Application middleware • Wireless middleware • Software

  18. Mobile Computing Infrastructure (cont.) • Networks and access • Wireless transmission media • Microwave • Satellites • Radio • Infrared • Cellular radio technology • Wireless systems

  19. Wireless Standards and Security • M-commerce supported by • Standards • Security • Voice systems

  20. Wireless Standards • Wireless standards • Time-division Multiple Access (TMDA) • General Packet Radio Services (GPRS) • Code Division Multiple Access (CDMA) • CDMA One • Global System of Mobile Communication (GSM) • WLAN 802.11b (Wi-Fi) • Wideband CDMA

  21. Wireless Standards (cont.) • Wireless Application Protocol (WAP)—a set of communications protocols designed to enable different kinds of wireless devices to talk to a server installed on a mobile network, so users can access the Internet • Subscriber Identification Module (SIM) • Wireless Markup Language (WML) • Voice XML (VXML) • Enhanced Data Rates for Global Evaluation (EDGE) • Universal Mobile Telecommunications System (UMTS) • IPv6

  22. Security Issues • Viruses • Smart card security solutions • Voice communication can be intercepted by hackers • One solution is an embedded biometric add-on • Back-end security solutions public key infrastructure (PKI) and M-CERT (mobile certification)

  23. Voice Systems for M-Commerce • Hands-free and eyes-free operations increase productivity, safety, effectiveness • Disabled people can use voice data for various tasks • Voice terminals are portable • 2 ½ times faster than typing • Fewer errors

  24. Applications : mobile financial • Wireless electronic payment systems • Mobile phones become secure, self-contained purchasing tools capable of instantly authorizing payments over the cellular network for goods and services consumed • Micropayments—electronic payments for small-purchase amounts (generally less than $10)

  25. Applications : mobile financial (cont.) • M-wallet (mobile wallet)—a wireless wallet that enables cardholders to make purchases with a single click from their wireless devices • Bill payments directly from cell phone via: • Bank • Credit card • Prepaid arrangement
