MOBILE PAYMENT SYSTEM

Mobile Payment System Mobile Payment can be offered as a stand-alone service. Mobile Payment could also be an important enabling service for other m-commerce services (e.g. mobile ticketing, shopping, gambling…) It could improve user acceptance by making the services more secure and user-friendly. In many cases offering mobile payment methods is the only chance the service providers have to gain revenue from an m-commerce service.

Mobile Payment System(cont.) the consumer must be informed of: what is being bought, and how much to pay options to pay the payment must be made payments must be traceable.

Mobile Payment System (cont.) Customer requirements: a larger selection of merchants with whom they can trade a more consistent payment interface when making the purchase with multiple payment schemes, like: Credit Card payment Bank Account/Debit Card Payment Merchant benefits: brands to offer a wider variety of payment Easy-to-use payment interface development Bank and financial institution benefits to offer a consistent payment interface to consumer and merchants

Comparison Between internet and WAP technologies Wireless Application Protocol HTML JavaScript Wireless Application Environment (WAE) Other Services and Applications Session Layer (WSP) HTTP Transaction Layer (WTP) TLS - SSL Security Layer (WTLS) TCP/IP UDP/IP Transport Layer (WDP) Bearers: SMS CDMA PDC-P USSDwwwC.VSidDyarthipISlu-s1.c3om6 CDPD Etc.. 71

WAP Risks WAP Gap Claim: WTLS protects WAP as SSL protects HTTP Problem: In the process of translating one protocol to another, information is decrypted and re-encrypted Recall the WAP Architecture Solution: Doing decryption/re-encryption in the same process on the WAP gateway Wireless gateways as single point of failure
