BACKGROUND
Chen et al. (2010) described a mobile payment system for merchant micropayments that can be built on existing GSM and NFC architecture components. The author’s proposal leverages the SIM’s authentication and identification capabilities and used cryptographic primitives, which simplifies integration into the current mobile infrastructure.
The use of NFC for short range communication allows for possible integration with existing Point -Of-Sale (POS) equipment and the payment process from the customer and merchant’s perspective remains unchanged. Liu et al. (2010) proposed a trust model to protect the user’s security. The billing or trust operator works as an agent to provide a trust authentication for all the service providers. The services are classified by sensitive calculations. With this value, the user’s trustiness for corresponding service can be obtained. For, decision, three ranks: high, medium and low. The trust region tells the customer with his calculated trust value, which rank he has got and which authentication methods should be used for access. Authentication history and penalty are also involved with reasons. Yang et al. (2010) gives a general framework of online mobile payment and presents a new mobile payment pattern which advocates stratified extension and cascading agent based on stable and credible platform group. It also proposes a cross-bank unified payment platform to solve the difficulties of connection to banks. As a result, the authors got the regular effective and monitoring payment process which is of great manoeuvrability. The mobile payment process will be more reasonable and the transaction will be more secure. This framework was given to solve the problem of mobile applications that are difficult to be connected with the banks. Asghar et al. (2010) have surveyed five different models in the field of mobile payment in their research; then they were compared with MCDM evaluation methods applications. To implement a mobile payment service, there are many actors involved such as bank, operator and service provider. As an effective interaction role and in order to optimize efficient parameters for implementing a mobile payment solution a suitable business model is necessary. Since one of the most effective parameter to select an appropriate business model is the banks/operators structure of every country, the proposed business model is localized based on the Iranian banks/operators’ framework. The results of MCDM method indicate that the collaboration model is the most suitable mobile payment business model in Iran. Olsen et al. (2011) proposed a design of e-wallets. Interviews and formative usability evaluations have provided data for the construction of first a conceptual model in the form of low fidelity mock-ups. Chandrahas et al. (2011) focussed on some design considerations for Mobile Payment Architecture. For widespread adoption, interoperability is a key concern. The design of this architecture requires the user to know only the beneficiary’s mobile number in order to initiate a mobile payment. This is restrictive in the sense that only one bank account can be linked to a mobile number. To enhance flexibility it would be desirable, especially for merchants, to be able to link multiple bank accounts to a single phone number. The authors proposed an alternate and enhanced design that allows the flexibility to link multiple bank accounts while also allowing the transactions to be conducted with just the mobile number. Evaluated and compared these two designs on various criteria. The details of implementation issues, advantages and limitations are also presented. The analysis is a step towards the evaluation process of various design choices for mobile payment architectures.Researchers are continuously working in the field of mobile payments in order to increase the competitive advantage for the organisations and from user’s perspective as well.
