Abstract
Communication between the near field communication (NFC) devices occurs in a very close distance of less than 10 cm. In the NFC-based payment system, close proximity between devices will increase the security of transactions. The disadvantage is the interaction between devices requires more physical activity of device owners because the device must be brought near to other devices some times. Besides requiring more physical activity, NFC-based interaction also takes a longer time because the device needs to be moved from one position to another. This paper proposed secure and efficient protocol that will reduce the physical activity of the device owners and reducing transaction time. The data exchange between merchant and payer will be executed without waiting for each other and one transaction will require two data transmissions are performed by the merchant and payer. Transactions are secured by the use of encryption on each data which sent by the merchant and payer. In addition, the protocol also guarantees the security of offline micro transactions and online macros transactions.
Highlights
Near field communication (NFC) is a short-range wireless technology which is the advanced development of RFID technology
Referring to the NFC Forum, NFC technology is currently used in three areas, namely sharing, pairing, and transaction
Wireless communication between the NFC devices, the NFC tag and the availability of NFC handsets support the development of contactless payment and the actual ewallet [1]
Summary
Near field communication (NFC) is a short-range wireless technology which is the advanced development of RFID technology. Wireless communication between the NFC devices, the NFC tag and the availability of NFC handsets support the development of contactless payment and the actual ewallet [1]. The process of communication between NFC devices implemented with the use of read / write tag facility, so it requires a protocol called protocol tag to tag. Protocols that are currently available is the protocol that manages the communication between the NFC with a peer to peer communication mode This protocol needs a sequential process during data exchange. This paper introduces the tag to tag protocol that is used in the macro and micro payments This protocol is different from the existing protocols, especially in the process of data exchange that does not require waiting for each other and which party should initiate the data exchange
