Secure and Immutable Payment Algorithm Using Smart Cards and Hyperledger Blockchain

By doing digital transactions there is a lot of risk of hacking and also the rising incidence of online fraud. When utilizing the smart cards system, users are concerned about fraud, security problems (hackers), the lack of availability of up-to-date information, and hidden fees. Recent studies clearly show that card-not-present fraud, skimming fraud, and website cloning method has been used more frequently in the smart card system.

Card systems face a variety of issues, including connectivity issues, password forgetfulness, fraud fears, lack of understanding, others technological issues. The scope of the research is limited to the card is particularly used in ATM and online purchase only but by using this proposed system using block chain aggregator we can use any plastic card a to purchase any things transparently and efficiently.
