Hence its necessary to preserve privacy and security to our bank account so that our personal and account details will not be revealed to these applications. In the proposed systems digital tokens are used along with the Block chain technology to provide security for our personal and account details. For the same enough evidence is noted. Key Words: Block chain, Card payment, Digital Tokens, RFID, Cashless 1. INTRODUCTION India is a developing Country. Since Our nation is going to be Digitalized Nation, Digitalized Nation means using the concept of Paperless, Cashless. Cashless transactions occur with the help of Credit cards, Debit cards, bank transactions, Google Pay, PayPal etc. Digital payment means paying or transferring money to a person or entity by means of digital mode. A person's record is required to be connected to the advanced wallet to stack cash in it. The meaning of an electronic instalment framework is a method for paying for a products or administrations electronically, rather than utilizing money or a check, face to face or via mail. A case of an electronic instalment framework is Google Pay. Nowadays block chain technology is coming into existence. Block chain is Internet database technology. It consists of blocks which are interrelated. In these blocks we store the data. RFID tags are devices that have read only chip which is used to store unique number. It is also called as Radio Frequency Identification. This RFID does not have processing capability. We aim to provide security to the digital payment system. In this paper we discuss about the various methods through which we can make payment. 2. Literature Survey According to the author Balaji rajendran et. Al it is suitable to introduce Digital tokens to protect and provide privacy and security to the intermediary system using cryptographic principles. DTE supports the transaction between the remunerator and receiver. In this methodology the customer requests the digital tokens from bank. If there is sufficient amount in the account then the digital token exchanger will provide the tokens to the customers, else tokens will not be generated. We can request the DTE for any number of tokens we want. Using these tokens the customer can make payment to any person or to the entity. The validity of this token is only three months. After the validity period of the token we can remit the token. The Advantage of this proposed model is scalable, practical, and straightforward to implement by the prevailing payment intermediaries. [1]. According to the author Alexander Schaub et. Al Reputed frameworks should be security protecting so as to work appropriately. Building a reputed system that is security saving with no trust suppositions is certifiably not an easy task, So the author proposes a model block chain with blind signatures. Blind Signature is a form of digital signature where the content is disguised before it is being used. Examples of blind systems are cryptographic election systems, digital cash schemes. Reputed systems would be extremely important, in light of the fact that there is a lot less hazard that the protection of the clients could be ruptured. Such a reputed framework for online business applications, is recommended as security is guaranteed. The advantage in this system is the security is guaranteed as we are using blind signatures along with the block chain concept [2] According to the author T.Chai et. Al current systems suffer from security and privacy issues, especially in financial applications. So, the author proposes token based block chain technology. It has three concepts they are Universal token structure, Authirazation Management and Token based booking method. Ethereum adopts account-based accounting method. To enhance the scalability Etherum introduced smart cards. Bit Coin adopts UTXO and POW which supports transactions of currency and exhibits less scalability and low efficiency. To avoid these problems the author proposed block chain and system based on tokens. It provides high security and it requires verification from the owner in each n every step. Advantage of this token system is it will resist attack from new users, prevent attacks from old users and it avoids global rollback. Disadvantage of the system is it is difficult to implement unified token structure of complex scenarios.[3] According to the author Thomas S. Heydt-Benjamin et. Al secure payment can be done through RFID. In spite of a large number of RFID-empowered installment cards as of now A Survey Paper on Secure Digital Payment
