Implementation of the Enhanced RC5 (ERC5) Algorithm in an RFID-based Payment Scheme

In a business, it is important to note that owners should always make sure that they give a hassle free service to their customers to attract their attention and will eventually, gain their trust and continous patronage of their service and RFID offers a solution for this concern. Traditional way to collect payment is still in use up to this day. This paper intends to implement the use of RFID based payment scheme for the DMMMSU-NLUC Fasfood center. Moreover, the ERC5 algorithm has been used to encrypt sensitive information in the system for security purposes. Result shows that the authors were successful in implementing ERC5 as an encryption algorithm. Result also shows that the ERC5 outperforms the classic RC5 algorithm in both speed and work efficiency category.
