In this paper, we demonstrate a RFID tag being used for multiple purposes in a college or office premises. Here, we focus on two applications, access control and monetary transactions. The basic details of the user of the card and a fixed amount deposited by him/her will be stored in a database. The user can be granted or denied access to any desired place with the help of this card. Also, the same card can be used instead of cash where monetary transactions are involved, where the amount spent gets deducted from the balance associated with the RFID card of the user. We achieve this by using a Wi-Fi module ESP8266 for communicating the required details to the server over the internet. The goal of this project is to provide easy access control and a cashless environment in any workplace.
