The Electronic Passport and the Future of Government Issued RFID-Based Identification

RADIO Frequency Identification (RFID) tags for the function of next-generation electronic product code (EPC) will become one of the most widely used devices in the near future an RFID. Once the tag is found valid, the back-end database will look up its product information for further processing. RFID tags are classified into three types: active, semi passive, and passive. Active tags contain batteries so that they can actively communicate with the reader. Semi passive tags also contain batteries but they wait for the reader’s query. As for passive tags, the power comes from the reader. The class of a tag represents the effective reading range. We analyzed the number of rounds required and the period of key update for practical deployment. RFID is an acronym for Radio Frequency Identification. RFID is one member in the family of Automatic Identification and Data Capture (AIDC) technologies and is a fast and reliable means of identifying just about any material object. This project can be used for security purpose where it gives information about the authorized persons and unauthorized persons. This can be applied in real time systems as such in recording the attendance, in the companies, airports for accessing the passports and in industries to know who are authorized. RFID is increasingly used with biometric technologies for security. Primarily, the two main components involved in a Radio Frequency Identification system are the Transponder (tags that are attached to the object) and the Interrogator (RFID reader). Communication between the RFID reader and tags occurs wirelessly and generally doesn’t require a line of sight between the devices. RFID tags are categorized as either active or passive. Active RFID tags are powered by an internal battery and are typically read/write, i.e., tag data can be rewritten and/or modified. An active tag's memory size varies according to application requirements; some systems operate with up to 1MB of memory. Passive RFID tags operate without a separate external power source and obtain operating power generated from the reader.
