A smart card is a compact and secure device embedded with a microprocessor that stores, processes, and updates information. Unlike traditional debit or cash cards, smart cards have the capability to memorize all transactions, making them highly valuable for numerous applications, from financial transactions to storing medical records.
Historical Context
The concept of smart cards was first introduced in the late 1960s and early 1970s. The breakthrough came when Roland Moreno, a French inventor, patented the first smart card in 1974. Since then, smart card technology has rapidly evolved and is now ubiquitous in various fields.
Types and Categories
- Contact Smart Cards: These require physical contact with a reader.
- Contactless Smart Cards: Use radio frequency identification (RFID) technology to communicate with the reader.
- Dual-Interface Smart Cards: Combine both contact and contactless technologies for added versatility.
- Cryptographic Smart Cards: Employ cryptographic techniques for enhanced security.
Key Events
- 1974: Patent of the first smart card by Roland Moreno.
- 1983: Introduction of smart cards in the banking sector by Bull CP8.
- 1999: Launch of the Common Electronic Purse Specifications (CEPS) standard for e-purses.
Detailed Explanations
Components
- Microprocessor: The brain of the smart card, responsible for data processing and storage.
- Memory: Stores information such as personal data and transaction history.
- Card Operating System (COS): Manages the interaction between the microprocessor and the external environment.
How It Works
The smart card is inserted into or tapped against a reader, which communicates with the card’s microprocessor. The reader authenticates the card and initiates a transaction or data exchange process.
