Roland Moreno patented the memory card in 1974. By 1977, three commercial manufacturers, Bull CP8, SGS Thomson, and Schlumberger, started developing smart card products. In March 1979, Michel Hugon from Bull CP8 was the first to design and . See more
A smart card is a device that includes an embedded integrated circuit that can be either a secure microcontroller or equivalent intelligence with internal memory or a memory chip alone. The .
Smart cards come in two varieties: memory and microprocessor (smart chip). Memory cards store data and can be viewed as small USB memory sticks with optional security. On the other hand, a microprocessor card can add, delete, and manipulate information in its memory on the card.
A smart card is a device that includes an embedded integrated circuit that can be either a secure microcontroller or equivalent intelligence with internal memory or a memory chip alone. The card connects to a reader with direct physical contact or with a .Memory smart cards only contain memory chips and can only store, read and write data to the chip. The data on these cards can be overwritten or modified, but the card itself is not programmable. So, data can't be processed or modified programmatically.
Smarts cards may have up to 8 kilobytes of RAM, 346 kilobytes of ROM, 256 kilobytes of programmable ROM, and a 16-bit microprocessor. The smart card uses a serial interface and receives its power from external sources like a card reader.The chip can be an embedded microcontroller or a memory chip. Smart cards with an embedded microcontroller have the distinct ability to store data, carry out on-card functions, like encryption and mutual authentication, and interact with a smart card reader. In addition, they are tamper-resistant and protect in-memory information using encryption.
Smart cards come in two primary flavors: Memory cards & Microprocessor cards (pg. 18). The very first smart cards were memory cards with re-write protected cells that could only be written to once (pg. 6).
What kinds of technology do smart cards use? Smart cards use a microprocessor chip to perform a number of functions. A single microcontroller chip, which is visible on the surface of the card, contains: RAM and ROM memory for storing data, both during computations and after; A microprocessor that handles data processing Memory-based smart card: This type of smart card is embedded with memory circuits. It stores read and writes data to a particular location. It is a straight memory card that is only used to store data or a protected memory card with restricted access to the memory and which can be used to write data.The smart card’s microprocessor processes and stores data, while the memory saves the data. Smart cards use built-in encryption algorithms to ensure data security. They interact with card readers through communication protocols defined by international standards such as ISO/IEC.
Memory Smart Cards: These cards have memory and some security logic processing capability but unlike smart cards do not have a microprocessor. These are utilized in easier applications. Microprocessor Smart Cards: These cards possess a microprocessor and can thus perform more robust activities and data processing as compared to the former.Smart cards come in two varieties: memory and microprocessor (smart chip).
