How does a smart card work and how does it work?

Like mentioned earlier, smart cards are like the regular cards you can find around you (the same size and made of the same plastic material) but they have a memory chip contained in a contact pad. The contact pad bearing the embedded memory chip is the basis for which a transaction can be made using a smart card.

What kind of memory does a smart card have?

– crypto co-processor & random number generator (RNG) • memory: volatile RAM and persistent ROM & EEPROM – EEPROM serves as the smartcard’s hard disk • no power, no clock! A modern card may have 512 bytes RAM, 16K ROM, 64K EEPROM and operate at 13.5 MHz Important reason for low capabilities: cost!

What are the form factors of a smart card?

Form factors for smartcards • traditional credit-card sized plastic card – ISO 7816 • mobile phone SIM – cut-down in size • contactless cards – aka proximity card or RFID transponder/tag – also possible: dual interface • iButton • USB token 14 3 types of functionality 1.stupid card just reports some data

What are the functions of a stupid memory card?

3 types of functionality 1.stupid card just reports some data eg card shouts out a (unique) serial number on start-up 2.stupid smartcard aka memory card provides configurable file system with access control by means of PIN code/passwords or crypto keys or even simpler: irreversible writes

The smart card itself is powered by an external source, usually the smart card reader. A smart card communicates with readers either via direct physical contact or using a short-range wireless connectivity standard such as RFID or NFC.

How does a smart card connect to a reader?

They connect to a reader either by direct physical contact (also known as chip and dip) or through a short-range wireless connectivity standard such as radio-frequency identification ( RFID) or near-field communication ( NFC ). The chip on a smart card can be either a microcontroller or an embedded memory chip.

How does smart card resource manager service work?
