This paper will show the differences between contact smart cards, contact less smart cards and intelligent tokens (iButton) with respect to RAM, ROM and EEPROM and other related aspects.
Smart cards and intelligent tokens uses encryption algorithms to provide the required level of data security to prove the identity of the person sending/receiving the message and that the message hasn’t been altered.

There are many custom command sets used by smart cards but most of them are based around the ISO-7816 specifications, which set out the communication protocols ad defines the commands used by smart cards in great details.
“Smart cards allow thousands of times the information storable on magnetic stripe cards. In addition, smart cards are more reliable, perform multiple functions and are more secure because of high security mechanisms such as advanced encryption and bio-metrics. Smart cards can and will hold a large amount of personal information, from medical/health history to personal banking and personal preferences.”
In both smart cards and intelligent tokens the maximum ROM is 64kb and the minimum is 24kb in smart cards. ROM in other hand has a maximum of 134kb in intelligent tokens and a minimum of 512 Bytes in some smart cards. The maximum EEPROM is 8kb in smart cards and the minimum is 2.25kb in smart cards also. Use this paper for your reference and study.
