The SLE 5542 is a type of contact smart card, which is a plastic card that contains an embedded microchip that can be read and written to through physical contact with a smart card reader.
The SLE 5542 smart card is manufactured by Infineon Technologies AG, and it has a 256-byte EEPROM (electrically erasable programmable read-only memory) that can store data and applications. The SLE 5542 is commonly used in applications such as access control, electronic cash, and loyalty programs.
The SLE 5542 smart card uses the ISO/IEC 7816 standard for communication with the smart card reader, and it supports secure authentication and encryption through the use of a unique secret key stored on the card. This makes the SLE 5542 suitable for use in applications that require secure storage of sensitive data.
To use the SLE 5542 smart card, a compatible smart card reader is required. The reader communicates with the card through physical contact, and can read and write data to the card’s EEPROM memory. The SLE 5542 also supports a number of security features, such as password protection and access control, to ensure that only authorized users can access the data stored on the card.
