The DS1963-F5 Monetary iButton from Maxim Integrated is a sophisticated and secure cryptographic iButton designed for applications where the integrity and security of the data are of paramount importance. This device is particularly well-suited for use in financial transactions, access control, and secure data storage.

Key Features

• High-Security Features: The DS1963-F5 is equipped with a unique 64-bit registration number, which ensures that each iButton is unique and tamper-proof. It also includes a Write-Only SHA-1 secret and a Write-Once, Read-Many (WORM) memory to prevent unauthorized data manipulation.
• Robust Memory Storage: With 4096 bits of user memory, the device provides ample space for storing sensitive information. This memory is divided into sixteen pages of 256 bits, with each page further subdivided into eight 32-bit blocks.
• Data Integrity: Each memory page can be independently write-protected or put into EPROM-emulation mode ("write-once") to ensure that once data is written, it cannot be altered or erased.
• Secure Authentication: The DS1963-F5 employs a challenge-and-response authentication protocol based on the SHA-1 algorithm, providing a high level of security for transaction and data verification processes.
• Durability: Encased in a rugged stainless-steel cover, the iButton is designed to withstand harsh environments and physical wear and tear, making it ideal for applications that require a durable and secure data carrier.
