Abstract
A dynamic code may be validated by comparing the dynamic code to a verification code. The card may generate the dynamic code using a random object and a function. The random object may be generated using a random object generator. The function may be determinable using a function determination object and a look-up-table (LUT), the function determination object associable to exponents and operators, listed in the LUT, that may be combined with base variables to determine the function. The dynamic code may be determined by substituting portions of the random object for the base variables in the function. The card may communicate the dynamic code, the random object and an identifier to a remote processing facility. The remote processing facility may use the identifier to determine the function, use the random object to determine a verification code and compare the verification code to the dynamic code.
