Abstract: A method can include obtaining contact data corresponding to a set of contacts of an authorization card. The contact data can indicate a set of engaged contacts among the set of contacts. The method can include obtaining activation data corresponding to a set of predetermined engaged contacts among the set of contacts. The method can include determining, by comparing the contact data to the activation data, that the set of engaged contacts matches the set of predetermined engaged contacts. The method can include changing, in response to the determining, a state of the authorization card from an inactive state to an active state. The method can include permitting, in response to the changing the state, an electronic transfer of authorization data from the authorization card.

Abstract: In one general embodiment, a design structure is provided including a first delay line having at least one buffer, the first delay line being for shifting a clock, a second delay line having at least one buffer, the second delay line being for shifting data, and a logic block adapted to identify a predetermined section of a data window. Additionally, the logic block monitors a clock signal along predetermined portions of the delay line to identify the predetermined section of the data window. Once the predetermined section of the data window is identified the logic block forwards the data associated with the predetermined section to an output pin, with the proviso that no memory element is present, and with the proviso that no feedback line is present.
