Abstract: An apparatus, system and other techniques for a smart card device, one or more host devices and a modular computing system comprising a smart card device and one or more host devices are described. For example, an apparatus or example smart card device may comprise one or more processor circuits, an interface coupled to the one or more processor circuits, the smart card device sized to be removably inserted into a host device and the interface configured to removably couple the smart card device to the host device, and logic, at least a portion of which is in hardware, the logic to configure the smart card device based on one or more characteristics of the host device. Other embodiments are described and claimed.

Abstract: Apparatuses and a method are described. For example, an apparatus or example smart card device may comprise a casing to enclose at least a portion of a processing logic, a first plurality of contact pads disposed substantially in a row near an edge of a first side of the casing, and a second plurality of contact pads disposed in a centralized group, the second plurality of contact pads substantially separate from the first plurality of contact pads.
