Abstract: The present invention is directed, in part, to electrical connectors for engaging a mating electrical component, methods and systems comprising same. Specifically, in one embodiment, there is provided a system for engaging a mating electrical component that includes a first and second electrical connector adapted to engage different portions of the mating electrical component and spaced apart from each other. The first electrical connector has a guide post at a first end opposite said second electrical connector and the second electrical connector has a guide post at a first end opposite first electrical connector. The guide posts are adapted to support the mating electrical component therebetween, and the first electrical connector and the second electrical connector are mounted on the circuit substrate in a mirror image relationship.

Abstract: Card reading apparatus capable of accepting different sized disconnectible electronic cards, including memory storage cards such as larger smart cards and smaller S.I.M. (signature identification module) cards, includes a reader housing assembly which encloses a connection chamber. A conventional connector in the connection chamber has a plurality of resilient contacts projecting toward a course to be taken by a memory storage card as it is inserted through an entry slot into the housing assembly. Each memory storage card is rectangular and includes a similarly sized and positioned plurality of contact pads thereon for mechanical and electrical engagement, respectively, with the plurality of resilient contacts on the connector in the connection chamber when inserted into the connection chamber through the entry slot and advanced to a seated position.
