Embodiments relate generally to computer software and computing devices, and more particularly, to a system, an apparatus and a method configured to segregate data at an interface of a computing device to facilitate on-line electronic payment transactions. In one embodiment, a method includes presenting fields configured to accept a first type of data and to accept a second type of data for an on-line electronic payment transaction. The method includes generating an initialization signal for transmission to an isolated data management system to initialize a portion of a memory associated with first type of data, responsive to an interaction with a field, receiving data from the field, and generating a save signal to save the data from the field in a portion of the memory. This can be responsive to a second interaction with the field.
