Two piece dual layer transaction device

A two-part dual layer transaction device comprising:

• a computerized master unit powered by rechargeable battery, the master unit storing a plurality of aggregated financial transaction accounts in datasets and capable of connecting wireles sly to a data network and accessing at least one network server, the master unit having a housing with a length, a width, forming at least one planar side and an internal volume;
• a transaction card element having a rectangular planar form factor having a first planar surface and a second planar surface, acceptable for use as at least one of a debit card and a credit card;
• wherein the transaction card element is coupled to the master unit in an idle state and may be uncoupled by the user for the purpose of using the card element in a physical financial transaction;
• wherein the master unit and transaction card are attracted to and held adjacent to one another via aligned electrostatic micro-structures provided by a silicon film between the at least one planar side of the housing and all of the planar surface of either the first or second planar surfaces, and at least one dataset is transferred to the transaction card thereby enabling the transaction card to physically accomplish a financial transaction at a financial terminal.
