Abstract: A device, a method and a computer system to replace a bulky low tech, non-secure wallet with built-in security protocol is provided. A robust, high-memory capacity, portable miniaturized computer system includes a processing unit, memory, power source, reader and interface. The miniaturized computer is capable of storing large amounts of data and transmitting this data to a reader via a robust button interface, wireless transmitter or USB port or other connection configuration. The data contained within the computer is safeguarded by the need of the owner to access the data or remotely shut the computer down.
