Smartcard have distinctive features like portability, by the reduced size, and the low cost, in order to be used on a large scale. Associated to these characteristics, find out limitations of the hardware’s resources, related fundamentally with memory and processing capabilities. These and others limitations of Java Card technology constitute significant limitations for the smartcard applications developers, and in general. In this work, is presented a smartcard application development model with Java Card technology that allows to extend memory and processing capabilities, making use of the computer's hardware resources. This model guarantees the safe environment that is characteristic of this device type. The proposed development model provide a mechanism for storage data associated to smartcard applications off- card, and for the execution of high cost computational algorithms, that for runtime or complexity is more feasible to perform off- card. With this new model is intended to significantly increase the applications and use of the smartcard, in connected and controlled environments like companies and institutions.
