Method and apparatus for linking converted applet files

Abstract

A smart card (100) which includes a non-volatile read / write memory (230), a resolve buffer (505), a processor (205) connected to the memory (230) and the resolve buffer (505), and an installer module (210) configured to cause the processor (205) to receive computer code having unresolved references into the memory (230), and further configured to cause the processor (205) to perform a method for resolving unresolved references. The method including steps for copying the contents of the memory (230) into the resolve buffer (505), detecting unresolved references in the computer code, determining the resolved reference for each of the detected unresolved references, updating the contents of the resolve buffer (505) with the resolved references, and replacing the contents of the memory (230) with the contents of the resolve buffer (505).

Description

technical field [0001] The present invention relates generally to the field of smart cards, and more particularly to an improved smart card and a method for resolving unresolved references in converted applet files loaded in the smart card. Background technique [0002] Most customers are familiar with and have used credit cards, debit cards, automated teller machine (ATM) cards, stored value cards, and the like. However, for many transactions, the current trend is to move away from these types of cards and to use a device commonly referred to as a "smart card". A smart card is a plastic, credit card-sized card that includes electronics (a chip) embedded in most of the card's plastic. Smart cards use an embedded microprocessor and memory elements within a chip rather than just an embedded magnetic strip that stores information. [0003] Because smart cards have a chip, they can be programmed to operate in a variety of different capabilities, such as stored value cards, cre...
