Java Card

Hi All,

I am trying to implement an applet that stores a lot of data in persistent byte arrays on card. The problem is that the code for the project is rather comlicated and may be subject to change in the future. It is highly preferable to have any data stored on the card remain on the card whent the code is updated. One way of doing this is by having the main code in one applet and the data store in a separate applet.

This works well for small amounts of data that can fit in the APDU buffer. The problem I have is that the data store buffers are much greater than the size of the APDU buffer. The potential size of the buffers are only limited by the maximum size fo a byte array.

What other options are there for passing these buffers across the firewall? Are there any other options I can explore to acheive this?

Cheers,
Shane
