ROM applet

Post by Valks » Mon Jul 24, 2017 3:29 am

I always use APDU tool to download and install my applet in to card. Now I would like to develop in the embedded sector and not smartcards. Does anyone know whether there is a way to use the JCVM without at least the APDU stuff?
Does anyone know more details about ROM applets? Thanks...

You can have your applet masked into the ROM by a card manufacturer. This will remove the need for APDU's to install your applet. But you will still need to use APDU's for anything, including embedded applications on the device, to communicate with your applet. A Java Card applet is passive and does not perform any actions until it receives an APDU to process. I think you will find that using APDU's to load your applet will be quicker and easier than masking.
