michaelpapet.com writes "IBM has ported/developed their Javacard smart card operating system for Sharp's 1MB smart card. Read Sharp's announcement here. Interesting features include: AES encryption; elliptical curve encryption; and 1MB of storage. Sharp's smart card package claims to be almost as small as a normal smart card package. In an industry that can considers 64K of memory a luxury, 1MB is staggering. Read Sharp's original 1MB smart card announcement here. Is this a 'Build it and they will come...' kind of solution? How small is an 'almost as small' smart card IC package?"

I work for IBM with smart cards. My team directect Sharp the the JCOP (Java Card Open Platform) operating system over a year ago. The 1MB is rewritable storage. The OS is stored in ROM. It is a simplified version of Java (the JavaCard standard) that requires very little in the way of resources.
Functionality is added to the card by securely loading JavaCard applets to the 1MB of storage. More info on JCOP can be found here.
