JavaCard OS

Dear Javacardos official,

I am looking for a java card, which should satisfy the below requirements:

- Contact interface (Dual interface is also OK)
- at last 3.5 kb RAM
- at least 100KB ROM
- ATR can be customized

Is there any cards that can fit my needs? Thanks in advance.

Do you have any requirement about the supported algorithms?

You can check the details of JC10M128C card.

In fact, we still have one java card -JC30M128CR that can fit your need, but it's not available in our online store now. You can contact javacardos@gmail.com for details.
