That's exactly the main issue with the 16x84 cards (see attachment).
There are usually two flavours: with/without (external - to PIC) EEPROM.

Not much more expensiver than a normal 16x84 chip.

Anyhow, the pinout and functionality of the 12c50x fits perfectly to a
smartcard. I am wondering just how long it will take for a manufacturer to
use this ones for a card.
