Card's and issuer's public keys can be read from the chip, but these are not directly relevant to actual transaction signing.
Even if these keys was relevant, the important part is that they are public keys, not private keys. You cannot get card's private key from the chip by normal means (ie. without doing something that is classified as attack, be it side-channel, physical inspection or exploiting some firmware bug/backdoor).
