I think it means memory reader like cell phone/digital camera with memory card that you can plug in memory reader on your laptop. I never heard of smart card reader on the laptop.
If it is really a smart card reader then it should have pre installed software by your laptop Manufacturer.

Smart cards come in many different types.
They are all suppose to comply with the iso 7816 standard , but thats where the similarities end.
There are the cards that are used in dish network and directv recievers, and then there are others that are used by door locks, etc.
You can actually buy unprogrammed cards fairly cheaply.

I like to collect that very old directv cards, called F and H cards, NO these will not get you free tv .
They are reprogrammable for a variety of things and are usually free or thrown away.
They contain an asic and memory.
You can actually place a small application on the card and have it run to decrypt data when its in the reader without ever revealing the code running on the card.
Some are nearly 99.9% secure.
You do need special software and a knowledge of the cards in general to use them though.
I have used them to store passwords on my pc, lock down programs that require the card to run (similar to a dongle)_.
You can pick up readers for 10.00 or so.
Its a fun hobby.

There are loads of different types of smart cards - the problem is that you need the appropriate software for the type of card you wish to use.
Some cards are relatively basic, and simply provide a secure way to store confidential data (e.g. a security certificate for logging onto a secure web-site, or for connecting to a secure Wireless LAN) - the digital certificate file is much more secure than a password, and the smartcard provides a method of storing the data so that it cannot be copied or tampered with, as well as requiring a PIN to release the data. We have these at work to restrict access to workstations with access to confidential data. Instead of logging on with a username and password, you put your card into the reader and enter your PIN. No card, no access. Pull your card out - instant log out.
More advanced cards have more sophisticated CPUs or OSs on them - e.g. JavaCard, if you haven't already guessed, uses a Java CPU and stripped down OS. You can install simple applications onto the card for managing secure data. Even more sophisticated cards may add encryption accelerators for stronger encryption (128 or 256 bit encryption is a bit much for a standard smart card CPU).
This allows smart cards to actually perform processing themselves, instead of just referring to a server. E.g. several mass transit systems use smart-cards as reusable tickets. The card communicates with the reader, and the card records where you started the journey, where you got off, etc. and deducts the appropriate fare (upgrading the ticket as required, depending on the exact journey you take, but ensuring that you are only charged the lowest possible fare) - even if the card reader isn't connected to a server (e.g. on a bus). The secure communication system makes it highly tamper resistant, so that hackers can't add credit to a card, etc. At the same time there is no need for the readers to record the transactions, so no liberty-infringing database of people's movements.
