What are smart cards?
They are credit card size plastic cards embedded with a micro-controller and/or a memory chip, that will store or transect data depending on its particular function. This data is usually associated with either value, information, or both and is stored and processed within the card’s chip. Smart cards are used for many different reasons in varying settings. The uses for smart cards include identification, authentication, financial, mobile phone (SIM), data storage and application processing.
Smart cards have been widely used in the financial sector for many years now, in order for banks to offer their customer more flexibility securely. In more recent years smart cards have been applied to the transport system allowing travellers to move around more efficiently and to retail loyalty schemes.
What are the Types of Smart cards?
There are different types of smart cards based on how they are read by the card reader device;
- Contact Smart Card – the most common type of smart card and is required to be physically inserted into a card reader to work.
- Contactless Smart Card – can be read by the reader when the card is in close proximity and does not necessarily require physical contact with the reader. the communication between the card and reader happens via radio wave frequency.
- Hybrid cards – this type of card contain both contact and contactless interfaces that are not connected and can give increased range of function. This is rare type of card, not widely used.
How Do Smart card Readers work?
A device that is used to read or process
Smart cards require a reader to access the information or to process the application stored within the chip. There are 2 ways to connect to the reader;
- Physical contact readers – use electrical contacts on the card chip to connect with the reader when the card is inserted.
- Contactless readers – uses radio frequencies such as Short-range wireless connectivity (RFID) or Near field communication (NFC) to read the card when it comes into close proximity to the reader.
How are Smart Cards used in Access control?
