10. Use of Smart Card

13. A contact smart card must be inserted into a smart card reader with a direct connection to a conductive contact plate on the surface of the card (typically gold plated). Transmission of commands, data, and card status takes place over these physical contact points. Contact smart cards have a contact area, comprised of several gold-plated contact pads, that is about 1cm square. When inserted into a reader , the chip makes contact with electrical connectors that can read information from the chip and write information back. Example: Contact smart cards

14. Contactless smart cards A contactless card requires only close proximity to a reader. Both the reader and the card have antennae, and the two communicate using radio frequencies (RF) over this contactless link. Most contactless cards also derive power for the internal chip from this electromagnetic signal. Example: Octopus card The Octopus card is a rechargeable contactless stored value smart card used to transfer electrical payments in online or offline systems in Hong Kong
