PROVIDING BEST CARDS WORLDWIDE Smart Cards Smart Cards: A Brief Overview A smart card is a plastic card with an embedded integrated circuit (IC) chip. This chip enables the card to store and process information, making it more secure and versatile than traditional magnetic stripe cards. Types of Smart Cards: Contact Smart Cards: These cards require physical contact with a card reader to establish a connection. They are commonly used for bank cards, SIM cards, and employee ID cards. Contactless Smart Cards: These cards use radio frequency identification (RFID) technology to communicate with a reader wirelessly. They are often used for public transportation cards, access control cards, and mobile payments. Dual Interface Smart Cards: These cards combine the features of both contact and contactless smart cards, offering flexibility and convenience. Key Features and Benefits: Enhanced Security: Smart cards use encryption techniques to protect sensitive data, reducing the risk of f...
