4.1.1. What is Contactless Smart Card Technology?
-
Contactless Smart Card Technology makes use RFID Induction Technology for a contactless smart card to communicate with a Smart Card Reader/Writer. The contactless smart cards operate in close proximity with an antenna inside the reader for data transfer. Typical Contactless Technology application includes micro payments, loyalty programs, automatic fare collection systems, and physical access control.

4.1.4. What is PC/SC?
-
PC/SC is a specification for smart card integration in computing environment which is a communication protocol between the smart card reader and smart card. It offers interoperability of the products from different vendors by providing a standard high level programming interface which increases the flexibility and independence of PC-based software.

4.1.5. What is SAM?
-
The SAM or Secure Access Module is an additional feature in a Smart Card Reader that can enhance the level of security in your Smart Card based application. Normally card authentication is implemented in PC or application level. However with the presence of a SAM, mutual authentication can be implemented between card and reader which means that the PC will not perform the authentication but it will be done via card to reader and reader to card authentication making your system more secure and less prone to hacking.
