Software Development Kit. A set of development utilities meant for writing software applications, usually associated with specific environments.
The de-facto standard to interface Personal Computers with Smart Cards (and smartcard readers of course). SpringCard PC/SC Readers comply with this standard. This makes those products usable on most operating systems, using an high-level and standardized API.
Low-level software that is similar to hardware features. This software operates by exchanging commands directly with an external device or with a specific software loaded in the product.
NFC Interface and Protocol-1 : This international standard defines a communication scheme (most of the time refered as “peer to peer mode”) where two peer “objects” are able to communicate together (and not only a PCD and a PICC). The underlying protocol is ISO 14443-A at 106 kbit/s and the Sony Felica protocol at 212 and 424 kbit/s.
A particular type of NFC Tag which contains an URI (action to be performed: open a web page, send a SMS, call a phone number...) and a Title (explanation to be displayed to the user).
An international association that aims to standardize the applications of NFC in the 13.56MHz range. Their main contribution is the NFC Tags specification.
Near-field communication. A subset of RFID, where the operating distance is much shorter than the wavelength of the radio waves involved. This is the case for both ISO 14443 and ISO 15693: the carrier frequency is 13.56MHz, leading to a wavelength of 22m. The proximity and vicinity ranges are shorter than this wavelength.
