OMH (Open Market Handsets) is an initiative within CDMA networks, that assures that the possibility of changing the handset or the operator is given at any time. Led by the CDMA Development Group (CDG), the OMH allows the purchase and use of an OMH device for any OMH-conform operator network. All operator and subscriber data have to be stored in the R-UIM or UICC card instead of writing it in the device. Furthermore, OMH offers device manufacturers the opportunity to sell their full-featured devices across the entire CDMA ecosystem of OMH-enabled operators instead of only selling them to one operator.
PCD (Proximity Coupling Device) is the generic term for readers within ISO/IEC 14443. The PCD is emitting an electromagnetic field and able to model all requests on the carrier frequency. All communication is initiated by the PCD and its range is about 10cm (proximity).
A Proximity Integrated Circuit Card (PICC) is a contactless Smart Card that is able to operate within a radius of approximately 10 cm of the card reader. As a passive card, it purchases power from the card reader device.
A Removable User Identification Module (R-UIM) is a removable ID chip for mobile phones made for the CDMA system. In the beginning of CDMA, there was no need for a Smart Card because all subscriber relevant information was stored in the handset itself. The R-UIM card holds a user's personal information such as name and account/ID number, mobile phone number, phone book, text messages and further settings. It is the corresponding item to the (U)SIM card used within GSM or W-CDMA networks.
RFID (Radio-Frequency Identification) is a technology to identify objects or persons using electromagnetic radiation. The RFID-system mostly consists of two parts: there is a transponder with a unique code on one side and on the other side a reading device. This device evaluates and saves the received code information so that the object/person carrying the transponder can be identified.
SIM Application Toolkit (SAT) consists of a set of commands defined for the communication between a card and a handset with the goal to enable the (U)SIM to initiate actions which can be used for various value-added services. This enables the SIM to build up an interactive exchange between a network application and the end user.
The Smart Card Web Server is one of the newest developments within telecommunication technologies and offers a Smart Card based mobile internet access. It is enabled by an USIM which is capable of supporting standard web technologies like HTML pages and HTTP.
Subscriber Identity Module (SIM) is an application on a chip card used mainly for authentication purposes based on secret numbers as IMSI and Ki and special algorithms to enable the identification of a mobile phone user within the GSM-network. The access/use is protected by a PIN.
As the SIM is the dominating application on this types of Smart Cards, the card (hardware) itself is often named SIM too.
A smart card, a chip card or integrated circuit card (ICC) is the general term for a card which contains one or more semiconductor chips. A chip card may be in the form of a memory card or a microprocessor card.
Smart Card Reader
A smart card reader is a device plugged to a computer that allows to send commands to a smart card.
