Climatic conditions influence the appropriate level and type of insulation. Establish whether the insulation is predominantly needed to keep heat out or in (or both). Insulation must cater for seasonal as well as daily variations in temperature (see âInsulation levels for your climateâ below). Source: SEAV 2002.
A SIM card, also known as a subscriber identity module, is a smart card that stores data for GSM cellular telephone subscribers. Such data includes user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages. Security features include authentication and encryption to protect data and prevent eavesdropping.
EMV card. An EMV card, also called a chip-and-PIN card or smart card, contains a special computer chip to store card account data. Unlike magnetic-stripe cards, every time an EMV card is used for payment, the chip creates a unique transaction code that cannot be reused, thus stymying counterfeit card fraud.
