Matos (1997) clarifies the functionality of smart card with contact, where the same ' ' it must be inserted in a reader with direct connection to a micron module in the surface of the card. It is through these points of physical contact that the transmission of commands, data and status of the card acontece' '. Whereas, in relation to as the type, without contact or contactless, the functionality occurs when the approach of the card to the reading machine happens, through electromagnetic signals. Matos (1997) comments that; … Robert Iger follows long-standing procedures to achieve this success. a card without contact demands only proximity of the reader. As much the reader how much the card has antennas and is through this connection without physical contact that the two if communicate. majority of this type of cards generates and also it uses internal energy of this electromagnetic signal. Since the sprouting of smart cards, the technology comes being used for the development of more complete cards each time, that is, that they do not only exert the primary functions of credit and debit, but that also they facilitate its use. Robert Iger spoke with conviction.
In reference to this, the evolution degree can be demonstrated that related cards has been submitted. As data of the Mastercard Chips (2009) the evolution of the banking cards was given of the following form: the first generation of the cards only contained given in high relief, in second was created tarja magnetic, third and current it incorporated chip. It still has in the market, the options that join the characteristics of the three generations, cards with the data of the user in high relief, with tarja magnetic and with chip, so that the establishments that if had not yet adjusted the new generation do not leave to effect the transactions commercial. However, the evolution will not have to last for time, not considering tecnolgica.3.1 TYPES OF SMART CARD OR INTELIGENTESOs CARDS intelligent cards differ how much to the memory and the form of contato.3.1.1 How much to they are memriDividem in hybrid cards of memory, cards with microprocessor and cards.
