This type of smart card consists of electrical contacts which are used to connect to the card reader where the card is inserted. The types of smart cards based on connection to the card Reader include the following. It can be a contact or contactless reader. It interfaces with the PC or a microcontroller using the USB port or RS232 serial ports. Finally, the payment system otherwise the authentication system does the necessary task.Ī smart card reader is a device to which the card is connected either directly or indirectly using RF communication.After that, the payment system otherwise an authentication system authenticates the operator whether the information provided by the card matches through the database.Once the card reader reads the data from the card, then it passes the data toward the payment system otherwise authentication system.It is placed into the card reader to read the data from the card.The working process of this mainly includes the following steps. The utilization of contactless cards is being enhanced quickly because of their convenience to use. But, there are two kinds of cards like contact as well as contactless cards. Therefore it helps you in transactions through the point of sale (POS) otherwise another medium to perform transactions. In this card reader, the contact pad approaches in contact through the card reader & carries out the processing. When the contact pad is detached from the smart card then it is no longer smart. This card includes an embedded memory chip that includes a contact pad. Smart Card Working ProcessĪ smart card does not function alone and it requires a smart card reader to work properly. This smart card is fabricated with either a memory chip otherwise a microprocessor to store the data and to connect with the system. Usually, it is a plastic card included with an integrated circuit. It is used to control the data accessing & data manipulation. It is connected to the host computer or controller via a card reader which gets information from the card and accordingly passes the information to the host computer or controller. These are mainly used for access control in government authorities, educational institutions, etc.Electronic benefits transfer or EBT cards are mainly used for the allotment of government benefits.In Hospitals, these cards are used to store the details of patients.The payment cards like debit cards and credit cards are issued by banks as well as commercial organizations.
