Hybrid Smart CardĪ hybrid type is designed with both microprocessor & memory. This kind of card allows safe access to the chip of the card with either the contactless otherwise contact interfaces of the smart card. The dual interface smart card is designed with both the interfaces of contact & contact. It allows for data processing and manipulations and can be used for multi-functioning. The data in files and the memory allocation is managed via an operating system which can be a fixed operating system or dynamic operating system.

It also consists of specific sections of files with each file associated with a particular function.

These cards consist of a microprocessor embedded onto the chip in addition to the memory blocks. It can also be rechargeable or a disposable card which contains memory units that can be used only once. It can be a straight memory card that is only used to store data or a protected memory card with restricted access to the memory and which can be used to write data. The data cannot be processed or manipulated. It can only store, read and write data to a particular location. These are cards that only consist of memory circuits. Types of Smart Cards based on their Functionalities and Configuration include the following. It usually receives power from the reader via an electromagnetic signal. Rather it consists of an antenna with which it is used to communicate using a Radio Frequency band with the antenna on the reader. This type of smart card communicates with the reader without any physical contact. The electrical contacts are deployed on a conductive gold plated coating on the card surface. 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.
