The present invention relates to a contactless RF card reader having a wireless communication function. More specifically, wireless communication with a host computer enables authentication and access control and time and attendance management by enabling authentication with three LEDs and a buzzer. The present invention relates to a PC interface type RF card wireless reader for easier and convenient processing by applying to attendance management, drinking water management, and parking management.

In general, smart cards can store a large amount of information, such as personal information such as bank accounts, social security numbers, as well as user and transaction information, and can be used as a simple electronic money. In particular, this important information can be protected by a microprocessor, data protection and encryption. In addition, whether the user of the card is a legitimate user uses a personal identification number called a PIN (Personal Identification Number).

Smart cards are largely divided into memory type and microprocessor type according to the type of built-in IC. Memory-type cards include no microprocessor, memory only, or security features in memory, and are used for public phone cards or data storage.

If the microprocessor is built, the operation can be performed in the card, so it can use complex encryption functions for data protection. EEPROM is used as memory used to store data. It can also be divided into contact and contactless cards, depending on how data is read from the card.

A contact card is a card that can be used only after the card is inserted into a reader or a terminal and the contacts are in contact with each other. The input and output process of the information is carried out with the voltage supply required to drive the IC circuits in the card through the contacts.

On the other hand, a contactless card, like a bus card, can be read within a certain distance (within 10 cm) of the terminal by the terminal. Since the contactless card cannot supply the voltage from the outside, the inductive current is obtained by using the coil embedded in the card. It also contains a simple wireless communication circuit for data input and output to and from the terminal.

In the case of a contact card, the contact must be touched each time it is used, so there is a high possibility of being subjected to electric shock or damaged contacts.

On the other hand, the contactless card does not have this disadvantage, but has a disadvantage in that the manufacturing cost is higher than that of the contact card. Of course, dual cards that can be used in both ways are also in use today.

However, when the reader is installed to read the contactless card as described above, it is fixedly installed at one place, and the people of the management carry the RF card and take it close to the reader to check the installation of the fixed reader. Installation work is complicated because the line construction must be parallel, there is also a problem that the processing speed is lowered due to communication overload or communication delay because the communication with the server must be maintained at all times.

The present invention is to solve the above-mentioned conventional problems, its purpose is to handle various situations such as access control, time and attendance management, attendance management, parking management, etc. more easily and conveniently through the wireless terminal to be applied to the situation At the same time, by providing a wireless communication with the host to provide a PC interface-type RF card wireless reader to have a large number of applications by simplifying installation and convenience of movement.
