What is a contactless smart card?
A contact intelligent card is a type of intelligent card that - unlike Chip cards - is processed without having to come into contact with the intelligent card reader or be transferred by a slot. Instead, the contactless intelligent card uses the RFID brand. RFID is a type of microchip that is combined with an antenna. When it is inserted into the object, this object can be monitored. The size of RFID brands varies, but some may be as small as a large rice grain.
A contactless intelligent card works with an interaction with a RFID reader or a scanner capable of emitting radio waves. The RFID or scanner reads the signal that raises the RFID antenna. RFID then returns the signal and usually adds some type of confirmation data. RFID systems have a "reading range" - the distance at which the RFID brand can read a reader or scanner, and this can be a restriction in some applications.
advantages of contactless intelligent card included. Whatever they are for ÚControls in a shopping situation or verification, contactless smart cards are more comfortable because they are faster. As a result, contactless smart cards are popular for applications such as verification, data storage and identification. Specifically, this is played at the international level of use, such as paying fare in transit systems, employee identification signs, driving licenses, electronic passage and cashless credit cards.
Most contactless intelligent cards have the same dimensions as a credit card. These can be "closeness" cards that are only read cards and are used for purposes such as access to the device or card -capable cards that are necessary for applications such as fare cards in which the value stored on the car changes because the holder adds to the card or uses travel value. In this case, reduced security connected to havinUG and Writable Card is low. There are only worms (write once, read many) RFID brands. They are written once by a customer, which is different from reading only that the manufacturer has written once, but neither can be rewritten.
