Products Description
RFID smart cards are secure because any RFID reader cannot read the data from any smart card. The reader application would be required to have the secret keys that are used for encrypting data in the card. The card might block any attempt to access data on the chip if the encryption keys do not match. Similarly, communication between the card and the reader can also be encrypted. The level of security can be decided based on the application where it is used. Data can only be written into the smart card memory by someone who has the authority and knows the keys to the card. Following is a summary of the sequence of events that take place when the card is brought near the reader. ⦁ Energy is transferred to the card that powers the chip inside the card. ⦁ Clock signals are transferred from reader to card ⦁ Data transferred from reader to card ⦁ Data transferred from card to reader.
Product Process
Access control and security systems can use electronic tags, and one card can be used for multiple purposes, such as work permits, access permits, parking permits, hotel accommodation permits, and even travel passports. The use of electronic tags can effectively identify personnel, carry out security management and efficient charging, simplify entry and exit procedures, improve work efficiency, and effectively carry out security protection. The system will automatically identify the identity when a person enters and exits, and an alarm will be issued when an illegal intrusion occurs.
RFID Smart cards have many applications not only in the financial and payment industry, but also in gyms, restaurants, libraries, playgrounds, identity management, access control, logistics, healthcare, transportation, parking systems, mobile communications, and more. As smart card applications have grown, smart card technology has evolved from simple magnetic stripe cards to RFID and NFC cards. Different types of smart cards are preferred in different applications. A smart card contains an embedded chip (integrated circuit), which allows it to store data and/or house a programmable microcontroller. A smart card system typically includes a card and a card reader. The electrical specification for smart cards is based on the ISO 7816 specification. This includes standardizing the size and location of the different contacts in the smart card.
