RFID is actually a general term for radio frequency technology systems. An RFID card is a radio frequency card. Now let's talk about what is a radio frequency card. The so-called radio frequency card is actually a chip card with frequency induction. The card usually contains an IC or ID chip. As for the cards currently appearing on the market, according to the frequency of transmission, it can be generally divided into: low frequency card (ie 125K Hz), high frequency card (ie 13.56M Hz), ultra high frequency card (915M Hz).
There are now many RFID Labels, such as I CODE SLI (1K) RFID Smart Label and I Code SLI-S On Metal RFID Label
So what is the difference between an IC card and an ID card? Most of the membership cards seen in life are actually IC cards. Like a bus card, an access card, etc. can be an IC card or an ID card. The difference between IC and ID card is that one of them belongs to low frequency and one belongs to high frequency.
In general, IC cards have stored value and security functions, and ID cards do not have this function.
RFID cards are divided according to other methods, and then can be divided into standard cards and special-shaped cards. The so-called standard card is a common PVC card, and a standard-sized RFID card can be called a special-shaped card.
The above mentioned high-frequency IC card and low-frequency ID card, in fact, there is a card called ultra-high frequency card, such as G2 white card, electronic tags are UHF. UHF cards are now widely used in production companies and some special facilities. These UHF cards are relatively rare in life. This UHF card has a large memory and can store more data. This is obviously different from IC and ID cards.
