Metal cards already stand out, but individuals who are looking to upgrade theirs can use NFC (Near Field Communication) smart cards. Because it is a user-interactive technology with various use cases, employing NFC can make the cards more functional. 

However, one may not know what NFC chip to get when one decides to install it. The following information delves into the different types of NFC chips. 

How much memory is required?

Each NFC chip has various memory sizes. Understanding this is essential, especially for those who need to put a lot of information on their cards. Some individuals might prefer a smaller memory size. For example, for users who require chips for simple daily tasks, the NTAG213 is an ideal option. It has a memory of 144 bytes and is relatively cheap.

On the other hand, larger size means they can transfer more information. The NTAG216 contains 888 bytes, making it ideal for people seeking a much higher capacity and for metal business cards with complete V-Card data. 


In general, NFC Chips are rewriteable, making it easier to add or edit information. Password protection is also supported by some chips, implying that a password-protected tag or card can only be reprogrammed by somebody who knows the passcode. This is an essential feature if users want to leave their tags or card in public spaces. 

Moreover, those seeking to up their game in security might find it helpful to consider NFC chips that have encryption, such as MIFARE Ultralight or MIFARE Plus, to prevent other people from obtaining access to the contents of the chip. Encryption also helps prevent identity fraud.
