The Difference Between MIFARE 4K and Mifare 1K

You may come across Mifare 4K and Mifare 1K cards. However, how different are they? Which one to choose? The main difference is in the memory capacity of the two cards. The Mifare 4K has a storage capacity of 4KB, while Mifare 1K has a storage capacity of 1 KB. As such, storing more information on the Mifare 4K card is possible.

The applications between the two cards can also differ, with the Mifare 1K cards mostly being used for basic applications such as access control systems, loyalty programs, and ticketing systems.

The Mifare 4K cards can have more complicated applications because of their memory size. Such applications include public transport systems, multiple application systems, and more.

As for compatibility, these cards are the same. Since they operate at 13.56MHz and use the same Mifare technology, they are all compatible with the same card readers or systems.
