Mifare Ultralight ID Cards

An Ultralight NXP chip card is a type of contactless smart card that uses passive radio frequency identification (RFID) technology to store and transmit data, and has a typical operating distance of up to 10cm, operating on a 13.56 MHz frequency. It is commonly used for low-level security access control, such as building entry or travel passes. Ultralight chip cards are strong and durable and have a small, embedded chip that can be contactlessly read by suitable card readers. However, their limited memory capacity means they are not suitable for storing large amounts of data or highly sensitive information.
