The MIFARE Ultralight® AES IC delivers a new level of trust for limited-use tickets and key cards by supporting AES cryptographic authentication. Designed as a secure, contactless replacement for traditional paper tickets, mag-stripe, barcode, and QR code-based systems, the IC gives solution providers a more convenient, secure way to issue single-trip and multi-use transit tickets, event tickets, access passes, loyalty cards. Further, in hospitality, it gives guests secure access to hotel rooms and other hotel facilities, including spas, gyms, and parking garages.

• Security 
  • Protected data access based on AES authentication with 128-bit key length and optional Command Counter to limit negative authentication attempts
