The manufacturer has announced that the will soon support "Post-Quantum Cryptography" (PQC) via a firmware update. As quantum computing threatens RSA and ECC, X3 users will simply load a new applet over the air (using GlobalPlatform SCP03), rather than buying new hardware.
The device integrates up to four technologies: X3 Smartcard All In One
: Unlike standard cards, the X3 often utilizes a hybrid chip design (contact and contactless) to support both legacy hardware and modern NFC readers. GlobalPlatform Compliance : Deep papers frequently cite its adherence to GlobalPlatform standards The manufacturer has announced that the will soon
