Physical Attributes

The serial number and its 2D barcode (QR code) is printed on the back of every key in the YubiKey 5 FIPS Series except the YubiKey 5C Nano, which is too small to accommodate the 2D barcode.

All of the keys in this series have the acronym “FIPS” underneath the QR code on the back, along with “v5” running up the left side of the QR code, except on the YubiKey 5C Nano, where it runs down the right side.
