.. yk5-physical-attributes.rst .. _yk5-attributes-label: =================== Physical Attributes =================== The serial number is printed on the back of every YubiKey in the YubiKey 5 Series, YubiKey 5 FIPS Series, YubiKey 5 CSPN Series, and YubiKey Bio Series. The 2D barcode (Data Matrix code) of the serial number is also printed on the back of every YubiKey in the 5 Series (as well as on the FIPS and CSPN) except on the 5C Nano form factor, which is too small to accommodate the 2D barcode. In addition, all of the keys in the YubiKey 5 FIPS Series have the acronym “FIPS” underneath the Data Matrix code on the back, along with “v5” running up the left side of the Data Matrix code, except on the YubiKey 5C Nano, which has it on the right. All current YubiKeys have been `IP68-rated `_ under the IEC standard 60529. YubiKey 5 NFC ============== ..
