Key verification of replaceable fuel cartridges

A method of verifying, for use, a hydrogen fuel canister, the method comprising:

• obtaining a value for a unique identifier element (UIE) associated with a fuel canister by querying a database;
• placing an electronic matrix (500) on a canister into a e-matrix reader (600);
• measuring a value for the electronic matrix via the e-matrix reader of the on or off state of one or more array elements in said electronic matrix;
• comparing the value obtain via the e-matrix reader with the value from the database associated with the UIE;
• and,
• using the comparison to authenticate or not authenticate the canister.

A method of verifying, for use, a hydrogen fuel canister, the method comprising:

• connecting a cartridge with a host device obtaining a value for a unique identifier element (UIE) associated with a fuel canister by querying a database;
• placing a plurality of armatures (703A-703N) on a fuel canister into a an of armature matrix (700) on a host device;
• measuring a value for the induce voltage;
• comparing the value measured with the value obtained from the database associated with the UIE;
• and,
• using the comparison to authenticate or not authenticate the fuel canister.

A method of verifying, for use, a hydrogen fuel canister, the method comprising:

• connecting a cartridge with a host device obtaining a value for a unique identifier element (UIE) associated with a fuel canister by querying a database;
• placing a plurality of illumination sources (805A-N) on a fuel canister into guides (802) of a photon measurement matrix (800) on a host device;
• measuring illumination values via detectors (810);
• comparing the value measured with the value obtained from the database associated with the UIE;
• and,
• using the comparison to authenticate or not authenticate the fuel canister.
