Abstract
Systems, methods, apparatus, and computer readable media are provided for disposable component authentication with respect to a biological fluid processing device instrument. An example instrument authentication system includes a computer facilitating configuration and operation of the biological fluid processing instrument using a disposable component. A first interface is provided by the computer and is used by a service technician to configure the biological fluid processing instrument for a number of disposable components and to provide a service technician with a validation code. A key generator is to accept the validation code from the service technician and generate an authentication key in response to the entered validation code. A second interface is provided by the computer, the second interface prompting the service technician to enter an authentication key, wherein the authentication key authorizes use of a certain number of disposable components for the biological fluid processing instrument.
