The concept of Match-on-Card (MoC) consists of a smart card which receives an applicant's candidate template T to be compared with the stored reference template Tref by processing the complete matching algorithm during a biometric authentication request. The smart card will then output whether this comparison is positive or not. The main argument against MoC-enabled smart cards is that it opens the way for YesCard (i.e. an attack path previously seen in Banking, a card always returning \"Yes\"). The threat regarding Biometrics is not only YesCard, but also NoCard as the authors will see in this paper.
