An electronic payment system which emulates the payments relying on classical cheques is presented. Its main features are a high computational efficiency and low storage requirements for the tamper resistant smart card implementing the purse of the user. This is achieved using a counter-based solution in combination with public-key certificates that represent the electronic cheques. To simplify both the withdrawal and the deposit stage we renounce to provide the untraceability feature. Our payment system is built around the Guillou-Quisquater identification/signature scheme in an RSA-group.
