A solution to the problem of bounced checks 1 A solution to the problem of bounced checks Tunichèque was created to solve a major problem: bad checks. For years, merchants, professionals, and institutions have suffered from late payments, disputes, and costly legal proceedings. This system modernizes checks by making them verifiable and secure. 2 Instant verification and QR code Each Tunichèque check is equipped with a QR code. By scanning it, the beneficiary can verify in real time whether the drawer's account contains the necessary funds. This step eliminates the risk of accepting a bad check and strengthens confidence in the transaction. 3 Funds reservation: a payment guarantee The beneficiary can choose to reserve the amount of the check. This means that the funds are blocked in the customer's account until cashing. This feature is crucial for large retailers, service providers, and institutions that want to avoid unpleasant surprises.
