What security checks should be applied to cheques or vouchers?

When processing cheques or vouchers, it's essential to implement several security checks, including verifying the authenticity of signatures and the presence of watermarks or security features. Ensure that the cheque or voucher is not post-dated or stale-dated, and confirm that the amounts match between the written and numeric sections. Additionally, utilize a robust system to track and manage cheque or voucher issuance and redemption to prevent fraud and ensure accountability. Regular audits and employee training on recognizing fraudulent instruments can further enhance security.
