正确说法

• 在发生劳动争议时，劳动者应尽量保留工资单、考勤记录和劳动合同等书面凭证，以便在仲裁或诉讼中举证维权。(When a labour dispute arises, workers should preserve written evidence such as wage slips, attendance records, and employment contracts, so they can produce proof in arbitration or litigation to protect their rights.)
• 电子凭证与纸质凭证在法律效力上已趋于等同，但企业在内部审计时仍需确保电子档案系统符合相关安全存储规范。(Electronic vouchers and paper documents have become increasingly equivalent in legal effect, but enterprises still need to ensure their electronic archive systems comply with relevant secure storage standards during internal audits.)

错误说法

• 凭证 is formal and official — do not use it casually for informal 'proof' between friends; 凭证 implies a document or object, not just an argument; for non-documentary proof/evidence, use 证明 or 依据
