Recently, small cards labeled as ‘free sample vouchers’ have been appearing frequently on social media and in public spaces—often tucked into delivery packages, stuck on elevator ads, or slipped under doors. These cards typically feature enticing phrases like ‘Claim your free snack bundle!’ or ‘Scan to try for free!’ along with a QR code. However, such ‘sample cards’ may pose serious risks, and consumers should avoid scanning them.Firstly, these QR codes often lead to suspicious links that can automatically download malware onto your phone, stealing personal data such as contacts, photos, and even banking credentials. Secondly, some QR codes redirect users to forms requesting sensitive information like name, phone number, and home address—data that may be used for illegal marketing or outright scams. In more severe cases, scanning the code may force you to follow unknown official accounts or join messaging groups that continuously push fake promotions or investment fraud schemes.Experts warn: Legitimate brands offering free samples typically do so through official apps, e-commerce platforms, or physical stores—not via anonymous, randomly distributed cards. If you encounter such a ‘sample card,’ the safest action is to discard it immediately. Don’t risk your privacy or finances for a seemingly free offer. If you’ve already scanned the code and entered personal details, change your account passwords right away and contact your local anti-fraud center for assistance.
近期，一种名为“试吃卡”的小卡片在社交平台和线下场所频繁出现，常被夹在快递包裹中、贴在电梯广告栏，或塞入门缝。卡片上通常印有诱人字眼，如“免费领取零食大礼包”“扫码0元试吃”等，并附带一个二维码。然而，这类“试吃卡”背后可能暗藏风险，消费者切勿轻易扫码。首先，这些二维码往往指向不明链接，一旦扫描，可能自动下载恶意软件，窃取手机中的个人信息，包括通讯录、照片、银行账户等。其次，部分二维码会引导用户填写姓名、电话、地址等敏感信息，用于非法营销甚至诈骗。更有甚者，扫码后会强制关注某些公众号或加入群聊，后续不断推送虚假促销、投资理财骗局等内容。专家提醒：正规品牌若开展试吃活动，通常通过官方App、电商平台或线下门店进行，不会以匿名卡片形式随机派发。遇到此类“试吃卡”，最安全的做法是直接丢弃，切勿因贪图小利而泄露隐私或造成财产损失。如已扫码并输入信息，应立即修改相关账户密码，并联系反诈中心寻求帮助。
