A fingerprint is one of the unique biological characteristics of each person, with a high degree of sensitivity. However, in recent years, more and more spending places are starting to collect fingerprint information. This behavior is making consumers feel uncomfortable. Recently, a Chinese tourist complained that when he bought a discounted ticket at the Big Hippo Water World in Baiyun District, South China's Guangzhou, he was told that he needed to verify his fingerprints before entering the park. He questioned the necessity of fingerprints and expressed concern that the highly sensitive fingerprint information might be leaked if it was collected. People in the park explained that collecting fingerprints is aimed at preventing ticket fraud. They contended that it makes it easier for visitors to re-enter the park after a temporary leave. Some experts said that fingerprints are personal information with high degrees of privacy. Consumers should pay attention to protect their privacy. They have the right to refuse unreasonable information collection.
