Description

technical field [0001] The invention belongs to the field of biological feature collection, and in particular relates to a palmprint information collection device. Background technique [0002] With the increasing diversification of functions of integrated circuits, devices that used to be special products, or devices that were not available at all, have gradually become popular. For example, a palmprint scanner, similar to a fingerprint scanner, is an example. In the past, the palmprint recognition system, which was rare or never even heard of in the traditional consumer product market, has become popular among ordinary users who are concerned about access control and identification due to the emergence of integrated circuit palmprint scanners. Increasingly popular; the application field of palmprint recognition system is no longer limited to government and security personnel. These devices are used to ensure that only authorized users have access to a computer system or ...
