Thanks for inviting me. First of all, it is necessary to clarify the business needs of the enterprise itself. Some enterprises re-store, some enterprises re-use, and some enterprises pay attention to these archival businesses, depending on how to choose. Second, look at the budget. If you have more budget, you should choose one with more functions. The service is better and relatively expensive. Our company uses Shenzhen Yin Yan Science and Technology Comprehensive Document Management System, because it covers the whole life cycle management of archives, has high cost performance, good service attitude and high product quality, and supports the work of four major features detection, RFID automatic identification, data monitoring and other different links, which is comprehensive and reasonable.
