AI seal control,
clearly explained.

Shenzhen Chengzhang Technology Co., Ltd. builds AI self-service seal robots and intelligent seal-control systems for banks, financial institutions, central SOEs and large enterprise groups.

It is an enclosed device that prints a document, compares it with the approved version, applies a physical seal and scans the result. The operator does not touch the seal.

Organizations with paper contracts, physical seals and multiple sealing locations: bank head offices, credit centers, branches, shared service centers, group headquarters and subsidiaries.

E-signature signs electronic files. The seal robot controls a physical seal on paper documents. They solve different problems and can be used together.

Standard interfaces are available. The exact fields, task flow and integration effort depend on the customer systems and project scope.

Seven Xinchuang compatibility certificates are published, covering UnionTech, Dameng, Hailiang, MogDB, Baolande, Haitai and Qianxin. Each project should verify versions and the adaptation checklist.

Offline sealing is supported. The practical scope depends on local deployment, task synchronization and the customer network policy.

The physical seal stays inside the device. Every task is authorized and recorded, and the device supports return verification and exception monitoring.

It is a proof-of-concept (POC) sample comparison result for a specific document set and scenario. It is not a performance guarantee for every production environment.

Customer names, logos, photos and operating data require written authorization. Public pages keep only the anonymized industry, scenario, solution and stage.

Use the contact page or the selection assessment. A useful first step is to bring one high-frequency sealing scenario and the current system landscape.

The site publishes 13 patent certificates and 9 qualification/product certificates, plus 7 Xinchuang compatibility certificates. The company material also references 25+ patents and software copyrights.

Traditional custody relies on dedicated staff, manual approval and manual supervision. The seal robot keeps the seal inside the device and links permissions, tasks, document comparison, automatic sealing and records into one controlled process, reducing manual contact and register gaps.

The task, applicant, document, seal position, time and process video can form a record for later review. The public material describes an application–approval–sealing–evidence loop; the exact fields and retention period depend on the project configuration.

Full-document machine-vision comparison checks content and layout differences. Public material mentions alerts for replaced pages, blank amounts, masking and layout substitution. The published 99.9% POC figure has a specific sample and scenario scope and is not a guarantee for every deployment.

The public selection checklist mentions multi-seal positions and multiple-seal management. The exact number of positions, seal types and configuration must be confirmed against the device model and project plan.

Common locations include head-office offices, lending centers or credit factories, branches, shared service centers, group headquarters and subsidiaries. Placement depends on where sealing happens, network conditions, seal permissions and site space.

The solution supports central management at headquarters with distributed execution at branches. A group can aggregate sealing activity into one platform or manage it by legal entity or region; the architecture depends on the organization, policies and systems.

The public service page lists support intake, remote diagnosis, on-site support, warranty and spare-parts support. Response times, warranty scope and spare-parts policy follow the contract and service terms.

Public articles describe Qingxiu Technology as a joint venture established by Chengzhang Technology and the University of Science and Technology of China (USTC), participating in the joint operation of the China–ASEAN Financial AI Service Sharing Network (CAFAIN). Equity and affiliation details should be confirmed against official disclosures and business registration.
