Ecrf system is a software and hardware platform with the function of generating EDC. If ecrf is compared to "electronic cash", then EDC system is equivalent to Alipay platform.

Of course, generating ecrf is only a small part of the powerful function of EDC system, just as Alipay is not just an electronic payment business.

China's Institute for Drug Control also requires the basic functions of ecrf system, including ecrf construction, data storage and audit trail, automatic verification, data query management, source data verification and confirmation, electronic signature, database locking, data storage and export, etc.
