What does data capture-only capability lack?

The data capture-only capability primarily involves gathering and recording transaction-related information without the ability to execute further actions that require additional functionalities. While it is effective for collecting data, it does not include the process of online authorization, which is essential for verifying a transaction in real-time before it is completed. Online authorization allows for the confirmation that sufficient funds are available and that the transaction should proceed.

In contrast, other functionalities mentioned, such as data analysis, storage for transaction receipts, and data encryption, can be present or managed separately from the immediate data capture process. Data analysis can be performed once the data is collected, receipts can be stored for compliance purposes, and data encryption, which secures sensitive information, may be implemented independently. Each of these capabilities enhances data management and security, but they are not inherently part of the fundamental data capture function, making online authorization a distinct service that data capture-only systems do not provide.
