CodePudding user response:

Id card machine manufacturers with the SDK, very simple function to read id information, I used in China,

As for the rest of the registration of software, which is a database operation, do not need too much technology content, in addition, you need to id information report to the department of XX, these operations have corresponding interface,

CodePudding user response:

Yes, card reader usually have a variety of development tools such as the interface to the SDK and examples, as for the registration part depends on the actual demand, completely is not difficult, you can develop the keyboard and mouse input part, card reader are OK when you have added in the future

CodePudding user response:

As long as you learn to operate the database can make, you can learn ADO + Access

Advantage is that can be very easy to upgrade to ADO + is essentially, both to realize single machine trial, can also be upgraded to a powerful online

As for DataSnap and JSON, you can add in the future, using ADO + Access can also be easily upgraded
