TDAService is an embedded utility application designed specifically for use with the TDAService SDK, facilitating the reading of Thai national ID cards. This application operates in the background and requires a primary application developed from the TDAService SDK to function. It supports various smart card readers, including Bluetooth and USB models, and is compatible with Android devices running version 4.0 and above. Users are advised that without the main application, TDAService will not operate independently.

The software development kit (SDK) includes essential components such as sample applications and source code, enabling developers to create applications that can effectively read and extract 24 types of data from Thai ID cards. This includes personal identification numbers, names in Thai and English, addresses, and photographs. The TDAService is particularly suitable for government agencies, banks, and private sectors that require ID verification. However, it is important to note that the SDK has ended its technical support as of December 31, 2019, and developers are encouraged to transition to newer development kits for future projects.
