Not for your use.
The idea is to speed up the immigration and I, for one, applaud the progress. It made a huge difference the last time I exited Bangkok. If I want to track my travel I can do it without the need for stamps in my passport. Same is true for Thais, traveling to the UK, they are not stamped out but their travel record can be obtained from airline records - these details are equired for subsequent UK visa applications.
