UK ETA - easy process and very quick response

Not long ago I read a good, informative post here on the forum about the soon to be required ETA for travel to the UK. Today I went ahead and downloaded the UK ETA app and applied since I have an upcoming trip there in the new year. In a matter of minutes after submittal I was approved. The steps in the app were easy to follow. The only thing that confused me was finding the location of the electronic chip in the passport. I had assumed it was located in the front cover under the icon and was unsuccessful at first. It is actually embedded in the top back cover page of my passport. Once approved the ETA is electronically linked to your passport so no printed document or card is necessary.
