when you are transiting you are already inside the 'security zone' so perhaps they don't do another security check?
As someone who flies in and out of Delhi all the time, I can assure you that the security check involves such 'tags'. also procedures for security are standardized across all airports, so it is very unlikely that the process is skipped consistently. I encounter this in the tiniest airports in the country (Trivandrum, Leh) .
Interestingly enough, you can carry your Kindle, phone and/or Ipad in your carry on luggage, but not your laptop. Which doesn't make too much sense, but just the kind of loophole bureaucrats designing security systems come up with.
sorry for the confusion but I meant you can carry your kindle etc inside your carry on bag and don't have to take it out and put it into a tray etc. Your laptop for some reason has to be taken out and put into a separate tray (in Indian airports)
