Well recently i made a trip to my dad's house in salem. i made a visit to my friend's house and on my way back i was astonished to see the conductor giving me an printout for a ticket. Actually i along with my friends were thinking on it a few months back. i was actually very glad to see that to be implemented in a remote route infact it wasnt even implemented in chennai.
The same day i went to have my dinner in a hotel named "ananda bhavan". I saw a glass screen that actually displayed flashing texts. it had a single handle which was abt the dimension 75*7*5cms. It had no other connections and no wire connections inside the glass... a cool technology display...
