As a foreigner visiting India with the demonetisation is also not the most pleasant experience, I had landed on the day that happened. A lot of places luckily accepted credit cards, though in a few cases the authorisation failed (which can also occur at the ATM's, so be careful when queuing) and they don't always have the best infrastructure either (http://imgur.com/a/iJDfw). PayTM isn't an alternative as a foreigner, since you can only charge your account with Indian issued debit or credit cards.
