Well we all have faced the problems due to demonetisation but the thing which helped us a lot was paytm. Yes paytm it was a digital way to transfer money or do the transactions. It is a app which can be used to recharge you mobile no., dth, can be used at shops, gas buying, petrol pumps , tolls, taxis, online shopping and even now you have an option for challan too. It is very nice of doing transactions as you need to carry cash simply scan, write and pay. No problem no hassle.
Well every coin has two sides and even paytm has I know it is very good but still it is used by only very few people not a major part. Many are there who even dont know what is paytm. It requires and active internet connection every time for the transfer. Lets think everything is digital and wherever you go you need to pay using paytm and think you went to an restaurant and had all food abd when payment time comes your data pack is over or the speed is slow or the biggest problem if you battery dies.
Well its a cool app with great concept but still there is some scope of improvement.
