Tech : Some Information about Payment Banks in India. What is Payment Banks and it's function?
Payments Banks:
This is a new model of bank in India incited by former RBI (Reserve bank of India ) governor Raghuram Rajan (2013-2016) in 2014.
These banks can accept a deposit upto ₹100,000 ($ 1500 around) per customer.
They can't issue loans and credit cards but can operate savings and current accounts. Also they can give services like ATM Cards, Debit Cards, Online Banking, Mobile Banking, UPI Banking ( Unified Payment Interface, This service launched by RBI), Aadhaar Banking (banking system use biometric authentication for payment no need any password or pin)
Requirement for Payments Banks :
The minimum capital requirement is ₹100 crore ($ 15m). Foreign share holding will be allowed in these banks as per rules of FDI ( foreign direct investment ) in the private banks in India.
These banks must use "Payments bank " term in their name. 70% of its deposited amount should be invest in the government bond ( India ) and 25% of its branches must be in the unbanked rural area.
Launched Payments banks :
Currently "Airtel Payments bank " has been launched on 15th January 2017, India Post has been launched on 30th january 2017 and "Paytm Payments bank" will be launched on the 1st week of February 2017.

SPIRITUAL : SILENCE IS THE MOST POWERFUL WORD IN WORLD
What is the powerful things in the world ?
money? people? No.
#Silence as It has no boundary. So don't think about people or money just about your love and passion. People and money can't give you peace but you can give it to you. It is not matter what people say about you. It is matter what you say about yourself and think about yourself.
You see people are selling each other because other are doing so.
Do you want to be like that people then you can do what they are doing. But if you don't want that do what you think and like.
some people may have bound to do this thing but why should you come in this bound? why would you see world by the other people mirror but your own mirror. ... It isn't that physical work is so much effective but #Silence .
Do you have seen Silence sea? Do you know how dangerous is a silence sea? You can't judge anything by seen a silence sea. If your mind go to the silence position think what mind can do.Is anything impossible for this mind? Silence can can create infinite possibility in the mind. Silence is the more effective than anything in the leaving creature.
What is the difference between men and other animals? Nothing but Silence. For this men are unstoppable.

Spritual: Some times I become Thoughtless
Sometimes I become thoughtless and speechless, ask myself what do you want? My mind says don't know. Everything is within me so I don't need anything. Then I ask why are you searching here and there? In reply it says that to increase the awareness that Everything is within me. So why are you frustrated and fear about your job or work? Your job and work can't give anything to you except you. So don't fear do what you want.
Don't greed about anything as you can't get anything. You get what you are. So do what you love and what you think. Never mind what people say or think about you. You came in this world to search your love. For searching love don't afraid about physical pain of your body. In the physical pain of your body you will have your freedom and freedom is the ultimate goal of your life. Anything isn't matter to you expect freedom. In love there may be physical pain but don't give up your love. In the World you come here to search your love. See everything but choose what you love. Think about the people whom love you most. Do the work what you love.
Don't fear to lose. You are doing what you love. Don't think about result of the work as you are doing what you love.
Thank you. Please feel free to comment.

Tech : BHIM App lunched by Narendra Modi, Best UPI App Review
1 #BHiM app is one the best upi app. It also very fast and transaction time is less than one sec. 9/10
2 Lotza by Federal bank
Lotza is also very fast app also another feature of this app you can use many upi address and many account at a time. 9/10
Lotza is also very fast app also another feature of this app you can use many upi address and many account at a time. 9/10
3 Sbi pay this app is very very slow. If you wrongly enter your mobile number you can't change it by again uninstaling it.
3/10
3/10
4 Axis pay this is axis bank upi app. this app is also not so bad. Some people are facing problem that scan option is not working on their phone. This is not as so fast as first two app. 6/10
5 PhonePe this upi app is also good but one main concern is that you can't transfer your money from phonepe to another upi app. Transaction failure rate is very much. 8/10.
6 other upi app are #pockets and hdfc upi etc . they also good
.
