After downloading the pdf of the e-aadhar from the website (www.uidai.gov.in), when you open the file, the screen prompts a window asking for a password. It is so, because the file is password-protected, since it contains personal details. The password here is the Postal Index Number (PIN) code of your locality. After you enter it, the file unlocks and you can view your e-aadhar.
Venmo is a way to send money from person to person through the web. Like PayPal (which owns Venmo), the Internet and mobile device-linked service connects to your major U.S.-based bank account or debit card, so it can pull funds from and make deposits into your checking or savings accounts.
Keep yourself safe. Venmo is designed for payments between friends and people who trust each other. Avoid payments to people you don't know, especially if it involves a sale for goods and services (like event tickets and Craigslist items).
