If u want to pay using your paypal account.
1) Go to Entropay.com
2) Create an account and link your Credit/Debit card there (any Indian bank card with Visa Logo works).
3) Create a Virtual Credit Card on that site.
4) Link your Paypal account with your Virtual Credit Card.
5) Done.
There exists a secure workaround. Entropay allows you to create a Virtual Credit Card. The advantages are simple.
1) You pay using a Virtual Credit Card so Card theft is out of the question.
2) The balance on your card is no way linked to your Real life bank account so your account is hidden and hence secured.
3) You charge your card only if u wanna pay for something. Basically, Imagine If you want to buy something for 30$, then add 30$ to your virtual credit card balance and then use that virtual credit card to buy. So even If it is hacked, there is no loss of money.
4) The VCC (Virtual credit card) can be destroyed with one click. And creating another one is free, basically create as many as u want ^^.
PS: I myself have an account there. Its safe and secure, but naturally, no services are free and there is a charge per transaction. Read all the rules before making an account. If your account stays inactive for a specified period of time (around 4-6 months I think), certain amount is deducted from your virtual balance.
