Single-Use Credit Card Numbers for Better Privacy

Online shopping is  very convenient since it saves us a lot of time and allows us to find the best prices without leaving our homes. Getting the things we want is as easy as putting the item in our virtual cart and checking out. But at checkout, do you slightly hesitate when having to enter your credit card number? I know I do, and it’s completely normal as you are worried that your credit card number is going to fall into the wrong hands.

If you regularly shop online, you are going to love Privacy. What it does is generate a one-time credit card number for your online shopping that will only be valid for one purchase. This will repeat itself every time you buy something online. This way you will never have to give your real credit card number, and as a result it reduces the chances of you falling victim to identity theft. You will, though, have to give your information to Privacy to complete your purchases.


Signing up is very easy. You start by filling out a short form. You are asked to enter your Email, Password, Address, Name, and birthdate. The last step would be to connect the bank account you will be using, and Privacy works with banks such as Citibank, Chase, Bank of America, and Wells Fargo.

Your login information is transferred through a safe TLS (SSL) connection. Privacy also uses 256-bit encryption to keep your information secure while transfering your login details.

You will also be asked to install the Privacy Chrome extension to make your online shopping a lot easier. For now there is only an extension for Chrome and Firefox, but Support for Safari and Internet Explorer are coming soon.

At checkout you should see a small Privacy icon right beside the credit card form, and when you click on it Privacy will automatically create a new virtual credit card particularly for the site you are shopping on.


You get to choose from what account you want the money to be withdrawn from, making it comparable to a debit card. You can either use Privacy’s mobile app or the web app. To cancel cards from there, pause them or set charge limits that go from $1,000 per day and $2,000 per month.

You can also have a credit card number for a certain service. For example, you can create an alternative credit card number for only your Hulu subscription. That number can only be used for that and nothing else.

You can also easily stop those annoying 30-day free trials that make you give your information to try their service. This way, if you forget to cancel it on time, you can just eliminate that Privacy number you had for it.

It’s up to us to keep our information safe, and Privacy is a tool that will help us with that. If you have used PayPal, you won’t have a hard time getting used to Privacy.
