Elfqrin Discard & 8 Other Online Credit Card Number Gernerators

Don’t worry, this post isn’t about fraudulent activity! Credit card number generators like Elfqrin discard won’t actually produce a credit card number linked to an account - and even if it did, you still would need various other proofs that it is a real card in order to purchase anything such as a CSC number, a name and an expiry date.

Instead, credit card number generators are used when a website requests the number of your credit card, but you don’t want to give a real one out. Some websites can use this to verify that you are an adult.

They can also be used by programmers who are testing e-commerce websites, online applications and software. To test, you need lots of data. Fake, but valid data is best - and that is what these websites like Elfqrin discard provide.

They use an algorithm that will come up with a valid 16 digit number for a credit card. Read on to find out more.

What constitutes a valid credit card number?

The credit card number - also known as the primary account number - has several fields, each with its own meaning.

The number consists of a 6 digit issuer identification number (IIN), followed by an individual account identification number and a single digit checksum.

The first digit of the IIN is known as the MII or major industry identifier. If this digit is a 9, then the next 3 digits will be the country code. The first 6 digits identify who you bank with.

Mod 10 Algorithm

In order for the generated numbers to be considered valid, they have to satisfy testing by the Mod 10 algorithm, also known as the Luhn Formula. It is a public domain algorithm developed by an IBM research scientist in the 1950s. It is not intended to be a cryptographic ally secure function. Instead, what the Mod 10 simply does is protect against accidental errors when keying in a card number - it is not designed to prevent malicious attacks. Websites use the Mod 10 to easily distinguish valid numbers from mis-typed numbers.

How does it work?

It is actually quite a simple, but ingenious algorithm. If you are in to programming, you could certainly make a credit card generator yourself. Here is the Mod 10 for the number “38520000023237".

• The last digit 7 is known as the “check digit”.
• You then take the rest of the sequence: 38520000023237
• Starting from the right hand side of this, you double every other digit: 6,8,10,2,0,0,0,0,0,2,6,2,6
• You then sum the digits (10 = 1 + 0 = 1)
• 6+8+1+2+0+0+0+0+0+2+6+2+6 = 33
• Multiply the result of this by 9
• 33*9 = 297
• If the last digit is 7, then this is considered a valid sequence of numbers.
• The last digit of the final product must equal the checking product.watch anime

Will these work for the Netflix free trial?

People often try to use generated credit card numbers in order to get free trials of products. This might work for smaller websites, or badly run businesses. It’s not likely to work for the likes of Netflix however.

Here’s why. As well as asking for a card number, Netflix also tries to make a small 1 dollar transaction on the card to see if the card works. The 1 dollar is returned to the card afterwards, it’s just a simple process to see if the card is real or made by a generator. Unfortunately any number made by the following websites isn’t going to be able to pay out that dollar!

Discard

Elfqrin discard, also known as “Elf Qrin’s Cyber Lab” is probably one of the oldest running credit card number generators on the internet. It really feels like an old-school 1990s website too. It still works great though!

creditcard-generator.com

This card number generator is more useful than most. Here you can specify the number of cards you want, the brand of card, formatting with spaces or dashes and the year type. This easily beats elfqrin discard.

Tools4noobs have recently updated the look of their site by using Bootstrap frond end developing. The site looks slick, and is much nicer to browse than Elfqrin Discard. Another nice thing is that you won’t find any annoying advertisements here.
