difference between Verification and Validation

[Maggie]

Hi,guys

Here I made two sentense for those two terms. Actually,I am trying to make sentense to understand how to use them. However,I couldn't figure out sentences of verification and validation. So I simply made 'verify' for verb and 'valid' for adjective. Could you give me some examples for 'verification and validation'? Thanks in advance.

1.verify

I needed to verify some wireless products if all of the functions can work.

2.valid

You can use some functions of this software if they are valid. However,if the functions are invalid,that means you have no right to use it.

Greeting!

Maggie

His driver's license is valid. It has not expired, and he can still use it.

The policeman punched her driver's license number into the computer to see if it was still valid.

That is not a valid argument. It has no relevance to the situation.

The fact-checker at the newspaper verified the facts in the reporter's article.

The police could not verify the man's name. (That is, they couldn't find out if it was really his name or not.)

The man's story was not verified. (Nobody found the story to true.)

The man's story was verified. (They checked and found out it was true.)

The policeman is verifying whether the driver's license is valid. (He is trying to find out whether the license is still good to use.)

Remember that the word "verify" comes from a Latin word for "truth", so if you verify something, you find out whether it's true or not. So you get:

We verified his story. (We determined that it was true.)

The word "validate" comes from a Latin word meaning "to be strong", but the English word can involve value:

The store clerk validated my parking stub.
In some American cities, people don't have to pay for parking if they have gone shopping in one of the stores in the area. Usually the system is that when you buy something at a store, you give your ticket from the parking lot to the clerk, and she validates it with a rubber stamp. Now the ticket is valid. It has value at the parking lot, and when you present it to the attendant, you will not have to pay anything to park. If the ticked has not been stamped, -- i.e., validated -- it has no value, and you will have to pay.

Nowadays, banks and credit card companies ask you to validate your credit card before using it. When it first comes in the mail, you cannot use it. If you try to buy something with it, it won't work. First you have to validate the card by phoning a certain number and verifying some information (stating that the information is correct). After you have done that, the credit card is valid. It has value, and it will work when you try to use it.

Hi,Jamie

First of all,I appreciate your help very much. I have one more question.Here,you wrote that 'Nowadays, banks and credit card companies ask you to validate your credit card before using it.' May I say 'Nowadays, banks and credit card companies ask you to verify your credit card before using it'? I still get confused for these two terms. Thanks in advance.

BTW,I hope I don't take unnecessary pains to study an insignificant or insoluble problem for this kind of question.

Greetings!

Maggie^^

When you validate a credit card, you put your credit into operation. Before you validate the card, it's useless, and if you try to buy something with it, the computer will have no record of it existing. After you validate the card, the card has become valid, and when you try to buy something with it, the computer will recognize it.

When you go to buy something with this validated credit card, and the clerk does not know you, they need to verify that it is your card. For this, they check your driver's license or identification card, and if you are the person in the picture, they have verified that it's your card. Then they have to verify whether the card is valid -- whether it is functional and you can make purchases with it. This is done by swiping the card through the reader. If the computer gives the message that the card is okay, has been validated, is functional, it has been verified.

Validate and verify don't mean the same thing, so they are not interchangeable.
