Here's your money briefing for Tuesday, October 15th.

I'm J. R. Whelan for the Wall Street Journal.

In the era of swiping and tapping, your signature has become virtually meaningless.

But the rules for putting your name on the dotted line aren't always clear.

Sometimes you're signing, sometimes you're not.

So some businesses have more updated point of sale systems.

You might be used to seeing those toast or square pads where you can make your purchase on.

In those types of things, businesses can

actually choose to not have the signature portion as part of a transaction.

We'll talk to Wall Street Journal Personal Finance reporter O'ian Adad a doion after the break. This podcast is brought to you by CME Group, the world's leading derivatives marketplace, offering the widest range of global benchmark products across all major asset classes.

CME Group, where risk meets opportunity. For centuries someone's signature was like a final official stamp on things like contracts and documents, but your signature may now be obsolete.

Wall Street Journal personal finance reporter Oion Adadoyan joins me.

Oion, when did signatures become meaningless?

Well, signatures at least in the day-to-day sense for things like shopping at the grocery store or buying a drink are not as relevant today and they haven't been relevant at least in the last couple decades actually.

Once upon a time merchants used to have to collect your card information manually

and imprint those numbers onto a piece of carbon paper when you made a transaction.

I'm old enough to remember that.

Oh you remember that?
