Many technology enthusiasts have had their eye on Glass, Google’s monocle that looks like something out of Star Trek. But the Internet-connected eyewear doesn’t really pique the interest of Jack Dorsey, chief executive of the mobile payment system Square and a co-founder of Twitter.

“Glasses are very compelling, and I think it’s an amazing technology,” Mr. Dorsey said, “but I just can’t imagine my mom wearing them right now. What is the value of Glass?”

Mr. Dorsey said he fancied devices that wrap around the wrist, like smartwatches or exercise bands, because they felt more natural. The conversation might hint that Square is considering a payment app for a smartwatch, perhaps the watch from Apple that has long been rumored to be in the works.

Mr. Dorsey shared his thoughts last Friday while at a grilled cheese shop in New York to talk about a new feature in Square’s cash-register software for iPads. The new feature allows restaurant owners to speed up the process of placing customized food orders with Square’s cash-register app for iPads, called Register.

With the new software, a restaurant can more easily customize orders. For example, if a customer chooses a grilled cheese sandwich, but wants it with gluten-free bread and extra peppers, the merchant can hit the grilled cheese sandwich button and then individually select the type of bread and extra peppers. In the past, a merchant would have needed to create a separate button in advance for each variation of each sandwich offered — for example, one for a regular grilled cheese sandwich, one for a grilled cheese with wheat bread and one with gluten-free bread and extra peppers.

Mr. Dorsey answered several of our questions about Square and its future. A transcript of the interview follows, edited for length and clarity.

Q.

What’s the message behind the news about the customized food orders?

A.

People have known Square for accepting credit cards. This is a big push we’re making into smaller businesses and brick and mortar, specifically around restaurants. There’s this huge movement around quick-service restaurants all over the country, especially in places like New York, where you order at a counter. Food trucks are often an offshoot of this. These places are doing really creative crafty things and doing them very well.

Q.

When it comes to speeding up food orders for businesses, some of your competitors are enabling the ability for customers to order ahead and pay with an app, then skip the line and grab the food. Are you looking into that capability, too?

A.

That’s definitely something we hear about it and it’s something we’d naturally want to do.

Q.

Last year Square introduced the ability for customers to pay with their face through Square Wallet, its payment app. Are people using that feature a lot, or is it just tech nerds?

A.

We do have early adopters. I don’t want to disparage tech nerds because they’re the ones that spread things like Twitter and Facebook. I think we’ve been happy with the residence of Wallet, but we haven’t been thrilled. A lot of that is due to people understanding how to use it. We have a lot more work to do to surface it.

For those who use it, they love it. For the merchants who receive it, they love it. They get to know their customers as they walk in, what they like, what they might order, and it increases their revenue.

Q.

How has the Starbucks partnership been going? Have you seen an increase in users?

A.

We definitely saw a surge in Wallet. We definitely saw a surge in Register, actually. It really validates the high end. They’re using the same tool that these guys are using, they’re using the same infrastructure. It really levels the playing field for them to compete with each other. It really validates that this is something businesses can trust —this huge company is using it, and I can also build my business on it.

Q.

Have you looked into Google Glass?

A.

I don’t think glasses are the answer. I think it might be a 10-year answer, but not in the next five years. Maybe if they’re in sunglasses or what not.

I think the movement you see around Fitbit, Up and FuelBand, that seems to be the next step in wearable. So something on the wrist that feels natural, almost feels a bit like jewelry.

Glasses are very compelling and I think it’s an amazing technology, but I just can’t imagine my mom wearing them right now. What is the value of Glass?

Q.

Sounds like you have a lot more faith in the rumored iWatch.

A.

(Laughs.) I don’t know, I think there’s a lot going on. The Pebble watch I think is pretty compelling as well.
