"Eye, I need you to remember something from now on."

"What is it, Master Ars Barca?

"Eye can calculate gold, right? And you don't have a problem identifying people's faces?

"Yes, calculations are definitely doable. However, a person's face has an indeterminate element. It's definitely not immutable, so you can't deny the possibility of making a mistake."

"I see. So how about fingerprints? The pattern on a person's finger should be different for each individual. I think remembering this reduces the chances of people making mistakes. And then you are. I've heard that triangles that connect eyes to nose positions also vary from person to person. Can't we use that for personal identification?

"That's an identification in relation to the structure of the fingerprint and the face. We need to verify if that information is correct. Validation takes time"

"Okay. Verify it."

I put holy marks in my eye's body.

And it is well known that it is forbidden to take away the engraved of the sacred marks at will.

After I did that, I decided to add more eyeseries.

Because there were uses that Kyle wanted to mass produce and use apart from those used for the Reed family.

That's how I ask the new eye I created.

It was about whether I could do the work I asked for.

At this time, the most important way to identify individuals was to identify them.

Eye had normally begun to learn to work at Charlotte Castle until now, so I thought it would be okay, but still, apparently there was an indeterminate element in the identification of the individual's face, etc.

Well, is that right?

People can get hurt.

For example, if the skin is damaged in a wide area due to a fire or the like, the appearance will be very different before and after that.

In doing so, I may not be able to identify the same person with my face alone.

So I decided to teach Eye about fingerprints and facial authentication.

I also tried to suggest if I could not do voiceprint or handwriting appraisals that I later remembered.

If these things can be achieved, the eye will be able to identify the individual with certainty.

That way I might be able to get the job I'm looking for.

"What kind of work does Master Ars Barca want from Eye?

"You listened very carefully. Banking is what I want Eye to do."

"Bank, is it? I remember Master Ars Barca owns Barca Bank. Is it the Barca Bank?"

"That's right. That's for sure, Eye. What I want Eye to do is manage the most important entrance and exit payments for his work at the bank."

Fingerprints, facial authentication, handwriting appraisal for voiceprint appraisal, etc.

If you can exercise them to reliably determine their existence, there was a job I wanted Eye to do.

That was the management of the money at Barca Bank.

I have a lot of work at Barca Bank.

One is money-making using the Tallow series of smelting silver.

With the power of a white dog-man who can use the unusual magic of turning iron into silver, Barca Bank holds luxurious silver and monetizes it.

This means that Barca Bank's best job is to act like a central bank.

Other than that, however, they usually lend or have a deposit system in place.

Barca Bank is issuing Barca bank vouchers that have the meaning of Treasury bonds to borrow money, or they are lending it to some nobleman, knight, or church, etc., or even depositing money from ordinary people.

The task, however, was rather limited.

Because the fact that the currency in circulation as money was a coin was a necklace.

Money, of course, made of silver, gold, or other metals, is heavy.

It's hard to carry heavy goods of value, and I can't say that they can't possibly be taken away while on the move.

For this reason, Barca Bank only had branches in the city of Fontana, in addition to the big city on Barca territory.

Essentially, a safe with as much security features as possible will be kept in the bank's branches on the land, where the gold will be stored and managed.

Depositing gold in a deposit account at Barca Bank was, in principle, the only way to withdraw it was at a branch of that city.

If the money were to be dropped off at a branch on another land, it would have taken a long time to confirm the deposit balance by contacting them in advance.

Well, still, quite a few people used it, saying it was far better than dealing with people like higher-interest lending so far.

But that, too, would dramatically change how it works if I had eyes.

Because if you have an eye, you can collectively identify individuals and manage deposit balances, loan amounts, and the associated interest.

In other words, the first thing I thought about when I saw Eye was getting out of this old-fashioned, exclusive local lender to a bank that had a modern network system in place.

If you can place an eye in each branch and have that eye verify your identity and manage your gold, you will be able to exchange gold concisely without going through a heavy coin.

Right, should I even issue a card with some sort of fingerprint or something like that on it?

If I could verify my card and identity, I would wish I could have a system where, when and how much money I could give or deposit.

If that were possible, banking could be considerably simpler than it is now.

And maybe we can increase the number of branches than we do now if we can do that.

This is how I taught Eye a lot to be a bank receptionist.
