No account needed

One instruction you can give six ways. Drag the amount and watch the SMS counter move, because that limit is real.

What you point it at

Photograph it. That is the whole step.

A fees slip, an ajo card, a meter number, an account scribbled on the back of something. KoreX reads the paper you did not choose, and takes over the tedious half.

ReadingRead

It reads the reference, not just the account.

Anyone can copy the account number off a fees slip. The reference is the part that tells the bursar whose child paid, and it is the part everybody mistypes — then spends a week proving it on WhatsApp.

Pay fees with your PIN

The school reconciles it themselves. You send nothing to anybody afterwards.

The everyday things

All of this works with your data off.

Ten things you do most weeks, and the small thing KoreX adds to each one. Every row runs in a chat, in a text, or in a USSD menu.

Send to any bank account

The same instruction works over SMS and USSD with no data

Send by phone number

Your recipient needs no KoreX account, the money lands in their bank

Pay bills

Reminders escalate across channels before the disconnection date

Airtime and data

Buy for someone else by sending a request they approve

Voice note instructions

Igbo as a fifth language, alongside English, Pidgin, Yoruba and Hausa

Photo of an account number

Also reads a handwritten list, a POS slip and a printed invoice

Scheduled payments

Reminders reach the payer, not only your own phone

Spending analysis

Reads your linked bank accounts, so it sees spending KoreX did not process

Bulk transfers

From a voice note, a spreadsheet, or a roll call in a group chat

Freeze from any device

Freeze by USSD too, which still works when the phone is gone

One instruction, many ways in

Use whichever one your phone can manage today.

Data finished, so you dial. On a bus, so you talk instead of typing. Borrowing somebody’s handset, so you use the USSD code and leave nothing behind on it. The instruction is the same one every time.

Nothing is a lesser version. The USSD menu can do what the chat can do, because they are the same request underneath.

When conditions are bad

It works with whatever you have left.

Every other money app assumes a charged phone, a live bundle and a decent signal. Set yours to how it actually is and watch what survives.

ways in still open to you

Your bundle finished. Nothing else did.

The channels still standing are the ones that never needed data in the first place. Sending money is the same three steps it was this morning.

  • WhatsApp

    Needs a data bundle.

  • SMS

    No data needed. As fast on 2G as on 4G.

  • USSD

    No data, no airtime, no app. 2G is all it ever needed.

  • Voice call

    Speak it. Five languages, 2G is enough.

  • Email

    Needs a data bundle.

  • Pay link

    Needs a data bundle.

Ajo and esusu

The collector stops being a person with a notebook.

KoreX tracks who has contributed for the cycle and asks the ones who have not on whichever channel they answer.

Every member sees the same ledger and the same rotation, which removes the argument that ends most groups.

Money coming to you

You never have to ask who sent it.

Ask someone for money and KoreX gives that one request its own account number. They pay it from whatever bank app they already have, and it arrives labelled with what it was for — no “I’ve sent it” followed by a blurry screenshot and a guess.

The number expires with the request, so you can send it to someone you barely know without handing over an account number that follows you around forever.

The awkward part

What you do when it goes wrong.

Every one of these is a normal Saturday rather than an edge case. None of them needs the app, a browser, or us to be having a good day.

If it goes wrong

Works from any handset

  • 01Your phone is gone

    Text FREEZE from any phone

    Every payment stops, on every channel. No app, no login, no waiting for us to open.

  • 02You sent it to the wrong person

    Reply WRONG in the thread

    A recall opens with their bank at once. Most never get this far: KoreX shows you the account name before you confirm.

  • 03Your data finished halfway through

    Dial USSD string

    Carry on where you stopped. Same request, on a channel that never needed a bundle.

  • 04Somebody will not stop asking you for money

    Reply STOP, once

    They lose every channel, not just the one you replied on. No second attempt from another number.

  • 05You have forgotten your PIN

    Text PIN

    The same identity check as day one. Nothing moves until it is done, for you or anyone else.

  • 06You think someone has been in your account

    Text FREEZE, then PIN

    Every open session ends and a new PIN is set before a naira can move.

Nothing here is behind a tap, because on the day you need it you should not have to go looking. Screenshot it — every line works from a borrowed phone with no data on it.

Who uses it

Built for the phone in the other person’s hand.

The student

Sends money at the end of the month when the data bundle is long finished.

The trader

Photographs the account number a customer wrote down and pays it without typing a digit.

The ajo collector

Stops carrying a notebook and stops chasing six people by hand.

The person abroad

Sends home to a parent who answers a phone call and never a chat app.

Getting started

Four steps, and none of them are a download.

01

Say hello

Message KoreX on WhatsApp number or dial USSD string. Both open the same account.

02

Prove who you are

Your BVN and a photo of your ID. It takes one pass, not three.

03

Set your PIN

Four digits. Nothing leaves your account without it, on any channel.

04

Your number appears

An account number lands in the chat. Money can arrive immediately.

Security

Money you can stop with one message.

Licence, regulator and certification text

A PIN on every payment

Four digits, required on every channel, including a USSD session and a voice call.

Freeze from any phone

Lose the handset and you can freeze the account from any other phone, by message or by USSD.

Your money is in your bank

KoreX settles into the account you already own. There is no KoreX balance to be frozen and nothing to withdraw.

Nobody holds your account number

Each request carries its own number, which is retired afterwards, so a permanent number never circulates.

Encrypted, in transit and at rest

Including the images you send it and the transcripts of what you say to it.

Pricing

Free, and not the kind that expires.

Personal KoreX has no monthly fee, no per-transfer fee and no tier above it to be upsold into. It is free because the business side pays for it, which is a better arrangement than the usual one where free means your spending is the product.

Costs you nothing

  • Transfers to any Nigerian bank
  • Airtime, data and bill payments
  • Every channel, including voice and USSD
  • Ajo and esusu, however many people
  • Spending summaries and receipts
  • All five languages

What you do pay

Your network charges for the USSD session and your bank may charge its own transfer fee. Both go to them, not to us, and KoreX shows you the cheaper channel before it sends.

USSD session cost

Open an account

Selling something? The business side is where the pricing is.

KoreX and Kampe

One knows what you have. The other knows what is already spoken for.

Kampe aggregates every account you hold and never moves a naira. KoreX moves money, so the two are separate products joined by one consented feed running in a single direction. KoreX publishes what you have committed to — the ajo hand due on Friday, the rent standing order, the school fees — and Kampe subtracts it before telling you what you can spend.

KoreX never reads Kampe. Switching the connection off deletes what was shared rather than hiding it, so Kampe stays literally read only.

Without the feed

A balance that says ₦180,000 and says nothing about the ajo hand you owe on Friday.

With it

₦180,000, of which ₦96,000 is already promised this month. ₦84,000 is the number that is actually yours.

Reach a person

Type your problem into the same chat you pay from. If KoreX cannot settle it, a human picks it up in that thread.

Support hours

Where it works

Every Nigerian bank KoreX’s partner reaches, plus transfers across supported African countries.

Partner banks and rails

Languages

English, Nigerian Pidgin, Yoruba, Hausa and Igbo. Typed or spoken, on every channel that carries voice.

Questions

The things people actually ask.

If something here is missing, it is probably because the honest answer is that we have not built it yet.

Ask me something. Pick one below.
