Before BiMPay There Was CarIFS: The Rail We Gave Up

When BiMPay launched in June, the Central Bank billed it as the national instant payment system, a rail the country owns. A home-grown payment rail is not new to us, though. Until 2021, the island ran its own card network. It was called CarIFS, a name that used to sit on the debit cards in our wallets. The difference is ownership: CarIFS belonged to the banks that ran it, while BiMPay is the first everyday rail the country itself owns, and the story of how we gave CarIFS up is the clearest argument going for why that matters.

I told the Pix side of this in BiMPay vs Pix, where Brazil built a public payment rail and used it to pull everyday payments back from the card networks. Barbados lived a smaller version of that story years earlier, and then went the other way.

The rail we already had

CarIFS stood for Caribbean Integrated Financial Services Inc., and it was run for the local banks by a processor called Prism. Accounts of when it started differ: the Bankers' Association dates its development to 1994, while Prism's own history places the switch's formation in 1995. Either way, it ran for more than two decades as the domestic switch that tied the banks' and credit unions' ATMs and card terminals together, so a debit card issued by one institution worked at a machine belonging to another. In its early years it already linked more than 100 ATMs and around 3,500 card terminals across the island.

CarIFS was built and priced as local plumbing, so a card payment carried a small flat fee and an ATM withdrawal a low fixed charge. Its one weakness was the one that ended up mattering: its cards were magnetic-stripe, the kind you swipe, when the rest of the world had moved to chip-and-PIN.

Why the banks walked away

Barbados Today reported in September 2020 that the island's financial institutions were moving to Visa and Mastercard debit as CarIFS wound down. The reason the banks gave was security. A magnetic stripe is easy to clone, a chip much harder, and chip-and-PIN had become the standard everywhere else. The new cards also did things CarIFS never could: contactless taps, online purchases, and payments overseas. Bringing CarIFS up to chip on its own would have cost millions, the Bankers' Association said, and the banks judged that money better spent joining the global networks as issuers.

The switch did not happen all at once. CIBC Caribbean moved first, in November 2020. The City of Bridgetown Co-operative and the credit-union league followed about a year later, in November 2021. For a stretch in between, the island was running on two different card worlds at the same time.

What it cost at the till and the ATM

Card payments got more expensive after the change. The ATM and the shop counter are worth taking one at a time, though, because they did not move the same way.

There is really only one public source for the actual numbers, and it is not an official one. In a 2022 Nation News "Tech Talk" column, Terry Jones put point-of-sale fees at 25 cents a transaction under CarIFS against 2 per cent and up afterwards, and ATM withdrawals at around BBD $1 before against BBD $4 and up after. That is one columnist's account rather than anything official, so I read the figures as his own. He also called shutting CarIFS "a huge error." Merchant reluctance on small sales predates all of this, for what it is worth: back in 2017, under CarIFS, a public notice had to remind merchants that a minimum spend was against the rules.

The fee question had been left with the banks from the start. When CarIFS published its own transition FAQ in January 2021, its answer on whether ATM and point-of-sale fees would change was only that "your financial institution will advise you of any change in fees related to your new card."

Ten months later, what is not in dispute is that the fees climbed high enough for the Central Bank of Barbados to step in. Effective 1 November 2021 it capped cross-bank ATM withdrawals at BBD $3, after the Governor said some had reached as high as BBD $6.50, and it made debit payments at the till free for cardholders. You do not cap a fee that nobody is complaining about. Whatever the exact figures were, the Central Bank stepping in tells you plainly enough that moving to Visa and Mastercard made everyday card use more expensive.

Even after CarIFS, the plumbing was rented

When CarIFS closed, the rails that carried on underneath our banking were not really ours either. The Automated Clearing House that settled interbank payments was run by a separate company, the Barbados Automated Clearing House Services Inc., rather than by the Central Bank. Its real-time payments layer was built by an American vendor, PaySett Corporation out of Atlanta, on that firm's platform. The Central Bank ran its own high-value settlement system, but the retail payment plumbing sat with private and foreign-supplied providers.

That is where BiMPay finally breaks the pattern. It was built for the Central Bank by the technology firm Montran, and it is the first time the Bank fully owns the rail that ordinary payments run on. Ownership has a money side too. Card-network payments send a share of every transaction to the foreign schemes that run them, the kind of leakage Pix made famous in Brazil, and Barbados has been quietly paying a version of it ever since CarIFS went away.

There is a deeper reason this fell to the Central Bank, and the Governor has made the case himself. In a July 2026 article, Kevin Greenidge argued that a payment rail is a network, worth almost nothing unless everyone is on it, so no single bank will build one that mainly helps its own customers move to a rival, and every bank has a reason to wait for someone else to go first. On an island of fewer than 300,000 people, with several of the largest banks answering to parent companies focused on other markets, that wait does not end on its own. And only a central bank can offer final settlement in central bank money, funds on the Central Bank's own books, which is what makes a transfer irrevocable rather than a promise between two commercial parties. It is the operator arguing for its own role, but it lines up with the history on this page: left to the market, the island kept renting its plumbing.

What BiMPay actually reclaims

Against that history, what BiMPay does is easy to see. Person-to-person payments are free for individual users, and the Central Bank says that is permanent. Small-business scan-to-pay is free too, for businesses under BBD $10,000 in daily revenue, and no institution may charge anyone a BiMPay fee before 15 September 2026; after that date, a business fee can only appear once its bank has filed the fee structure with the Central Bank, received written approval, and given the customer advance notice. There is no terminal to rent, no per-transaction fee eating the small sale for a business under that revenue line, and the money settles straight into the account, instantly. The small-purchase penalty that both CarIFS-era and card-era shopping carried, in different forms, simply is not there.

The way in is different, a phone and an alias instead of a plastic card and somebody's terminal, but the job underneath is the same: moving money between local institutions. That is CarIFS' old job done again, and done better, on a rail the country owns outright.

I should be straight about the limits, though. BiMPay is about six weeks old and still in its first phase, and the first month had real bumps, including government salaries that ran late over badly formatted payroll files. Even so, the Central Bank's own figures have the rail working 99.8 per cent of the time across its first 750,000 transactions, with most of the trouble traced to individual institutions rather than the switch itself. It also does not replace card-present checkout everywhere. Visitors keep arriving with Visa and Mastercard, and those cards still run the tourist economy, so the foreign networks are not going anywhere. What BiMPay reclaims is narrower: the layer CarIFS used to hold, the resident paying a resident, the customer paying the corner shop.

We had a home-grown rail once and let it go, and it cost us at the till and the ATM until the Central Bank stepped in. BiMPay is the second run at a domestic rail of our own, and the first the country actually owns. If you want the mechanics, the launch explainer walks through how it works, I wrote up its first weekend in real use, and BiMPay vs Pix sets the same argument on a national stage.
