Bangladesh Bank Had to Force a Shared Card Network Back Online

Card, ATM and point-of-sale payments at roughly 30 Bangladeshi banks stopped on the evening of Sunday, 4 October, after the software licences behind the Q-Cash network were switched off. Q-Cash is the shared card switch run by IT Consultants PLC, usually shortened to ITC. It sits between member banks and the National Payment Switch Bangladesh, so a fault there does not stay inside one lender. Customers found they could not withdraw cash, pay at a terminal, move money by card, or complete some QR and mobile-wallet cash-in and cash-out transactions.

The trigger was a contract fight, not a routine weekend patch. UK vendor Compass Plus, which had supplied the processing software for about two decades, revoked ITC's licences that Sunday evening. Correspondence reported by local outlets says the vendor had warned ITC in July, sent a termination notice on 2 October, and heard nothing back it considered a settlement. Compass Plus has put the unpaid bill at more than $500,000. It has not published a line-by-line account of that figure. ITC, meanwhile, was already preparing to leave the Compass Plus platform for Way4, a switch from Belgium-based OpenWay, with a migration that regulators had expected closer to 28 October.

That gap in the story matters. Bangladesh Bank summoned ITC's management and was told the outage was an accident: a server fault had forced the move to start at once, instead of at the end of the month. A notice on the operator's side described a maintenance window from 9 pm on 4 October to noon on 10 October. The vendor's account is blunter. Licences were withdrawn because the contract was over. Both can be partly true — a rushed migration and a cut-off licence — but they are not the same explanation, and customers were given neither in advance.

The central bank's payment officials treated the sudden shutdown as a breach of the rules for critical payment infrastructure. Arief Hossain Khan, an executive director and spokesperson for Bangladesh Bank, said cardholders were facing real hardship and that the regulator would issue show-cause notices to affected member banks. By Tuesday night, 7 October, digital services at 31 banks were reported back. Some lenders posted notices on Facebook, by text and on their websites. The advertised maintenance window still ran toward 10 October, so "restored" did not mean every terminal and every app was clean on the first morning.

Industry estimates have put ITC's share of the country's banking-card transactions near 70 percent. If that figure is even roughly right, the outage was a concentration problem as much as a software problem. One vendor, one operator, and about 30 banks shared a single point of failure. A shopper in Dhaka and an account holder outside the capital had the same useless card.

For customers, the practical residue is smaller than the headline. Anyone who was charged without receiving goods, or who saw a reversal that never landed, still needs the bank's complaint channel, not a social-media post. For the system, the open questions are who pays the vendor, whether the Way4 move is actually finished, and why a network this central could go dark on a Sunday night with no public warning.
