US retailer-backed Merchant Customer Exchange (MCX) is winding up a beta test of its CurrentC payment service on 28 June, with no indication of future plans.

“We have not yet determined the future timing of CurrentC but we will keep you posted,” said the firm in a message on its website, addressed to participants in the Columbus, Ohio, test.

After the end-June date, users will no longer be able to make payments in participating stores using the CurrentC app on their phones.

Users can close their account before 28 June by calling customer care and, after that date, all active accounts will be automatically disabled and users will not be able to access their account from the CurrentC app.

While not a formal closure of MCX, it’s clear the payment service is now winding down over the next three weeks. The writing has been on the wall since last month when the firm postponed plans for a nationwide launch, or even earlier when it suffered other mishaps.
