Beem It, the mobile instant payments service owned by three of the country's largest banks, is preparing to broaden its business activities as fresh data reveals booming growth at its main rival, Osko. The Beem It business, which last month lost its inaugural CEO Mark Woods after only five months in the role, is struggling to match the rapid growth of the BPAY-owned Osko service .BPAY revealed yesterday that Osko processed A$12.5 billion worth of payments in the three months to the end of August, up from $6.5 billion in the three months ending in May.Osko also grew the number of transactions processed through its platform from 10 million to 15 million in the same three-month period.While Beem It has not published any volume data since it launched in May, the business has suffered a string of operational headaches, including an outage in June that delayed customer transactions for several days.Beem It is now preparing to roll out new payments capabilities to regain strategic momentum.According to disclosures on Commonwealth Bank's website, Beem It has begun working on a project to upgrade its platform to handle payments beyond only cash transfers for Visa and Mastercard debit card holders.CBA has told customers that credit card transactions will be added to the service: "At this stage, customers can only upload an Australian Visa or Mastercard debit  card to the app," the bank said."Beem It are currently developing the functionality to use a credit card."A Beem It spokesperson could not say when credit card users would be given access to the instant payments service, but confirmed the company was looking at ways to expand the platform."Beem It continues to evaluate a host of payment options for the platform, for a variety of use cases," the spokesperson said.There is also speculation in the payments industry that Beem It is developing a payments service for merchants that would allow debit cardholders to make instant payments for point of sale purchases.Those suggestions are gaining currency following the secondment of Angela Clark - CBA's former head of small business banking - to take over as acting CEO of the nascent company.Clark has inherited a swathe of strategic problems, including unresolved matters relating to the company's branding.The "Beem It" brand has created confusion among customers because another company that trades as "Beam Wallet" is also trying to establish a foothold in the Australian payments market.The managing director of Beam Wallet Serdar Nurmammedov told Banking Day that a dispute between his company and the bank-owned Beem It business had not been resolved."They have withdrawn their trademark application for the right to use our company name 'Beam Wallet'," Nurmammedov said."But we have received advice that we should also challenge the use of 'Beem It'."
