US banks are struggling to maintain the integrity of their US-branded accounts after they were used to store credit card information belonging to customers who were unable to access their bank accounts. 

According to the Wall Street Journal, the first national bank of Hawaii is the latest bank to sign up to the Sunflower bank account, which allows US-residents to access the bank account of their friends and relatives.

Sunflower Bank, based in Waikiki, is owned by Sunflower Financial Group, a unit of American Express, and is part of a global financial technology firm, Fidor, founded by Chinese billionaire Zhang Zhongwei.

The company has not yet responded to Al Jazeera’s request for comment.

In a statement on its website, Sunflower said: Sunflowers new account is a convenient, secure and secure solution to store and manage credit card data. 

“Our aim is to provide a service that provides the convenience of being able to easily access and manage your credit card and other financial information.

Sunflowers service is free of charge, so no extra fees are required. 

The Sunflower account has been fully operational for the past six months and has processed over 3.2 million transactions, which has helped us reduce the number of transactions from US$8 million to US$2 million in less than three months.”

Sunflower Financial has been working with the US Securities and Exchange Commission (SEC) on implementing new rules that would allow US-based financial institutions to operate on a level playing field with foreign-based competitors.

According to Sunflower, Sunflower’s new bank account is the first of its kind in the US. 

SunFlowers account is unique because it does not store credit cards on its servers, but instead uses the Sunflower’s own network of servers. 

 “In a previous instance, the Sunflows account was linked to an account in a third-party payment processor that was linked in the same manner as Sunfloms account.

Sunflower has removed this duplication, but it does have a limited number of Sunflower accounts available, which are accessed on the SunFlowers platform by individuals who are not directly associated with Sunflower,” the statement said.”

As such, SunFlows account is not linked to Sunflones payment processing company and is a separate entity.”

Sunflows new bank was launched on November 15, and has already opened up to $1 million in new deposits.

The bank has already added its first customer, who is a resident of California, to its roster of customers.

Sunflights new customer is a local resident of Hawaii, who told the WSJ that she is a “major” customer of Sunflies new account. 

In addition to SunFlowing’s new account, Sunpac has also been set up as an online bank with the aim of enabling its customers to make online payments in their own name. 

With the Sunpac account, customers can send money to friends and family members, but they can also make online deposits.

Sunpac says it has about 30,000 accounts open for users in the United States, Australia and New Zealand, and that the company plans to expand its network in the coming months. 

A spokesman for Sunpac told the WSJ that Sunflaws new account has not been linked to any Sunpac transaction, and there is no link between the account and the company’s online banking services.

“Sunflaws customers can withdraw money from Sunpac without being tied to Sunpac,” Sunpac said. 

Al Jazeera has contacted Sunpac for comment and will update this story when we receive a response.
