* Santander Brasil, Bradesco among potential buyers -Valor
* Transaction could be valued up to $761 million
SAO PAULO, March 7 (Reuters) - Citigroup Inc plans to finalize the sale of its consumer financial units in Brazil by the end of the month in a deal worth as much as 1.5 billion reais ($761 million), newspaper Valor Economico said in a report on Thursday.
About three banks, including Banco Santander Brasil SA and Banco Bradesco SA, may consider bidding for Citi's Credicard and Credicard Financiamentos and were allowed to access a data room, Valor said, citing unnamed sources.
With the sale, Citigroup could be making progress in a longstanding plan to exit noncore business areas in key markets.
On the other hand, a purchase of Credicard could help bulk up the merchant acquiring business of any of Brazil's top three private-sector banks, which currently with their units dominate more than 90 percent of the card-payment processing market.
The sale could be concluded by the end of this month, in time to have a positive impact on Citi's first-quarter results.
Bradesco and Santander declined to comment on the report, and Citigroup were not immediately available for comment.
