I found: This term relates to the funds which are automatically reserved against a card account. When an authorisation is performed against a bank card and an authorisation code is returned, the funds are 'reserved' to prevent the card holder going over their credit limit. The reserved funds are only held for a short period of time, typically between 1 and 5 days, after which if the transaction has not been settled, the funds are returned to the cardholder account

The bank would have this liquidity during the reserve period- In a sense it is money accumulated. I think that money that is held for a period in prepaid card systems, accounts like Paypal and othersystems where you pay in and have credit to spend when you want without carrying cash or making a transfer could qualify as "remansados" as well, although that might be better described as "funds on reserve". Prepaid cards are a big window for money laundering as they are hard to trace and easy to move across borders. [PDF]
