Currently it is $10,000 for Consumer BIN cards, and $200,000 for Business BIN cards.
Consumers can't create multiple cards to increase the limit, but in most cases, businesses may create multiple cards with $200k each. For example, if there is $1 Mil needed for a marketing campaign, you can put $200k on five different cards per month, each attached to the same business or campaign.
