IMPS is designed for real-time bank transfers and is available 24 hours a day, 7 days a week, including weekends and bank holidays. This makes it useful for betting deposits where users want funds transferred without waiting for normal banking hours.
However, the speed of a sportsbook transaction can still depend on the operator. An IMPS deposit may be transferred quickly through the banking network, while the sportsbook may take additional time to confirm and credit the funds.
For withdrawals, the sportsbook must first review and approve the request before sending the money through IMPS. Therefore, IMPS itself can be fast, but the complete withdrawal time depends on the operator's processing procedure.
