We've just uploaded an app update for review with a new Training Wallet feature. This feature will enable club members to add money to a virtual wallet to pay for training sessions.
Rather than needing to enter credit card details for each and every paid training session club members will be able to add money to their virtual wallet. When they want to participate in a paid training session the cost will be deducted from their virtual wallet.
With members only needing to add funds if they want to or when the funds in their wallet are low this will save the club money as transaction fees are only deducted when the wallet is topped up and not each and every time a session is paid for.
