You can have up to $2,000 worth of SMC Points in your account, on any given day.  This means that the value that remains in and has been redeemed from your account at the end of one day, combined, may not exceed $2,000.  Therefore, for example, if there are 1,500 SMC Points in your account and you have redeemed 500 SMC Points that day, you cannot receive more than 500 SMC Points into your account that day.
