Tiered verification

Methods and devices for evaluating risk profiles for potential participants in e-commerce transactions, such as online wager gaming, are described. Player attributes such as identity, age, location, and/or residence may be profiled using data service providers ("DSPs"). The best available DSP(s) may be selected, e.g., according to the jurisdiction. Players may be evaluated according to DSP scores and assigned to levels or "tiers" with predefined attributes, e.g., predefined transaction limits. For example, relatively lower-risk players may be assigned to tiers with relatively higher deposit and withdrawal limits, and vice versa. Efficiencies may be created by differentiating verification steps that are performed during the registration process from those that are performed when a player attempts to make a transaction.
