Which of the following is NOT a customization option for guest vouchers?

The correct answer is the option regarding Account Lifetime, as this is not typically a customization feature for guest vouchers. Guest vouchers are primarily designed to provide temporary access to a network while allowing organizations to maintain branding and communication flexibility. Customization options usually focus on how the guest experience is presented—this includes elements such as Business Name, which allows for the personalization of branding; Contact Information, which can be included on the voucher for customer support or engagement; and Custom Logo, allowing businesses to incorporate their branding directly on the voucher.

On the other hand, Account Lifetime generally refers to the duration of access that a voucher provides, which is typically set at a default level and not customized for individual vouchers. Instead, the focus is on the other aspects that enhance user engagement and brand representation rather than altering the timeframe of access. Thus, while it is important for network management, it does not align with the customization options available for guest vouchers themselves.
