Membership Card

While present in GG's, your identification (and access to the rest of the club) is tied to your membership card.
Membership cards can be loaded with credit at the currency exchange counter. Balances can be checked manually by applying pressure to a discreet button on the card itself, at which point the numerical total will appear on the card, fading when pressure is removed.
The button on membership cards is equipped with soul-recognition; the imprint of a person's personal signature on a most essential level. This allows the card to only be used and accessed by the person to whom the card belongs.
Membership Cards come in four varieties: Pink, Red, Purple, and Black. A fifth blue card marks an employee, functioning essentially the same as standard member cards (though with some employee-specific accesses and features.)

Pink Membership

Considered a "temporary" membership, these cards are most often used as gifts from members to non-members, or used as promotion to acquire new memberships. This card only allows [elevator] access for pre-chosen locations; whatever is being offered to (or has been purchased for) the cardholder.
This card contains a pre-loaded balance that cannot be re-loaded; patrons looking to become members of the club must thereafter apply for a standard membership.

Red Membership

Red cards are the standard memberships of GG's. This card holds the identification of the individual and allows for access to the rest of the club.
[Floor access] includes free access to floors one and two, as well as access to [Recreation]. If paid for, red cardholders may also enjoy the benefits of a [private room] and access to [B1].

Purple Membership

Purple cards are considered VIP memberships, and can only be acquired after several very expensive visits. This card color is also a signal that the cardholder is a "high roller," and so staff will generally show favoritism towards these clients.
Floor access includes free access to floors one, two, and [Recreation]. Purple cardholders will also enjoy the benefit of a [private room] made available at all times during the member's stay, provided that 48 hours notice are given for preparations to be made. In addition to these perks, purple membership clientele are also offered the benefits of access to floors [B1] and [B2].

Black Membership

Black cards are nearly unseen in GG's, though they're the highest level of status that a patron can hold. These cards grant access to nearly all levels of GG's, and come with a priority status that all staff will adhere to strictly. Though rarely seen, all staff are informed of their existence and are expected to know the appropriate protocol when encountering one.
Floor access includes all floors, and comes with a permanent and personalized [private room], allowing for a black card member to have their own home away from home.
Currently, there are only 5 black card holders.

Blue Employee Cards

While not technically a membership card, employees are all administered a blue employee card to allow them to navigate the club. Things like credit totals, clocking in and out of work, and the employee's next shift can be quick-accessed via the button on the back.
This card offers access to dorm floors (and the employee's specific dorm room), any and all assigned work floors, and will keep track of this data through the [database].
