# 5.1 The Access Card

The Access Card is the flagship consumer product. It is a physical and digital debit instrument that interfaces directly with the Accessth Fog.

Traditional crypto cards are custodial. You must top them up (sell crypto for fiat) before spending. The Access Card is authorization-based.

Mechanism of Action:

1. The user swipes the card at a coffee shop (Fiat Point of Sale).
2. The card sends a request to the Accessth Node Network.
3. The Node verifies the user's ZK-Proof of Rights.
4. The Protocol instantly liquidates the exact amount of ETH required from the Fog Pool into Fiat and settles with the merchant.
5. The user's Permission Set is decremented.

There is no "Top Up." There is no "Selling in advance." The asset remains ETH until the exact second of purchase. This maximizes the user's exposure to the asset's upside and removes the friction of currency conversion.
