foopgp does not sell its physical security keys: it provides them to its members as soon as their cumulative subscriptions have generated 6.42 Ɉ (≈ €146 in May 2026).

Available models, at the member’s choice and according to stock:

• YubiKey 5 NFC
• Nitrokey 3A NFC
• Soon: YubiKey 5C NFC

All at the same threshold — the association absorbs the margin differences.

Why a djis threshold, not a price in euros?

Because the threshold expressed in euros evolves automatically with the stingynalty — a factor largely offsetting inflation in euros, rising by 5 per mil each month (current parameter ). The threshold is never fixed: it climbs mechanically, month after month, rewarding the pioneers.

On the curve above, every passing month makes the same amount of djis more expensive in euros:

• In July 2025 (AGE of Pelleautier, introduction of the parameter): ≈ €114 for 6.42 Ɉ.
• In June 2026: = €149.79.
• In May 2027: = €199.09.
• In April 2028: = €268.77.
