No ID, No Aid

Cash-based assistance is now the preferred humanitarian aid modality, with UNHCR, WFP, and UNICEF collectively delivering billions in cash transfers annually. But digital payment systems require identity verification that 20–30% of displaced populations cannot satisfy. Refugees often lack government-issued ID, SIM card registration requires ID in most countries, and KYC (Know Your Customer) regulations from financial service providers systematically exclude the most vulnerable. The result is a paradox: digital cash is more efficient and dignified than in-kind aid, but digitization itself creates a new exclusion barrier.

Digital exclusion from cash assistance forces the most vulnerable people back to in-kind aid distribution — less dignified, less flexible, and more expensive to deliver. In Jordan's Azraq and Zaatari camps, biometric-linked cash systems serve ~100,000 refugees effectively, but populations outside formal camps and those who avoid registration remain invisible. The ICRC warns that centralized biometric databases in humanitarian contexts create surveillance and persecution risks if compromised.

Biometric systems (IrisGuard iris scanning in Jordan) enable identity verification without documents but require expensive enrollment infrastructure and create data protection risks. UNHCR's blockchain pilot (Stellar/USDC) delivers funds to mobile wallets but still requires initial identity enrollment. Prepaid cards and vouchers bypass KYC but lack the flexibility and dignity of cash. The ICRC's Humanitarian Token Solution uses privacy-preserving QR codes that eliminate personal data sharing, but is in early pilot. Mobile money (used in Somalia) works where telecom infrastructure exists but excludes areas without coverage. No system simultaneously prevents duplication fraud, works offline, protects against database compromise, and is usable by people with no digital literacy.

Privacy-preserving digital identity systems using zero-knowledge proofs or similar cryptography — verifying "this person is a registered beneficiary" without revealing identity. Offline-capable digital payment systems for settings without connectivity. Regulatory frameworks creating humanitarian exceptions to standard KYC for small-value transfers. UX design for digital illiterate users that maintains security without requiring literacy or smartphone proficiency.

A team could prototype a zero-knowledge proof system for humanitarian aid eligibility verification, demonstrating how beneficiary status can be confirmed without transmitting personal data. Alternatively, a team could design and test an offline-capable payment token system usable by people with no prior digital experience. Cryptography, UX design, and humanitarian technology skills apply.
