Born in the Islands

In the remote municipality of President Carlos P. Garcia, Bohol — a scattered island town with over 23,000 residents — limited digital infrastructure has long hindered access to public services. One of the biggest challenges faced by students was the absence of valid school IDs. Even when IDs were issued, many were questioned by transportation providers and businesses, leading to denial of essential benefits such as student fare discounts.

Aid distribution on the island was another major pain point. Large-scale relief efforts were often chaotic, crowded, and inefficient, lacking any centralized, fraud-proof verification system. The result was long lines, duplicate claims, and confusion — especially in emergencies when timely and orderly support mattered most.

SecureLink™ QR was designed in direct response to these issues. By embedding cryptographically signed QR codes on waterproof PVC cards and a piece of paper, the system enabled tamper-proof, one-time verifiable IDs and vouchers. These were not just QR codes — they were keys to legitimacy, restoring public trust and personal dignity.

With the generous support of V Cutamora Construction Inc. and the Ang Probinsyano Partylist, the initiative began by distributing free digital voucher cards and school IDs. What started as a small-scale tech deployment became a model of decentralized, secure identity and aid management.
