A Health Security Organization (HSO) service method and system provides healthcare service vouchers which allow an individual or an entity to purchase and store shares which correlate to CPT (Common Procedural Terminology) codes and are exchangeable for healthcare purposes. The shares can be purchased individually or in bulk packages and are transferable through a provider or provisionary of healthcare needs including pharmaceuticals. The shares are transferable, non-expiring, and usable at any health care provider willing to exchange the shares for currency in a similar fashion to an exchange of services with an insurance or credit card holder. The share transfer provides immediate payment for services rendered. Additionally, the cards can be utilized in such a fashion that if repetitive services are needed they can be acquired in a more economical method via bulk purchasing. Share transfers are redeemed by a member and provider via internet accessible computer system.
