VoucherPort
Design Korea–Japan digital-voucher ordering, issuance and encrypted ledgers to fail closed.
VoucherPort models a Korean customer's Japanese digital-voucher order as separate payment intent, provider adapter, fulfilment and encrypted-ledger concerns. Code, tests and builds exist, while live payment, production database, provider contract, PIN purchase, public deployment and support operations are unverified. Current screens and sample orders are local R&D explaining the product architecture.

Intended outcome
Separate payment and issuance failures and securely deliver sensitive PIN or receipt results bound to order and user
PRODUCT FLOW
Four steps users can understand
01 · Select product
A country, currency and product are selected from a fixed provider catalog.
02 · Order intent
Integer amount, user and product are bound to an idempotency key.
03 · Issuance adapter
Only an approved adapter is called with bounded timeout and correlation ID.
04 · Encrypted delivery
PIN and receipt results are encrypted with order-, user- and product-bound AAD.

CAPABILITIES
Designed capabilities
Multi-market catalog model
Country, currency, SKU and provider product remain explicit.
Idempotent orders
Retries of the same command are designed not to duplicate issuance.
Provider adapter
External-contract differences are isolated behind a narrow adapter and explicit error taxonomy.
Sensitive-result encryption
Immediate PIN or receipt data is protected with transaction- and user-bound AAD.
State and audit ledger
Order, provider attempt, fulfilment and failure states are recorded separately.
INTEGRATION SEQUENCE
Implementation sequence
- Catalog synchronizationApproved provider products map to internal SKUs and effective dates.
- Payment approvalOnly sample orders are allowed before a live-payment adapter exists.
- Provider issuanceThe server verifies ownership authorization and idempotency before requesting issuance.
- Encrypt resultSensitive results are protected before storage with a reviewed envelope such as AES-256-GCM.
- User delivery and auditOnly the authenticated user can reveal the result; audit retains minimal metadata.
SERVER-SIDE PSEUDOCODE · NO CREDENTIALS
Server integration sketch
Secrets never enter the browser. Every external response is verified by the server before product state advances.
const intent = await server.orders.create({ idempotencyKey });
const decision = await server.policy.evaluate(intent);
const providerEvent = await server.provider.executeSandbox(decision);
await server.ledger.appendVerified(providerEvent);SECURITY
Security and responsibility
No real PIN in samples
Marketing UI and test fixtures contain no redeemable voucher or credential.
Ownership authorization
Caller middleware must first verify transaction and user ownership.
Bounded provider calls
HTTPS, timeout, response size, correlation and idempotency are bounded.
No plaintext result at rest
Real sensitive results must not enter logs or plaintext database columns.
READINESS
Current limitations
Local R&D
There is no public deployment or production operator.
No live provider
No live voucher catalog, credential or fulfilment call is verified.
Live payment unverified
There is no payment provider, webhook, refund or chargeback operation.
Production database unverified
Managed DB, KMS, backup/PITR and data-retention policy remain required.
