Customer requires an 8GB Micro SD card with hardware encryption for secure offline data delivery. Traditional approaches rely on either encrypted SD cards with built-in crypto chips or external encrypted card readers—both introduce extra hardware cost, limited compatibility, and complexity in deployment.
Replace the encrypted Micro SD workflow with CARDSOON Data Card + TH80 distribution terminal + CryptoKey™ encryption + professional card reader. This combination delivers equivalent or stronger hardware-level security, while reducing total cost, improving compatibility, and adding value through physical media branding and lifecycle management.
No need for proprietary encrypted SD cards or dedicated card readers. Standard USB card reader works on any PC/Mac/Linux.
CryptoKey™ hidden partition + AES-256/RSA-2048 + offline physical delivery = air-gapped security against software attacks.
USB interface works on any modern OS without driver installation. Standard form factor avoids Micro SD slot dependency.
Embedded data viewer allows end users to open content directly from the card—no third-party software required.
| Requirement | Customer's Original Ask | CARDSOON Solution | Status |
|---|---|---|---|
| Storage Capacity | 8 GB Micro SD | Data Card 8 GB / 16 GB / 32 GB / customizable | ✓ Exceeds |
| Encryption Type | Hardware encryption (chip / reader) | CryptoKey™ AES-256 + RSA-2048 in hidden partition + offline delivery | ✓ Exceeds |
| Anti-tampering | Required | WORM (Write-Once-Read-Many) + hash verification + tamper-evident packaging | ✓ Exceeds |
| Physical Form | Micro SD (tiny card) | Credit-card form factor (85.6 × 53.98 mm) | ~ Different |
| Interface | SD card slot | USB 2.0/3.0 via included reader — works on any device | ✓ Better |
| Software Attack Resistance | High (hardware chip) | High (offline + AES-256 + WORM) | ✓ Equal |
| Physical Attack Resistance | Medium (SD cards easy to clone) | High (hidden partition + CryptoKey binding) | ✓ Better |
| Cost (per unit) | High (encrypted SD + reader) | Medium (data card + standard reader) | ✓ Lower |
| Scalability | Limited (per-device licensing) | Centralized via TH80 terminal — bulk burning | ✓ Better |
| Branded Cover Print | Not available | Built-in color printing on card surface | ✓ Added Value |
CARDSOON solution meets or exceeds every functional requirement of the encrypted Micro SD spec, while reducing total cost and unlocking additional value (branding, lifecycle, audit trail). The only trade-off is physical form factor: data card is larger than Micro SD, but reads via universal USB instead of requiring an SD slot.

Compact burning & printing terminal. Auto-grabs source files, applies CryptoKey encryption, burns to data card, prints branded cover.
Credit-card form factor, ISO 7810 standard. Self-developed chip 0.55 mm, full card 1 mm thickness. Hidden partition for CryptoKey.
Self-developed control chip. Recognizes CryptoKey™ hidden partition and WORM lock. EDO stable circuit for physical-level read reliability.
TH80 terminal can be deployed in two modes: Push Mode (PC → TH80 writes to card) for high-volume operations, or Pull Mode (TH80 grabs from network share) for unattended kiosks. Both modes fully support CryptoKey encryption pipeline.
CryptoKey™ is CARDSOON's proprietary encryption engine embedded in the data card's hidden partition. It creates a physical-level copyright lock that binds data to the specific card medium—making cloned or copied data unreadable.
Invisible storage area for crypto counter and key material. Standard OS cannot detect or mount it.
Normal users cannot read or modify the partition, ensuring security across the distribution chain.
Encryption keys are generated on-the-fly during the burning process—each card receives a unique key.
Cross-platform SDK lets customer's software integrate auth/installation counter controls with minimal dev effort.
API calls must pass customer's unique license key verification—software vendor retains full control.
License codes can be updated anytime—even CARDSOON cannot access them after deployment.
