Union Smart manufactures financial-grade and government-certified Infineon SLE77CLFX2400PM High-Security Smart Cards for banking institutions, national identity projects, defense contractors, and enterprise security providers worldwide. Built on Infineon's 16-bit security controller architecture with SOLID FLASH technology, the SLE77CLFX2400PM is certified to Common Criteria EAL5+ (High) and EMVCo standards. Featuring powerful hardware cryptographic coprocessors (supporting RSA up to 4096-bit, ECC up to 521-bit, AES-128/192/256, and Triple-DES) and true dual-interface communication (contact ISO/IEC 7816 and contactless ISO/IEC 14443 Type A/B), this card provides non-negotiable protection against physical tampering, side-channel attacks, and data interception.
Our engineering team delivers standard CR80 cards, dual-interface inlays, and customized credentials meeting international banking and civil registration benchmarks:

As a specialized smart card factory, Union Smart controls every phase of production in dust-free cleanroom environments:



EAL5+ (Evaluation Assurance Level 5 Augmented) confirms that the Infineon security microcontroller has been subjected to rigorous vulnerability assessments by independent testing laboratories. The chip includes active internal shielding layers, dynamic sensors against physical decapping, and algorithmic countermeasures against Differential Power Analysis (DPA), Simple Power Analysis (SPA), and electromagnetic fault injection attacks.
Yes. Depending on your system infrastructure, we can deliver blank initialized silicon for client-side OS issuance, or provide cards pre-loaded with Java Card OS (with GlobalPlatform compliance) ready for immediate applet loading (EMV payment applets, PKI credentials, or e-Passports).
Yes. The SLE77 architecture supports both contact (ISO/IEC 7816) and contactless (ISO/IEC 14443 Type A & B) interfaces using a single silicon controller. Users can insert the card into traditional contact ATM/POS terminals or tap the card against contactless readers without requiring dual chips.
For national ID and civil identity documents requiring a 10-year operating lifespan, we recommend 100% Polycarbonate (PC) construction. Polycarbonate layers are fused using high-pressure thermal lamination into a solid monolithic card body that cannot be delaminated. It supports internal laser engraving of citizen photos and variable alphanumeric data that cannot be altered or scraped off.
