What Is a Closed-Loop Stored-Value Card?
A closed-loop stored-value card is a logic-encryption contact IC card that carries a small prepaid balance for spending inside one system — a canteen, catering chain, parking lot or staff site. Built on the Infineon SLE4442 and China-made FM4442 chip, it adds a password and error counter on top of EEPROM, so the balance is protected against casual tampering.
Because it is closed-loop — money is spent only within your own network, not on banking rails — no EMVCo or UnionPay certification is required. SLE4442 and FM4442 are pin- and command-compatible, working in existing readers. For the full international ↔ China chip mapping, see the chip selection & cross-reference table below.
Where Stored-Value Cards Fit Best
- Canteen and cafeteria payment in companies, schools and hospitals
- Catering and small-shop micro-payment within a closed network
- Parking deduction and site access combined on one card
- Small-amount prepaid spending where no banking certification is wanted
- High-volume issuance for staff, students and members

Frequently Asked Questions
Which chip is used in your stored-value cards?
They are built on the Infineon SLE4442 and the pin-compatible China-made FM4442. Both provide 256 bytes of EEPROM, a 3-byte programmable password and an error counter, accessed over the ISO/IEC 7816 contact interface.
What does "closed-loop" mean for a stored-value card?
Closed-loop means the balance can only be spent within your own system — a canteen, catering chain or parking network — and never on outside banking rails. This keeps the card simple and removes the need for payment-scheme certification.
Do closed-loop stored-value cards need EMVCo or UnionPay certification?
No. Because spending stays inside your own closed network and does not touch banking systems, no EMVCo or UnionPay certification is required. For open banking payment, a CPU card is the right choice.
Are these cards compatible with existing SLE4442 readers?
Yes. SLE4442 and FM4442 are pin- and command-compatible, so the cards work as drop-in replacements in existing POS and reader systems without hardware changes.
