The SLE5542 is a contact chip card: it has no antenna and is read by inserting it into a slot reader. Its 256-byte EEPROM with a programmable security code is the classic design for stored-value schemes — laundry cards, canteen cards, prepaid utility meters — where the value lives on the card rather than in a database.
Key Features
- 256-byte EEPROM with byte-wise write protection and a programmable security code (PSC).
- No battery and no antenna — the card is powered by the reader contacts.
- Fudan FM4442 equivalent available at a lower cost; same instruction set.
Typical Applications
- Laundry and vending stored-value cards
- Prepaid electricity and water meters
- Canteen and copy-room cards
- Membership and loyalty with on-card balance
Customisation Options
Every card is produced in our own factory, so the card body and the artwork are handled under one roof. Choose offset or digital printing for full-colour artwork, add a magnetic stripe (LoCo / HiCo), a signature panel, embossed numbering, a scratch-off panel or a punched slot. We can also pre-write your UID, NDEF record or sector keys so the cards go straight into your system on arrival. Artwork is checked by our engineers before plating, and we send a digital proof for approval.
Samples, MOQ & Lead Time
MOQ is 100 pcs per chip specification. Stock samples are free of charge and you only cover the shipping — they ship within 1–2 business days by DHL or FedEx. Custom sampling takes 3–5 days and carries a sample fee, which is credited back in full once the related bulk order reaches USD 10,000 or more. Standard lead time for 10,000 cards is about 12–15 days after artwork approval. Every card is 100% RF tested before packing, and we ship worldwide on EXW, FOB, CIF or DDP terms.
