The Plain White PVC SLE 4428 Chip Cards are blank CR80-size smart cards built around the SLE4428 chip — a contact IC with 1 Kbyte EEPROM storage and a Programmable Security Code (PSC) verification logic that prevents unauthorised data writes. That write-protect function matters if you're issuing cards into an environment where data integrity is non-negotiable.

At standard credit card dimensions (86mm x 54mm), these cards work with the card printers and encoding equipment already on your desk. They arrive blank and ready for printing, encoding, or both — the kind of flexible stock that suits access control deployments, staff ID programmes, transport passes, and photo ID schemes alike.

Sold in packs of 100, they're a practical choice for organisations that need reliable smart card stock without overcomplicating the procurement process.
