This is the chip used in transit, banking and government ID programmes.
Key Features
- AES-128 (and 3DES) hardware encryption with mutual, session-key authentication.
- Genuine file system: applications, files and access keys managed independently.
- 500,000 write cycles and 10-year retention for long-life credentials.
Typical Applications
- Public transport fare collection
- Banking and payment cards
- Government and national ID
- High-security campus and campus access
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.
