Inlays and tags, designed and assembled in Shenzhen.
RFID at Cardz China is a custom assembly business, not a re-seller business. Antennas are designed in-house, matched to the chip and the form factor — a 13.56 MHz wristband for a hospitality access programme has a different antenna geometry to a 13.56 MHz badge for a stadium turnstile, and a different again for a UHF inventory label.
We have shipped MIFARE DESFire across transport and government rollouts since 2009, EM4200-class LF tags into legacy access programmes, and (today) the full NTAG family for NFC-tap consumer products. ICODE SLIX2 covers library and inventory; T5577 covers programmable LF; UHF Gen2 covers asset and supply-chain.
Every inlay is scan-tested 100% before pack — not on a sample. Encoding bureau handles per-tag UID, sector keys, NDEF payloads and any custom commissioning the customer programme needs.
