Shares your profile
An NFC chip opens your full live contact profile on any modern phone — one tap, no app.
Dual-chip access card
Your business card opens the gate.
One card, two chips: an NFC chip that shares your live profile, and a separate MIFARE credential that opens a compatible gate, door or barrier. £39 one-off with six months of Pro included — built for marinas, yards and sites.
What you get
Two jobs, one card
Opens the gate
A separate MIFARE access credential lets the same card work on a compatible gate, door or barrier.
One thing to carry
Your business card and your site pass in a single card — no second fob on the lanyard.
Made for sites
Built for marinas, yards and sites. Order singles at £39, or 10+ as a quoted site rollout.
Technical specifications
Exactly what's inside
- NFC / profile chip
- NXP NTAG213 — 13.56 MHz, ISO/IEC 14443A, NDEF. Encoded with your Universal Contacts tap link; carries a 7-byte UID.
- Access credential
- A separate MIFARE chip — supplied as MIFARE Classic 1K or DESFire to match your reader. This is the credential your access system reads.
- Frequency
- Both chips are high-frequency 13.56 MHz. The card does not work with 125 kHz low-frequency proximity systems (e.g. EM4100 or HID Prox).
- Access UID
- Depends on the MIFARE type — typically a 4-byte UID on Classic 1K or a 7-byte UID on DESFire. Confirm which your system expects.
- Enrolment
- The access credential must be enrolled into your access-control system by your provider. The two chips operate independently — programming one never affects the other.
Check compatibility before you order. Access-control systems vary. Before buying, confirm with your access-control provider that they read 13.56 MHz MIFARE and can enrol a new credential — and, for a site, that they'll enrol these cards. For 10 or more, order via quote so we can match the MIFARE type to your system. Full detail is in our Terms: we don't warrant access-control compatibility with hardware we haven't tested.
