Shares your profile
An NFC chip opens your full live contact profile on any modern phone — one tap, no app. The printed QR does the same for a phone without NFC.
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. £45 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 £45, 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.
Not just an access card
It reports back, too
As well as opening the gate, the card shares your profile and lets the person you meet send their details back — every tap and scan logged, no app needed.
Contact-back
Anyone viewing your card can send their name and number straight back — no app, no account. Connections land in your dashboard.
