Grandstream GDS37XX NFC Card (G-AC1) 10-Pack

A ten-pack of G-AC1 NFC access cards for the Grandstream GDS37XX door entry range — credentials to issue to staff, residents or contractors.

Match the credential type to your reader before ordering. The GDS37XX readers work with both 125 kHz and 13.56 MHz credentials, and Grandstream sells more than one card type — G-AC1 and G-AD2 are not interchangeable. If you already have cards in circulation, the new ones must be the same type or they simply will not be read. If you are unsure which you have, send us one and we will identify it rather than guess.

Buying in tens is how access control is normally run: a pack on the shelf covers new starters, replacements for lost cards and the spares that any site with a door system ends up needing. A GDS37XX door station holds up to 5,000 credentials on the device itself, so there is no practical limit on issuing them.

Before you order

• Cards and fobs are separate items — both come in ten-packs
• Credentials are held on the door station — up to 5,000, no server required
• Send us a sample if you are unsure — we would rather identify it than have you order twice

Frequently asked questions

What is the difference between G-AC1 and G-AD2?

They are different credential types and they are not interchangeable. Which one you need depends on what your door station and existing cards use. If you have cards in circulation already, order the same type — and if you do not know which that is, send us one.

Will these work with my existing reader?

They are made for the Grandstream GDS37XX range. For a non-Grandstream reader, or a mixed estate, check with us first — card compatibility is decided by the chip, not by the shape.

How many credentials can the door station hold?

Up to 5,000, stored on the device rather than on a server — so entry keeps working even if the network is down.

Can I mix cards and fobs?

Yes, provided both are the credential type your reader uses. Cards suit lanyards and wallets; fobs suit keyrings. Most sites issue a mix.

Are they pre-programmed?

Credentials are enrolled against your door station when you issue them, so a lost card is removed from the system rather than remaining valid. Ask us if you want help with the enrolment process.

Can I order more than ten?

Yes — order multiple packs. Tell us how many you need and we will check stock before you commit.
