Card readers & hardware: choosing and wall-mounting a reader

When to use built-in Tap to Pay vs a dedicated Stripe reader, how to pair a WisePOS E in Muin Go, and how to wall-mount a reader beside a tablet.

Muin Go takes card payments two ways, and the right one is a per-device choice you make once in the Pay module under Settings > Card Reader.

When you’d use this

  • You are deciding what to buy before a stall, a counter or a wall station goes up.
  • A mounted tablet keeps missing taps and you want to know whether a reader fixes it.
  • You have a reader in a box and need to know where pairing happens.
  • You are mounting a reader next to a tablet and want it to read as one station.
Tap to Pay (default) External card reader
Hardware None, the phone or tablet’s own NFC A Stripe internet reader: Stripe Reader S710 or BBPOS WisePOS E
Best for Handheld use: events, door-to-door, walking the room Fixed stations: counters, wall-mounted tablets, high daily volume
Customer taps on The back of your device The reader’s own screen
Network The device’s connection Reader’s own WiFi or Ethernet
Cost Free Reader price on Stripe’s hardware page (region-specific)

Rule of thumb: if the device is mounted or does more than a couple dozen taps a day, use a dedicated reader. Phone NFC was designed for handheld use · see Tap to Pay troubleshooting for why mounted devices struggle.

Buying a reader

Order through your Stripe Dashboard’s Hardware shop (dashboard.stripe.com/hardware), which shows the models and current prices for your country. For Muin Go’s external-reader mode, choose a network (WiFi or Ethernet) reader: the Stripe Reader S710 or the BBPOS WisePOS E. During checkout Stripe registers the reader to one of your Terminal locations; if you’re asked to create one, use your venue’s address.

Stripe does not sell a wall-mount reader: every certified reader ships as handheld or countertop. Wall installations use a third-party bracket (next section).

Pairing the reader in Muin Go

  1. Power the reader and connect it to the same network the tablet uses (Ethernet via the included dock, or WiFi from the reader’s settings).
  2. On the device that will use it: Muin Go > the Pay module > Settings > Card Reader. This screen needs full Pay access.
  3. Choose External card reader, then discover readers.
  4. Tap your reader in the list. The pairing survives restarts, and every checkout on this device now sends the customer to the reader’s screen automatically.

To go back to built-in Tap to Pay, open the same screen and either unpair or select This device (Tap to Pay).

Pairing an unattended kiosk is a different door. A tablet running as a kiosk has nobody signed in, so it cannot reach the Pay settings screen. Pair its reader from the kiosk staff panel instead, behind the kiosk PIN and a staff sign-in. It writes the same pairing.

The pairing is held on the device itself, which is why it is a per-device choice and why it does not follow a person from one tablet to another.

One current limitation: the POS cart checkout still uses Tap to Pay on the device itself even in external-reader mode. Every other flow: QuickPay, collect payment, pledges, event tickets, memberships, kiosk POS: uses the external reader.

Wall-mounting a reader next to a tablet

The recommended setup for a wall-mounted tablet station:

Positioning

  • Mount the reader within about 30 cm (12 in) of the tablet, at customer eye level, NFC face toward the customer. The customer should see one station, not two devices to choose between.
  • The tablet runs Muin Go (amount entry, fund selection, receipts); the reader handles the tap on its own screen.

Bracket

  • Use a third-party bracket made for your reader model: search your bracket vendor for the reader’s name. Generic kiosk-mount and VESA-adapter plates also work with the reader’s countertop dock. We deliberately don’t name specific bracket SKUs here; accessory inventory rotates. Budget roughly €30–80 / $30–90.
  • Pick a bracket that leaves the charging/Ethernet port accessible and doesn’t cover the reader’s NFC face (the top half of the front).

Power & network

  • The reader is cable-powered, no battery swaps. Route the power cable (and Ethernet, if used) inside the mount or trunking to the nearest outlet.
  • Prefer Ethernet where available; otherwise make sure the wall position has solid WiFi signal.

After installation

  • Run Reader Check from the Pay module’s settings on the tablet. It verifies the pairing and that the reader is reachable.
  • Watch Payments > Terminals > Reliability in the web app for the first week. A dedicated reader at a fixed station should sit well above a mounted tablet’s own NFC on first-tap success; if it does not, the reader’s network is the thing to look at.

Which setup for which deployment

Deployment Recommendation
Handheld phone at an event Tap to Pay, no reader to buy, made for this
Counter station with a tablet WisePOS E on the counter dock next to the tablet
Wall-mounted tablet WisePOS E wall-mounted beside it via third-party bracket (above)
High-volume fixed counter, no tablet needed WisePOS E standalone: its screen handles the whole interaction
Mounted tablet relying on its own NFC for heavy daily taps Switch it to an external reader

What it affects

  • Every checkout on that one device routes to whichever capture path you chose. Nothing asks mid-payment.
  • Nothing on your other devices. The choice is per device and is held on the device.
  • The Reliability tab under Payments > Terminals, which rolls up tap outcomes per device so you can tell a bad reader from a bad mounting position.
  • Nothing about receipts or deductibility. A gift is a gift and a sale is a sale whichever way the card was read.

When it goes wrong

What you see What it means What to do
No readers appear when you search The reader is not on the same network as the tablet, or it is not powered. Put both on the same network. Prefer the Ethernet dock at a fixed station.
The reader pairs but checkouts still tap on the tablet The POS cart checkout on mobile still uses the device’s own NFC. Every other flow uses the reader. Expected for that one flow.
Card Reader is not in the Pay settings That screen needs full Pay access. Ask an administrator for the permission, or pair from the kiosk staff panel.
The reader is unreachable after a week of working Usually the reader’s WiFi, or a bracket covering the port. Run Reader Check, then check the mount and the cable.
Taps are missed on a mounted tablet with no reader Phone and tablet NFC is designed for handheld use. See Tap to Pay troubleshooting, then fit a reader.
