Accessories — Other

Small accessories that keep a Square setup connected, marked, and ready to serve

Square’s U.S. “Other” accessory group covers the practical pieces that are easy to overlook when you are building a counter or mobile checkout: a Square Terminal hub for wired networking, USB-C and micro-USB extension cables, a replacement impact-printer ribbon, and small marketing kits for contactless, Afterpay, and Bitcoin acceptance.

How it fits your business

The group also includes a USB-to-Ethernet adapter for Square Stand (2nd generation). These are add-ons, not a replacement for a POS device or payment account. Pick by the exact Square hardware generation and the job you need done, then confirm the compatibility list before ordering. Prices and availability shown here were checked on October 27, 2026.

Key capabilities

What you can do

Solve the last connection gap
The $49 Hub for Square Terminal adds the connection point Square documents for Ethernet setup. A USB-to-Ethernet adapter is listed for Square Stand (2nd generation) at $39, while the 6.5-foot extension cables help place compatible equipment where the counter layout needs it.
Keep existing print workflows running
The $9 Impact Printer Ribbon is listed for the Star SP742 Impact Printer. It is a consumable replacement, not a printer, so it only makes sense if that supported printer is already part of the setup.
Make a counter easier to deploy
The $15 USB-C extension cable for Square Reader (2nd generation) and the $12 extended customer-display cable for Square Register can give a configured station more placement flexibility, but each cable is tied to the named hardware rather than being a universal Square cable.
Support customer-facing payment messaging
Square lists free Credit Card, Contactless Payment, Afterpay, and Bitcoin marketing kits. They are printed signage and table materials, not payment features or a substitute for enabling the relevant service in Square.
Avoid a generation mismatch
Square says hardware has multiple generations and versions and directs sellers to its compatibility tools. Confirm the exact device before buying; for example, Register customer displays are not cross-compatible between generations and versions, and older Terminal/Register v1 hardware no longer receives software updates after September 1, 2025.

Setup and compatibility limits

A Square account is required to sign in and use Square hardware. Square’s setup guidance says Terminal and Register need Wi-Fi or Ethernet, cannot use captive-portal networks, and should be used in the country for which the hardware was approved; U.S.-intended hardware is not approved for use outside the U.S. Square recommends checking the accessory compatibility page with the specific Square hardware selected before purchase.

Software and payment costs are separate

These accessories do not create a separate subscription. Square Point of Sale has a free plan, while Plus and Premium and legacy vertical plans can have subscription charges. Processing is separate from accessory purchase: Square’s U.S. fee page lists Square Free in-person tap, dip, or swipe at 2.6% + $0.15 per transaction, Square Plus at 2.5% + $0.15, and Square Premium at 2.4% + $0.15; the applicable rate depends on the seller’s plan and payment type.

Requirements

Square account and login credentials for Square hardware use.
Select the exact Square hardware and verify accessory compatibility before ordering.
For Terminal or Register networked operation, Wi-Fi or Ethernet is required; captive-portal networks are not supported.
Use U.S.-approved hardware in the United States; country approval is not transferable.
Some items only work with the named device, printer, generation, or connector.
Processing fees and any POS subscription are separate from accessory pricing.

Category pricing and product availability were verified on the official Square U.S. Shop page on 2026-10-27 and may change.

The category has no single hardware price, so hardwareUSD is null rather than implying one price applies to every item.

Free marketing kits are listed at $0, but availability and any checkout eligibility should be confirmed at purchase.

Compatibility is model- and generation-specific; use Square’s compatibility tool before buying cables, hubs, or replacement parts.

Square’s published processing rates vary by plan, payment channel, and seller circumstances; this record does not estimate a seller’s total cost.

No image is included because the category page does not provide license evidence for third-party product photography.

Questions

Frequently asked questions

Is Accessories — Other a Square subscription or software plan?

No. It is a Shop category for add-on hardware, cables, replacement parts, and printed marketing kits. Square account, POS software, plan charges, and payment processing are separate.

Can I use any USB or Ethernet cable with these accessories?

Do not assume that. Square names specific devices and generations for several items, including the Square Reader (2nd generation), Square Register customer display, Square Stand (Mount), and Square Terminal. Check the official accessory compatibility page for the exact hardware before ordering.

What does the Hub for Square Terminal do?

Square’s U.S. Terminal setup instructions identify the hub as the accessory needed when connecting Terminal by Ethernet. Terminal can also connect by Wi-Fi, but captive-portal networks are not supported.
