Bluetooth ConnectivityThe D135 is a wireless PIN pad that pairs over Bluetooth 4.2 (BLE-capable), giving staff a cord-free card-entry device that stays connected to a paired phone, tablet, or countertop terminal.
Compact PIN Pad DesignAt 13 x 67 x 67mm and about 64 grams, the D135 is a pocket-sized standalone PIN pad — a companion device for card entry, not a full POS terminal on its own.
Companion Device for Countertop TerminalsConnects via USB-C or Bluetooth to a phone, tablet, or another CARDZ3N terminal, letting a merchant add a dedicated PIN-entry point next to an existing countertop setup.
PCI-Compliant Card EntrySupports chip and PIN, NFC contactless tap, and optional magnetic stripe entry, and is certified to PCI PTS 5.x SRED alongside EMV Level 1/2 and contactless brand certifications.
NMI Gateway CompatibleThe D135 fits into CARDZ3N's supported gateway stack, so it can be added alongside a merchant's existing NMI-based processing setup without a separate integration project.
Where the D135 Fits
A compact Bluetooth PIN pad is a natural fit anywhere a merchant needs card entry that isn't tied to a fixed countertop position — paired with a phone, tablet, or an existing terminal.
Retail Checkout CompanionA compact Bluetooth PIN pad gives a retail counter a dedicated card-entry point that pairs to a phone, tablet, or existing terminal without adding countertop clutter.Apply Now
Mobile & Curbside PairingBecause it pairs wirelessly over Bluetooth to a phone or tablet, the D135 fits curbside pickup, tableside, or line-busting scenarios where staff need card entry away from a fixed register.Apply Now

Pairs With NMI Virtual TerminalAs a companion PIN pad rather than a standalone POS, the D135 is a fit for merchants running CARDZ3N's NMI-based virtual terminal or gateway setup who need a physical card-entry device to go with it.See NMI Gateway
The PAX D135 is a compact, Bluetooth-wireless PIN pad — a standalone card-entry companion device, not a full POS terminal. It pairs to a phone, tablet, or another terminal, and is positioned by PAX for micro and small merchants, fashion & retail, and food & beverage settings.
What the D135 Is (and Isn't)
The D135 is the smallest device in CARDZ3N's terminal lineup: a wireless, Bluetooth-paired PIN pad, documented in both a PAX-authored datasheet and a CARDZ3N-branded quick setup guide. It's built around chip and PIN, NFC contactless, and optional magnetic-stripe entry — there's no built-in printer, camera, or standalone menu system, because the D135 is meant to pair with something else (a phone, tablet, or another terminal), not run on its own.
PAX markets the D135 as a "Classic" line CONTACTLESS mPOS device, "pocket sized" and "powered by Monitor" (PAX's proprietary OS), aimed at micro and small merchants, fashion & retail, and food & beverage. At roughly 63.6 grams and 13 x 67 x 67mm, it's designed to disappear into a pocket or apron between uses — the opposite design goal of a full countertop terminal like the PAX A80.

Pairing & Card Entry
Powering on the D135 is a single button hold until it beeps; holding it again until all four colored lights flash simultaneously powers it down. To pair over Bluetooth, power the device on, scan for "PAX D135_XXXX" (the last four characters of its MAC address) from the host phone or tablet, and pair, entering a passkey if prompted. A USB-C cable is included for a wired connection instead, if preferred. Once connected, card entry supports three methods: swipe (magnetic stripe, either direction, stripe facing the device body), dip (chip card, metallic contacts up and facing the device), and tap (contactless, held within about an inch of the indicated area).
Where It Fits
Because the D135 is a companion device rather than a full terminal, it's best thought of as an add-on to an existing setup: a retail counter that wants dedicated PIN entry without crowding a countertop terminal, a curbside or tableside pairing with a phone or tablet, or a small service counter where a full Android POS terminal would be overkill.
The D135 runs on CARDZ3N's supported gateway stack, including NMI, so it can be added to an existing CARDZ3N processing setup without a separate integration project.
What's Documented and What Isn't
CARDZ3N's source material on the D135 is thinner than on the Valor countertop and POS terminals: a two-page PAX datasheet, a PAX marketing sheet, and a CARDZ3N-branded quick setup guide covering power, pairing, and card-entry mechanics. There is no PAX-authored transaction-flow QRG for the D135 the way there is for the A80 — because the D135 is a companion card-entry device, not a standalone terminal with its own menu system, it doesn't run its own Sale/Void/Refund flow independent of whatever host device or terminal it's paired to.
What is confirmed, directly from the source material: full physical specs (processor, memory, battery, dimensions, weight), the certification list above, power and pairing steps, and the three card-entry methods covered in the section above. We'd rather tell you exactly what's documented than guess at a transaction menu that doesn't apply here — ask your CARDZ3N rep for the latest confirmed detail before ordering.
Pricing
The PAX D135 is available through CARDZ3N with pricing quoted per merchant based on volume and equipment needs — CARDZ3N is the sole quoting and selling party, never a pass-through to PAX's own pricing. Ask your CARDZ3N rep for current pricing.
