What Is The DynaFlex II Go?

The DynaFlex II Go is Arryved’s latest EMV card reader that offers tap, dip, swipe, and digital wallets all in one! The DynaFlex is exclusive to Arryved Pay, our end-to-end payment solution with in-house payment processing. Use this guide to set up your new DynaFlex II Go card reader with Bluetooth pairing and mounting.

Prerequisites

• Use this guide once you’ve received your new DynaFlex II Go card readers. Have them fully charged and the mounting pieces handy. 

• Grab the POS devices you want to pair with your new card readers. 

• You must update Arryved Service to version 2.13 or higher on all your POS devices with a DynaFlex II Go card reader. You’ll want to keep Arryved Service up to date at all times to ensure you’re operating with the latest improvements. 

Limitations

• Treat your DynaFlex with care. Be careful not to drop, hit, or shake the reader. If it endures too much physical damage, it may go into Tamper Mode and will need to be swapped out for a new one. 

• If you’ve opted out of Preauthorization with Arryved, your card reader may not be able to detect expired cards or start a tab with digital wallets.

• Digital wallets will not grab the cardholder’s name when starting a tab. A Tab Name will need to be manually entered or a Table Number selected. 

• If the POS device is offline or in Offline Mode, it will not grab the cardholder’s name when starting a tab. Offline Mode also can’t detect expired cards. 

• The DynaFlex II Go doesn’t support gift cards with Track 1 data. Track 2 is supported. You won't need to worry if you’ve purchased gift cards from one of our recommended suppliers (eCard Systems or 4ics). 

• Do not mount the card reader to the POS device directly. Mount the provided clip so you can attach and remove the card reader at any time to set it aside for charging or to view the serial number on the back of it. The serial number is needed for pairing. 
  

Setup Guide

Steps To Follow

1. Remove old card readers (if needed)

2. Mount the DynaFlex II Go to your POS device

3. Pair the DynaFlex II Go with your POS device

Step 1: Remove Old Card Readers

If you’re swapping out old card readers with the new DynaFlex II Go, you must first remove the old ones that are currently mounted to your POS devices. 

1. Grab the POS devices you want to pair with your new card readers.  

2. For any easily detachable card readers and koozies, go ahead and remove those first.

3. For koozies that are attached with sticky tape, twist them to detach. Don’t pull!

• Pro Tip! Try sliding a piece of floss back and forth in between the koozie and POS device to detach the sticky tape. 

• Use Isopropyl or alcohol wipes to remove any sticky residue. A clean surface is necessary to attach the new reader. 

Step 2: Mount The DynaFlex II Go

Stand-Alone

The new DynaFlex II Go card readers can live in a stand-alone dock and be placed on any surface. It’s able to transact while in the dock and be removed from the clip when needed. 

Attached To The POS Device

If you want the card reader to be directly mounted to your POS device, attach the clip with sticky tape:

1. Find the perfect spot for the clip on your tablet, handheld, or foam case.

• See the image examples below for the best placement. Make sure the card dip/swipe ports aren’t blocked by anything, and the card will have room to be inserted or swiped. 

• On a handheld device, you’ll probably want the dip/swipe ports to face downward so the card can be inserted from the bottom of the device. 

• On a tablet stand or foam case, the dip/swipe ports should be facing upward so the card can be inserted from the top of the device. 

2. Be sure the surface area is clean. Use alcohol wipes to remove residue, dust, and oils. 

3. Remove the backing of the sticky tape and apply it to the back of the mounting clip. 

4. Make sure the outer edge of the clip is facing in the correct direction so that tap, dip, swipe, and the charging port are accessible (see image examples below). Press the clip into the POS device. Hold for 30 seconds. 

5. Wait 24 hours before applying weight to the clip for maximum hold. 

6. After 24 hours, pop the reader into the clip. Be sure the charging port and the tap, dip, and swipe ports are positioned correctly. 

Step 3: Pair The DynaFlex II Go

You can have the DynaFlex II Go card reader paired via Bluetooth or connected via USB-C cable. We strongly encourage you to use the cable that was provided to you for maximum compatibility and stronger connections. 

1. IMPORTANT! Tablets must be paired to the DynaFlex with a USB-C cable. Bluetooth pairing is only available to handheld POS devices at this time.
   

USB-C PAIRING

1. Grab the USB-C cable and attach one end to the card reader and the other end to the POS tablet or handhe. This will speed up the connection and keep the battery levels strong. 

2. Open Arryved Service and log in. 

3. Tap STAFF.

4. Tap Settings.

5. Tap the Reader button.

6. Select the “MagTek USB DynaFlex II Go”. 

7. A confirmation modal will appear at the bottom of the screen. Click OK to confirm the pairing.
   

BLUETOOTH PAIRING

If you want to pair the card reader via Bluetooth, you must first pair it in your Android Settings, then pair it in Arryved Service. 

1. IMPORTANT! The steps below can be used to pair your DynaFlex to a handheld device. Tablets must be paired via USB-C. Furthermore, if your handheld device is running on Android 15 (the latest OS), use these steps instead. Pair Your Card Reader To Android 15.

1. Open the Android Settings on your POS device, it'll appear as a grey gear icon on your tablet/handheld device. 

2. Tap Connections at the top of the list. 

3. Tap Bluetooth. 

4. Make sure the toggle switch next to the word Bluetooth is toggled ON and appears blue.

5. Press and hold the pushbutton on the side of the reader until you hear 4 beeps. LED #4 will start flashing once the reader is ready to be paired. 

• IMPORTANT! Holding the pushbutton for two beeps will power the reader off. Make sure you keep holding until you hear 4 beeps or see the 4th LED flash. 

6. From the Bluetooth settings on the POS device, find your card reader. 

• It’ll appear as ‘DF II Go - B[Serial #]’ followed by the serial number.

• You can check the serial number by looking at the back of the reader, and find the number next to ”SN…”. 

7. When prompted for a PIN, type in ‘000000’ (six zeros).
