The DynaFlex II Go is a compact, secure card reader designed for mobile and countertop use. It supports modern payment acceptance by enabling merchants to process tap, dip (chip), and swipe transactions with strong built-in security.

Connectivity is provided via USB C or Bluetooth Low Energy (LE), allowing integration across multiple operating systems and platforms. The reader uses MagTek’s MagneSafe® security technology and is certified under PCI PIN Transaction Security (PCI PTS) standards, which are widely used benchmarks for protecting cardholder data during card-present transactions.

The Dynaflex II go supports a wide range of payment methods to meet diverse merchant needs, including:

During normal payment operations, the DynaFlex II Go supports multiple input modes through CSG Forte platforms and custom integrations. 

Supported CSG Forte Integrations 

• Forte Checkout 
• BillPay 
• Forte REST API–based applications 

Typical payment flow: 

1. Application detects the reader and prompts the payer to tap, dip, swipe. 
2. Reader captures payment data and encrypts it according to MagneSafe security rules. 
3. Encrypted data is transmitted to CSG Forte via Forte Checkout, BillPay, or REST API. 
4. CSG Forte processes the request and returns an authorization or decline response. 
5. Application renders receipts or on screen confirmation, following EMV-compliant receipt guidelines where applicable. 

The DynaFlex II Go supports USB‑C for powered, stable countertop connectivity and Bluetooth® Low Energy (LE) for secure wireless mobile operation. 

• USB C, When connected via USB C, the device is powered directly through the cable and supports high reliability wired communication. This option is recommended for fixed or semi fixed environments such as countertops and kiosks. 
• Bluetooth LE, Bluetooth Low Energy (LE) enables wireless operation for mobile use cases. The reader includes an internal rechargeable lithium ion polymer battery, allowing merchants to process transactions without a physical cable while maintaining secure data transmission. 

The DynaFlex II Go hardware design combines clear visual status indicators, intuitive controls, to support secure, efficient, and consistent card-present operations in both countertop and mobile environments. 

• LEDs : The DynaFlex II Go includes four LEDs on the front face that provide visual feedback for device status and transaction state, for example indicating when the reader is ready, actively reading, has encountered an error, or is in a secure state. Detailed LED behavior, including specific patterns and color codes, is documented in the MagTek Installation and Operation Manual 
• Buttons: A single tactile pushbutton is located on the right side of the DynaFlex II Go and is used for device control functions, including initiating specific configuration workflows and performing wake or reset operations. No additional physical controls or switches should be present on the sides of the device; the presence of extra buttons, switches, or openings may indicate tampering and should be investigated before the device is used.

Proper package and device inspection are required to maintain PCI compliance and detect potential tampering.

4. MagTek Wedget (Keyboard Wedge) Configuration(Required for browser based POS integrations) 
   • Install the MagTek Wedget application and corresponding keyboard extension on the host mobile device (Android or iOS). 
   • Enable the Wedget keyboard within the device system settings and set it as the default input method when prompted. 
   • Pair the DynaFlex II Go device with the Wedget application via Bluetooth LE, ensuring the reader is placed in pairing mode and successfully connected. 
   • Configure the Wedget application to use the connected reader as the default device. 
   • Validate that the Wedget keyboard captures encrypted card data and inputs it into the active browser based POS field for processing through CSG Forte 
5. Host Application Configuration 
   • Configure the POS, Forte Checkout, BillPay, or REST API integration to recognize the reader, using the appropriate interface (USB or Bluetooth LE) and device identification parameters. 
6. Initial Test Transactions
   • Execute test transactions (tap, dip, swipe and contactless (Apple Pay/ Google Pay / Samsung Pay)) to validate connectivity, correct data capture, and successful processing through CSG Forte.
