BlockChyp uses the Equinox Luxe 6200M device for processing on Mobile3.

Back to Top of Section


Mobile 3 uses the IDTRECH VP3300 for WorldPay mobile credit card processing. For information on the device, refer to: Mobile3 credit card processor: IDTRECH VP3300 for Worldpay 


  • Store brand gift cards will not process on the IDTRECH VP3300.
  • Debit cards will not process on the IDTRECH VP3300 (no input pad on the device to accept signature).
  • The swipe function does not work with Mobile3 (no input pad on the device to accept signature).

Since NETePay is hosted in two ways, through Paladin and through datacap, stores will have to establish a separate WorldPay account and request a merchant ID (MID) from datacap to run NETePay on the mobile device. For information on setting up a Worldpay account, refer to: Worldpay: Dealer Setup Letter (DSL)

Once clients have received their datacap MID, perform the following:

  1. In Paladin, from the main menu, select File > Setup.
  2. Select the Credit Card tab.
  3. In the Credit Cards pane, select Mercury EMV NetEPay Hosted from the Processor list.
  4. In the Mercury EMV NetEPay Hosted pane, enter the Datacap MID in the Datacap MID box.
  5. Click Save.
  6. In the Credit Cards pane, select either Mercury EMV or Mercury EMV E2E from the Processor list.
  7. Click Save, then click Close.

The next step is to pair the IDTRECH VP3300 device to the mobile device 

Pairing IDTRECH VP3300 to the mobile device

  1. Enable the Bluetooth device search function on the mobile host device (smart phone or tablet).
  2. Make sure the VP3300BT is charged or connected to a power source via USB.

Figure 20: Bluetooth function button

The VP3300BT will remain connected to the host indefinitely (via Bluetooth) if powered via a USB cable. If the unit is operating on battery power, the default value is for the unit to enter low-power mode after five seconds of idling and to sleep after 20 seconds of idling to extend battery life. To perform a transaction again, press the Bluetooth function button to re-establish the Bluetooth connection.

To pair the IDTRECH VP3300 device to Mobile3 device:

  2. In the Connections page, turn Bluetooth to On.
  3. Press Scan for available devices.
  4. In the Devices page, select the IDTECH VP3300 device.

  1. Tap Pair.
  2. Open the Settings page and tap WorldPay.
  3. Tap Find Devices.
