The FuzeCard Problem – EMV Chip Payments and Bank Negotiations

In the past couple years, we’ve seen the coming and going of several smart card companies promising to merge all your credit, debit, and rewards cards into one smart connected wallet. Despite the excitement surrounding all these products, they seem to run into one common wall when it comes to consumer deployment – EMV “Chip” Payments.

Coin and Plastc Shutdown, leaving millions of backers (and their money) out to dry. While Stratos and Swyp seem to be in a perpetual “sign up to get notified” phase. None of the cards have ever successfully supported Chip and Pin or EMV Payments. Why? Because it requires big connections and a large customer base to convince banks to open up their secure chip and pin technology to your ‘smart card’, and, unfortunately, this requires negotiations with each card issuer.

From FuzeCard’s website:

EMV payments require the approval of the card issuer/banks. Fuze’s chip will be compatible from the launch and this feature will be fully available with a future firmware update

As promising as this may sound, it’s not a software problem that Fuze is up against here and no simple firmware update will give the card the EMV support it needs. BrilliantTS will need to first negotiate with big banks, and that’s a tough sell at least 4 companies have failed to do thus far.

Do their promo cards have working EMV chips? According to their Instagram content, no, not yet.

One post from their instagram shows a box of bpay cards from a startup in South Korea. So, what do bpay and FuzeCard have in common? Both appear to be owned by BrilliantTS.

BrilliantTS’s bpay cards appear to have come to the same brickwall for EMV Payments, indicating only “Reserve Now!” for EMV Chip enabled cards.

Noticed the following suspicious startup items on a  friend’s Mac OS X 10.10.5:




The friend had constant McAffe ads in her default browser (Google Chrome).  The computer doesn’t have any recently installed items. The startup items were removed with CCleaner, the computer was updated with the updates available in the app store and restarted. Upon computer restart, Google Chrome indicated “mac search manager” was added. The computer was then updated to the latest version of OSX (macOS Sierra) and restarted.

To update your computer to Sierra, search macOS Sierra in the app store, download, and install. This is a fairly large update so it may take several hours to download and additional time to install.

Recursively Finding (and replacing) All Depreciated

Running the following code from your starting will give you the location of all short open tags in .php extension files. This command recursively searches all directories from the directory you start in.
grep -r --include "*.php" "<?[ ]" .

You may need to modify it if you have .php5 files or other non-php extensions holding php content.

If you’re looking to repalce all of these en-masse, you can do that [very roughly] with the following commands:

replace ALL tags (< ?) with

grep -rl --include "*.php" "<?[^p]" | xargs sed -i 's/<?/<?php/g'

fix any accidently replaced tags that might have happened
grep -rl --include "*.php""<?php" | xargs sed -i 's/<?phpphp/<?php/g'

You should carefully review all replacements done by this code, some php code could break!

Simple Proxmark3 Getting Started Guide on Windows

In the below video, we’ll be scanning a high frequency 13.56 MHZ card (NXP Mifare Classic) and two low frequency 125 kHz cards (HID and EM410x Tag)


  1. First, assemble your proxmark
  2. Download the latest compiled Proxmark3 Software from
  3. Unzip the file contents, and rename the content folder to proxmark3. For the commands following, you should have a folder in your downloads called proxmark3 with the following subfolders: win32, firmware_win, and Windows Driver. If you haven’t already updated your proxmark3 firmware to the latest version, go here.
  4. Open Device Manager to get the COM port of the Proxmark. In this case, it is COM7.
  5. Open Command Prompt (CMD)
  6. Execute the following command to connect to your proxmark3, be sure to replace your COM port with the proper COM port found in Device Manager

    Downloads\proxmark3\win32\proxmark3.exe COM7

  7. You’re now connected to the proxmark3! The following commands will do a low-frequency and high-frequency search for known devices.

    lf search

    hf search

  8. Questions and commends below!

Cards Scanned:

  • T5577 @ 125 kHZ
  • EM410x Tag M1 S50 @ 13.56 MHZ

Proxmark3 #db# Error, Unknown Function

While doing a low frequency search via the command “lf search” on my Elechouse Proxmark3, I encountered the error

#db# Error, unknown function 26

It seems any message prefixed by #db# is a message coming from the proxmark3, rather than the proxmark software running on your computer. This would indicate a bug in the proxmark software!

Solving this bug was relatively simple, just update the firmware!

To do that, check out my guide on proxmark3 firmware updating.

Google Docs Viewer has a couple urls to load documents through. Pagespeed, Pingdom, and Websitegrader tests show the “gview” url performs slightly better.
