Penta Security Wallet Card
Our wallet review process
We examine wallets starting at the code level and continue all the way up to the finished app that lives on your device. Provided below is an outline of each of these steps along with security tips for you and general test results.
Application build test result
Penta Security Systems has multiple domains related to their business: pentasecurity.co.kr, pentasecurity.co.jp, and pentasecurity.com. All of these domains host the same product specification sheet which is written in Japanese. Penta Security Systems is Korea-based.
A website described the hardware wallets as an NFC-enabled card and a device. We were not able to locate an actual picture of either, only renderings.
There were also multiple references to a mobile app related to these devices: AMO or D’Amo, Pallet X, or simply Penta Crypto Wallet. Of these, we were only able to locate the application ID of one in Google Play: Penta Security Pallet. Unfortunately, this is no longer available on Google Play.
We were able to translate using Google translate a few features:
- Connection Method: Blue Tooth 4.0, NFC
- User authentication / restore: Fingerprints, PINs, smartphones interlocking, 12-word recovery sheet
- Secure chip: HW Copy Prevention (PUF)
We were unable to locate an actual picture of the card nor is it commercially available. However, the company that provides it, Penta Security Systems is still active. Most smart cards that are labeled as wallets generally have the same flaw: they must be brought on to another system to transact or access the data within them. In this case, the card uses NFC or Blue Tooth to connect to an app that is no longer available. The product description does not indicate a screen or buttons the user can interface with.

Do your own research
In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
