Figure & Design

Currently, Ledger Nano S  is one of hardware wallets and its popularity is quite high in the hardware wallet market. Although its design is simple as USB Thumbdrive, but in term of worthiness, in my opinion  it is remarkable product. Ledger is a hardware wallet manufacturer which has been high level of reputation for a long time. Because of its price is quite reasonable, not overvalued. In term of its performance, it looks very good with comprehensive functions, with OLED display screen showing in single row and 2 buttons on the left and right. Ledger logo is screened in the front and vires in numeris” which means “Strength in numbers” is also screened in the back

In my opinion , the design of Ledger Nano S  is quite simple, not outstanding because of its similarity to USB Thumbdrive. However, its design is portable but small display screen. The buttons is quite easy user to press because they are not embedded in the hardware like Trezor

Product Package

Fundamentally, the main target of this product is for the user who concern about the security for storing digital currency. User expectation to hardware wallet is to receive the genuine product from manufacturer is one of the key issue that every manufacturers have to concern. That’s why Ledger, the company has different way to do the product packaging. Generally, other hardware wallet manufacturer always use a  “Temper Proof Lable Stricker” which is hard to counterfeit. It will be attracted at entry side of the package in order to confirm when anyone attempt to open the packet and install malicious firmwares, so that it is clearly noticeable for user. In another way, Ledger do not use this sticker way of protection, the package is just a normal plastic cover but what Ledger uses is device’s software to detect and proof the integrity whether the firmware has been  exploited or modified. This is the reason that can confirm whoever decide to choose Ledger will not get any effects , even though there is no sticker attracted ( Temper Proof Lable Stricker)


Inside the package  consist of this following


  1. Ledger Nano S Wallet
  2. Micro USB Cable
  3. Connector
  4. Neck strap
  5. Cable for keychain
  6. Getting Started and Product Manual

Instruction of Fido U2F (Universal Second Factor) or  2FA (Two Factor Authentication)


Fido U2F is  open standard authentication which is initially developed by Yobico and Google but, lastly they established Fido Alliance as supported organisation. In my view, providing  U2F authentication is considered as very useful feature because authentication by hardware is safer than Google authenticator by Token with Google Authenticator
