When it comes to cryptocurrency there are 2 choices when it comes to wallets. You have hot wallets and cold wallets. Hot wallets connect to the internet in order at access your crypto while cold wallets keep your private keys offline. Hot wallets are much easier to deal with but the fact that they are connected to the internet makes them prone to attacks by hackers. A simple Google search will show you just how often these attacks occur; yes… even with the big exchanges.

I own several cold wallets for different reasons. Cold wallets are unique in a way that not all cold wallets work with the same cryptocurrencies. This is also true when it comes to hot wallets. So I have different wallets in order for me to have access to all of the crypto that I currently own.

I began traveling again due to Covid restrictions being lifted. Even when traveling internationally, more and more businesses are accepting crypto for payment on goods and services. Most cold wallets that I own are bulky and require additional hardware and cables in order for me to access my crypto. I recently came across the AT.WALLET by AuthenTrend and liked what I read about it. What really attracted me was it’s size as well as its ability to work with both Bluetooth and USB as far as its operation. It can easily fit in my regular wallet and is durable as well as waterproof.

I ordered my AT.WALLET and as soon as it arrived I unboxed it and began the setup. I scanned the code in the manual in order to download the app. I paired the AT.WALLET via BT to my phone and follow the simple online instructions. In order to access the AT.WALLET you need to use your fingerprint. This makes things simple and more secure. I setup my fingerprint by following the step by step info in the app and was up and running within a few minutes. I added the 2 main tokens that I use while traveling which are BTC and ETH and I was ready to transact.


  • FINGERPRINT LOGIN: complicated PIN code is noisy to input for Wallet login, simple PIN code causes concerns for hacker. Fingerprint is the solution to replace PIN code since it is always with you, never forget and not easy to be copied, touch for fingerprint verification to login & do transactions.
  • SECURITY by EAL 5+ SE (Secure Element): Designed with Infineon Secure Element keeps private keys always offline without hacking concerns, private key never leaves SE and sign transaction hash data inside SE.
  • BIOMETRICS CARD TYPE DESIGN: easy to carry, put AT.Wallet into your pocket or wallet to go; IP68 certified is the highest IP rating for both Dust Tight and Water Resistance up to 1.5m deep; built-in E-INK display can display QR code and Wallet information as standalone mode – query and receive cryptocurrency without app connections.
  • EASY TO USE: iOS, Android app can work with AT.Wallet via Bluetooth, Mac can work with AT.Wallet via both USB and Bluetooth; battery charging via USB docking.
  • SUPPORTED CURRENCIES: AT.Wallet supports Bitcoin, Ethereum, Bitcoin Cash, Litecoin, Dogecoin, XRP, Dash and ERC20 Tokens, Changely, WalletConnect, NFT via WalletConnect; more cryptocurrencies support later by firmware and app upgrade.

I had a few questions for Authentrend about their AT.WALLET that I generally get asked by my subscribers. I posed those questions to the team over at Authentrend and below is their response to those questions.

My Q&A With The AuthenTrend Team About The AT.WALLET:

Q: Can we have multiple AT.Wallet devices using the same wallet/ account? I can leave a wallet in 1 location and a duplicate in another location, but they both contain the same info/account/keys?

[AT] You can use the same Mnemonic Phrase to recover wallet/account on multiple AT.Wallets Card, the keys will be exactly the same between all AT.Wallets. Only some transaction history cannot be synced because it may not on the blockchain or cannot be recognized.

Q: Is there any way to trace transactions by governments? From Binance/ Coinbase/ PayPal, does the government know it’s in your AT.Wallet cold wallet now, as opposed to somewhere else? Example… I transfer from Coinbase to AT.Wallet, once it is out of Coinbase, can anyone find out or trace where it went from there?

[AT] AT.Wallet is non-custodial wallet, no need to do KYC. Therefore, we don’t know that who owns an AT.Wallet, but the government can trace transactions via any CEX that you ever did KYC for it.

Q: Does upgrading the firmware wipe out the AT.Wallet?

[AT] no, it won’t wipe it, just upgrade new features or bugs fixing; but if fingerprint matching continuous 10 times fail, it will reset AT.Wallet (to factory state, same as wipe).

Q: If I buy an AT.Wallet, how do I know the company wouldn’t have access to get into my cold wallet and do what they want with it? AT.Wallet is a new wallet to the market, how can we be 100% sure that we can trust them to not have some type of -BACKDOOR-to access my wallet in the future?

[AT] we don’t have 3rd party certification yet, we just can describe what we have: (1) AT.Wallet card alone is not online, only connect to app to online; (2) any login and transactions need fingerprint matching, nothing can happen if fingerprint is not matched. (3) OTA firmware encrypted and only decrypt by unique key inside the card (Hardware chipset). (4) the product is CES award for security and privacy category.

Q: Any recommendations to back up key files for the AT.Wallet?

[AT] Only mnemonic phrase. Private keys cannot leave AT.Wallet.

Q: Is an RFID blocker needed for this device?

[AT] AT.Wallet doesn’t use RFID technology.

Q: Can the At.Wallet be wiped out during x-rays at airports or other screeners? We hear the horrors of privacy invasion on cell phones when they are turned on at airports. How are we protected from this?

[AT] No, but x-rays can damage any chips with extreme high power.

Q: Do you have any weatherproof protective case recommendations for those with active/adventurous lifestyles? Hikers/backpackers, international travel? There are cables, adapters; what are the ideal travel cases if any?

[AT] AT.Wallet is IP68 validated.

Q: Why not USB C? More components to now carry and misplace by going with micro USB. I need an adapter for my phone and I have to use the docking station on my new MBP, just to connect to the AT.Wallet.

[AT] since it’s on docking, we may change it later; we design it from 2018/2019, USB-C is not popular yet, another thing is thickness, micro-USB is thin enough(compared with USB-C)

Q: Is it possible to buy/sell/swap crypto within the AT.Wallet?

[AT] it can do transaction via app including “Send” “receive” and “swap by Changlly”, but not supporting buy/sell directly.

Q: Do I need to close the App or take any other precautions before I unplug the At.Wallet from the cable and device?

[AT] no, except it’s under transaction or syncing via USB (Mac), the major application is Bluetooth (iOS/Android/Mac); in addition, after logging in, only making transactions needs AT.Wallet. App will prompt users to connect with AT.Wallet if not connected.
