DCENT S and Tangem represent two competing approaches in the card-shaped hardware crypto wallet market, both utilizing EAL6+ certified secure elements but differing fundamentally in backup and recovery systems. DCENT S launched in July 2026 from South Korean company IOTRUST, while Switzerland-based Tangem has operated in the market for a longer period. The wallets use NFC technology to enable tap-to-sign transactions without cables, batteries, or Bluetooth pairing. The core distinction lies in backup architecture: DCENT S pairs each primary card with a dedicated R3covery Card that cannot sign transactions, while Tangem sells sets of two or three identical cards where each card functions as both primary wallet and backup. Both wallets fit credit-card dimensions, support major blockchain networks including Bitcoin, Ethereum, XRP, and Solana, and operate through mobile apps on NFC-enabled Android and iOS devices.
DCENT S and Tangem Share Card Form Factor and Durability Ratings
Both wallets measure approximately 85.6 by 54 millimeters. DCENT S measures 0.9 millimeters thick. Tangem offers an additional wearable ring form factor not available from DCENT. DCENT S carries an IP69 dust and water resistance rating, while Tangem features IP69K rating. Tangem advertises resistance to X-rays, electrostatic discharge, and electromagnetic pulses. DCENT S operates from minus 30 to plus 50 degrees Celsius, while Tangem functions from minus 25 to plus 50 degrees Celsius. Tangem provides a 25-year hardware warranty, while DCENT S offers a limited lifetime warranty.
Both Wallets Use EAL6+ Secure Elements with On-Device Key Generation
DCENT S and Tangem both use EAL6+ certified secure elements, the same certification level used for government IDs, passports, and EMV payment cards. The secure element generates private keys on-device during setup. The private key never leaves the chip, never touches the smartphone, and never gets stored on company servers. Both wallets are battery-free and receive power entirely from the phone's NFC field during signing sessions. Tangem includes anti-counterfeit verification through their app. Tangem received independent firmware audits from Kudelski Security in 2018 and Riscure in 2023. DCENT S has not published equivalent third-party audit results. Both wallets lock after repeated incorrect PIN entries and include tamper protection that locks the card if physical chip extraction is attempted.
DCENT S Uses Dedicated R3covery Card While Tangem Provides Multi-Card Sets
DCENT S includes two cards in every box: the primary DCENT S card for transactions and a dedicated R3covery Card. The R3covery Card cannot sign transactions and serves only to restore the wallet if the primary card is lost. The backup is stored inside an EAL6+ secure chip, with recovery data never displayed as words or written on paper. Tangem sells wallet sets containing two or three identical cards or combinations of cards and a ring. During setup, the private key is securely copied to all devices in the set. Any card in a Tangem set can function as the primary wallet. With Tangem, every card in the set can sign transactions. With DCENT S, the recovery card cannot sign transactions even if stolen without the main card and PIN.
DCENT S Supports 100+ Blockchains with XRP Ledger Focus
DCENT S supports over 100 blockchain networks and more than 4,900 tokens. Tangem supports more than 90 blockchain networks and over 14,000 tokens. Both wallets support Bitcoin, Ethereum, XRP, Solana, Stellar, Polygon, and BNB Chain. New chains are added through app updates on both platforms without requiring physical card firmware updates. DCENT S has worked with the XRP Ledger since 2018 and supports Trust Lines, decentralized applications, swaps, sending, receiving, and holding XRP. Tangem supports XRP but does not emphasize XRPL functionality in marketing materials.
Both Wallets Enable NFC Tap-to-Sign Workflow Through Mobile Apps
Tangem claims a two-minute setup time, while DCENT S estimates three minutes. Both wallets require an NFC-enabled Android or iPhone. Users download the app, tap the card, create a PIN, and can send and receive crypto. Daily transactions involve opening the app, creating a transaction, tapping the card against the phone, waiting approximately one second for signing completion, and broadcasting the transaction. Neither wallet includes a display, requiring users to verify transaction details in the app before signing. The DCENT app and Tangem app both support sending and receiving crypto, portfolio viewing, and transaction history tracking. Both apps are available for Android and iOS. Tangem's app offers built-in swapping through integrated providers, staking support for certain assets, and decentralized application connectivity. DCENT's app supports swapping, portfolio tracking, and basic wallet functions.
DCENT S Includes R3covery Card While Tangem Sells Multi-Card Sets
Tangem offers two-card and three-card sets, with the ring version priced higher than card versions. DCENT S comes as a single primary card plus the R3covery Card in every box. DCENT S launched with free U.S. shipping, delivered duty paid, a 30-day money-back guarantee, and a limited lifetime warranty. Tangem offers similar shipping options with a 25-year standard warranty. With Tangem, users pay for multiple working cards upfront. With DCENT S, users receive one working card and one recovery-only card, requiring a replacement purchase if the primary card is lost.
