# Tangem > The secure hardware and crypto wallet Tangem is a hardware wallet company that lets users store, buy, swap, stake, and spend crypto using NFC-enabled card and ring-shaped devices. Tangem is a hardware wallet company serving individuals who want to hold digital assets without relying on exchanges or custodians. Its products let users store, send, receive, buy, swap, stake, and spend crypto across multiple blockchain networks through NFC-enabled card or ring-shaped devices paired with a companion mobile app. The wallets are aimed at both newcomers seeking a simple setup and experienced holders who want offline key storage. The wallets rely on a secure element chip and require no batteries, cables, or screens, addressing common pain points around hardware wallet complexity and seed phrase exposure. Instead of a single written recovery seed, the system uses a seedless backup model based on multiple physical cards acting as keys, though generating a traditional recovery phrase remains optional. This design is intended to keep private keys offline while still allowing quick tap based transaction signing from a phone. Beyond the flagship card wallet, the lineup includes a ring-shaped wallet and an integrated non-custodial payment card that connects to mobile payment services. The companion app also provides access to buying, swapping, and yield generating features through connected providers, alongside developer and partner programs for resellers and co-branded devices. It is used by retail crypto holders, institutional partners, and businesses seeking custom branded self-custody hardware. - Type: Company - Sector: Custody and Wallets - Status: Active - Founded: 2017-01-01 - Profile: https://thegrid.id/profiles/tangem ## Products - [Tangem Wallet](https://thegrid.id/profiles/tangem): Tangem Wallet is a card-shaped, self-custodial hardware wallet that stores cryptocurrency private keys offline in a secure element chip. Transactions are signed by tapping the card against an NFC-enabled smartphone running the Tangem companion app. The app supports buying, selling, swapping, staking, and earning yield on digital assets across multiple blockchain networks. Key backup is distributed across a two- or three-card set, with optional seed phrase support. The app also provides WalletConnect-based dApp access, NFT management, market tracking, and real-time transaction threat detection. (Hardware Wallet, Live, Main Product) - [Tangem Ring](https://thegrid.id/profiles/tangem): Tangem Ring is a ring-shaped hardware wallet that uses the same certified secure element chip as the Tangem Wallet card. Private keys are generated and stored inside the ring, and transactions are signed by tapping the ring against an NFC-enabled smartphone running the companion app. Each set includes one ring and two backup cards that share distributed key backup, with an optional seed phrase for recovery. The ring is housed in a zirconia ceramic shell rated for water, dust, and pressure resistance and requires no batteries or charging. (Hardware Wallet, Live) - [Tangem Pay](https://thegrid.id/profiles/tangem): Tangem Pay is a non-custodial payment account integrated into the Tangem Wallet app, providing a virtual Visa card for spending cryptocurrency at merchants that accept Visa, including via Apple Pay and Google Pay. Users fund the account with native USDC on the Polygon network, and funds remain on-chain in a smart contract account until a purchase is made, at which point the equivalent USDC is deducted and settled through the Visa network in US dollars. Access requires identity verification, with the account and card kept separate from the main self-custodial wallet. The card program is delivered by a third-party payment service provider and card issuer, with identity verification and transaction monitoring handled by specialized third-party providers.
