Kem Infinity Card

A crypto card offering 300% cashback in cryptocurrency with absolutely zero annual fees and no staking requirement sounds almost too good to be true. The Kem Infinity Card, issued by Kemfinity s.r.o. and running on the Mastercard network, is one of the boldest propositions in the European crypto card market right now. But bold claims demand scrutiny — especially when the card carries a trust score of just 26 out of 100. In this independent review, we break down everything you need to know before applying.

Overview of the Kem Infinity Card

The Kem Infinity Card is issued by Kemfinity s.r.o., a company operating under European jurisdiction. The card runs on the Mastercard network, which means it benefits from near-universal merchant acceptance across Europe and globally. It is available both in France and across the broader European Union, making it accessible to a wide audience of crypto enthusiasts looking for everyday spending utility.

Kemfinity s.r.o. is a relatively new entrant in the crypto card space. Unlike established players such as Crypto.com, Binance, or Coinbase, the company has limited public history and minimal third-party coverage — a fact that directly influences its trust score of 26/100 on our platform. While a low score does not automatically mean a product is fraudulent or unreliable, it does signal that due diligence is especially important before committing to this card.

The card is positioned as a global, fee-free crypto spending tool, with its three main feature tags being: global, no_fees, and cashback. On paper, it targets a broad audience — from occasional crypto spenders to active daily users.

Cashback and Rewards

The headline figure for the Kem Infinity Card is its staggering 300% cashback rate in cryptocurrency. This is, by a significant margin, the highest advertised cashback rate we have seen on any crypto card reviewed on topcryptocards.eu. For context, leading cards from Crypto.com or Nexo typically offer between 1% and 8% cashback under standard or premium tiers.

However, that exceptional number demands a very careful reading of the fine print. Extreme cashback rates of this magnitude are almost always conditional — whether tied to specific merchant categories, introductory periods, spending caps, or promotional mechanics. At the time of this review, detailed and transparent documentation on exactly how the 300% cashback is calculated, which cryptocurrencies are distributed, and what spending thresholds or caps apply was not readily available in clear public-facing terms.

What we can confirm is that no staking is required to access the cashback — a genuine differentiator from competitors like Crypto.com's Visa card, where staking CRO tokens is mandatory to unlock higher reward tiers. This removes a barrier for users who do not want to lock capital in a staking contract.

Our recommendation: before activating the card, request explicit written documentation of the cashback structure, including maximum monthly reward caps, eligible transaction types, and the specific cryptocurrencies you will receive as rewards.

Fees and Conditions

From a fee perspective, the Kem Infinity Card presents an attractive and simple structure:

• Annual fee: €0 — completely free to hold
• Staking requirement: None — no locked capital required
• Network: Mastercard — widely accepted globally

The absence of an annual fee and staking requirement is genuinely appealing, particularly for budget-conscious users or those who are new to crypto cards. Most competitive crypto cards either charge an annual fee or require significant token staking (sometimes thousands of euros worth) to unlock meaningful benefits.

That said, the publicly available information on other potential fees is limited. Key cost areas to investigate before signing up include: foreign transaction fees, ATM withdrawal limits and associated charges, card loading fees, currency conversion spreads, and inactivity fees. The lack of transparent, publicly available fee schedules is a concern that aligns with the card's low trust score.

Who Is This Card For?

Despite the trust score reservations, there are specific profiles for whom the Kem Infinity Card may be worth investigating:

• Risk-tolerant early adopters who enjoy testing new fintech products and are comfortable with limited issuer history
• EU and French residents looking for a no-cost entry point into crypto cashback cards without staking commitments
• Light spenders who want to experiment with a crypto card without any financial commitment (given the €0 annual fee)
• Crypto-curious users who want Mastercard acceptance globally without locking funds in a staking pool

It is not recommended as a primary financial card for users who rely on clear, stable terms, strong customer support infrastructure, and well-documented issuer credentials. For those users, established alternatives offer far greater peace of mind.

Advantages

• Zero annual fee — genuinely free to hold and use
• No staking requirement — access rewards without locking capital
• Mastercard network — global acceptance at millions of merchants
• Available in France and across the EU — broad geographic eligibility
• Advertised 300% cashback — potentially the highest cashback rate on the market if terms are favorable
• No foreign transaction fees advertised — useful for international travelers

Disadvantages

• Trust score of 26/100 — one of the lowest on our platform, signaling limited verifiable credibility
• Kemfinity s.r.o. is a relatively unknown issuer — limited public track record, reviews, or regulatory transparency
• 300% cashback claim lacks clear public documentation — conditions, caps, and eligible cryptos are not transparently published
• No publicly available detailed fee schedule — ATM, FX, and loading fees are unclear
• Limited customer support infrastructure visible online — a concern for dispute resolution
• Potential regulatory uncertainty — newer issuers may face compliance challenges in the evolving EU crypto regulatory landscape (MiCA)

Our Verdict

The Kem Infinity Card is a high-risk, high-curiosity proposition. Its zero-fee, no-staking model addresses real pain points in the crypto card market, and the Mastercard network integration gives it practical usability. But the 26/100 trust score is not a number we can gloss over — it reflects a lack of verifiable issuer transparency, limited public documentation, and minimal independent third-party validation.

The 300% cashback headline is eye-catching, but without crystal-clear terms, it risks being a marketing figure rather than a realistic, everyday reward. We advise extreme caution. If you choose to try this card, treat it as a secondary card only — never load it with funds you cannot afford to lose, and thoroughly verify all terms directly with Kemfinity before use. For users prioritizing security and reliability, established alternatives with higher trust scores remain the safer choice.

Our implicit rating: 2.5 / 5 — Interesting concept, but trust and transparency must improve significantly before we can recommend it with confidence.
