Crypto Payments in Retail: The 2025 Guide to Web3 Point-of-Sale

The Last Mile of Crypto Adoption

For years, the dream of buying coffee or other day-to-day essentials with crypto has been just that, a dream. Early attempts were slow, clumsy, and expensive. But in 2025, a new generation of Web3 point-of-sale systems is finally making crypto payments in retail a reality. What does this future look like?

While cryptocurrency has made tremendous headway in trading, investing, and online payments, its use in everyday, in-person spending remains limited. The gap between on-chain or online crypto activity and real-world spending is often referred to as a last-mile problem.

Interacting with on-chain activities such as buying, selling, and transferring cryptocurrency on exchanges or through peer-to-peer platforms is quite easy. Meanwhile, using crypto or other digital assets to pay for goods or services in real-world (physical) stores, such as restaurants, retail shops, or transit, is much more cumbersome.

Many merchants don’t accept crypto, or if they do, the process is inefficient or risky for them. To bridge this gap, platforms like Digitap’s no-fee crypto exchange wallet are simplifying the user experience, enabling crypto for business transactions without high fees or technical friction.

In an effort to address these last-mile challenges, Web3 Point-of-Sale (POS) systems will enable merchants to accept cryptocurrency in person, using devices such as tablets, phones, or dedicated checkout terminals. The emerging POS system is a powerful bridge between crypto’s digital potential and physical-world commerce.

This article will explore the evolution and future of crypto payments in retail. We will look at the limitations of early systems, the innovations of new Web3 POS platforms, and the benefits they can offer to both merchants and consumers.

The Early Days: QR Codes and High Fees

In the early generation of crypto payments, the process was quite simple; a merchant would display a QR code on a tablet or mobile device, and the buyer would scan this code using their own crypto wallet. This model was hassle-free because it required little hardware, just a screen to display the QR code, and to leverage users’ existing wallets.

Another reason was the complex nature of wallet addresses. For context, Ripple addresses are 25-35 characters, Ethereum (ETH) addresses have 42, and Bitcoin (BTC) addresses contain 26-35. This leaves quite a margin for error, especially when entered manually.

Instead, the QR code encodes the merchant’s wallet address and the amount to pay. Once scanned, the customer initiated a blockchain transaction to send the funds. But, despite this simplicity, the system introduced a series of serious problems, both at the sender’s and receiver’s end.

The Problem

Slow Confirmations: Blockchain transactions don’t always settle instantly. Many networks require several confirmations, especially in cases where new blocks are added. Before a transaction is considered final. For example, payment gateways often wait for 3-6 confirmations to ensure safe settlement.

On Bitcoin, a confirmation can take approximately 10 minutes, and during network congestion, it may even stretch to over an hour. On Ethereum, although block times are generally faster, the exact confirmation time depends heavily on the amount of gas fee paid.

High Transaction Fees: On popular networks like Ethereum, transaction fees (also known as gas) can become very expensive when the network is congested. According to the Bank for International Settlements (BIS), as demand for Ethereum grows, gas fees can rise exponentially because users bid more to have their transactions included quickly. These costs can make small-value payments (like a coffee or a snack) economically unviable for both customers and merchants.

User Confusion & Friction: For mainstream users (those unfamiliar with cryptocurrency), the QR and wallet method can feel technical; they need to understand how to scan, choose gas fees, and confirm transaction details. The uncertainty around how much gas to pay and how long the transaction will take adds anxiety.

Due to the fee volatility and confirmation delays, some users in forums have noted that paying in crypto feels too risky or slow for everyday purchases.

The 2025 Solution: Seamless Web3 Point-of-Sale

Key Innovation Making Crypto Payment Possible

• Layer-2 Networks (L2):

Layer 2 solutions in the blockchain ecosystem, such as Arbitrum, Optimism, and Base, are referred to as L2 because they process most activities off-chain, then send the results back to Layer 1. This solution has significantly reduced transaction costs and sped up confirmations.

By handling transactions off the Ethereum chain and batching or settling them later, these layer 2s make payment nearly instant and very cheap for day-to-day use. Because of this, a crypto POS system can rely on L2 networks to process payments in real-time, making crypto spending feel as smooth as traditional card payments.

• Stablecoins:

Stablecoins like USDC, USDT, and DAI are central to the new Web3 POS model because they eliminate the volatility risk for merchants. With many payment processors offering instant conversion of received crypto into stablecoins (or even fiat), businesses can lock in value right away instead of worrying about price swings.

Stablecoins are now viewed as a foundational layer of programmable money, offering a global, low-latency, low-volatility infrastructure for payments.

NFC and Tap-to-Pay Crypto Payments System:

New hardware and software are making it possible to pay with crypto using Near Field Communication (NFC), the same technology behind Apple Pay or Google Pay. For example, ivendPay has launched a system where users can tap their NFC-equipped phone to pay from a crypto wallet. Companies like SPARK+ offer a crypto NFC card that lets customers load their preferred cryptocurrency and tap to pay at POS terminals, integrating seamlessly with existing merchant systems.

Crucially, Flexa has introduced tap-to-pay support using NFC-enabled hardware wallets. Instead of needing a phone, a user taps a hardware wallet (like the Burner card), enters a PIN on the POS device, and the transaction is signed and processed on-chain.

Under the hood, this leverages host card emulation (HCE), software that mimics physical cards via mobile apps, allowing contactless payments without needing a dedicated secure chip.

For consumers, this means you can use your Digitap crypto debit card, which supports Apple Pay and Google Pay for smooth tap-to-pay transactions at millions of locations while spending crypto directly from your digital wallet.

The Benefits for Merchants

• Lower transaction fees: crypto payment rails often cost less than traditional card systems, which typically charge merchants up to 2-3% per transaction. With blockchain-based payment, particularly when using Layer-2 networks like Arbitrum or Base, fees can drop to just a few cents or even fractions of a cent. This can significantly improve margins, especially for high-volume or low-margin businesses.
• Instant Settlement: Credit card payments can take one to three business days to fully settle, and chargebacks can further delay the release of funds. In contrast, crypto payments settle almost instantly on most modern networks. Faster settlement improves cash flow and reduces the risk of payment reversals.
• Access to a New Customer Base: By accepting crypto, merchants can tap into a growing community of tech-savvy, globally distributed, and often higher-spending consumers. Many crypto users actively prefer businesses that accept digital assets, giving merchants a competitive edge and increasing their brand visibility within the Web3 ecosystem.
• Global and Borderless Transactions: Conventional payment systems can create hurdles for international transactions, from currency exchange costs to slow bank processing times and expensive cross-border fees. Crypto payments remove these obstacles by enabling funds to move globally with the same speed and low cost as a local transfer. This allows merchants to reach customers worldwide more efficiently and simplifies operations when collaborating with international partners.
• Enhanced Security and Reduced Fraud: Card payments leave merchants vulnerable to various types of fraud, such as chargebacks, compromised card details, and identity misuse. In contrast, crypto payments use cryptographic authentication and don’t require customers to disclose personal financial data.

Since blockchain transactions can’t be reversed, chargeback fraud is essentially removed from the equation. The result is stronger payment security, fewer fraud-related losses, and a reduced reliance on costly fraud prevention systems.

The Benefits for Consumers

• Self-Custody and Control: With Web3 payments, consumers can pay directly from their own self-custodial wallets, meaning they maintain control over their funds. This reduces reliance on banks or centralised intermediaries. Research is exploring protocols that combine self-custody with privacy, using cryptographic techniques so users don’t sacrifice anonymity.
• Privacy: Blockchain can improve payment privacy by minimising how much personal data is shared. Some self-custody payment systems use zero-knowledge proofs to verify transactions without revealing detailed personal or transaction data. In loyalty programs, blockchain enables users to participate without revealing their full identity or purchase history, giving more control over data sharing.

There also exist privacy-preserving incentive protocols, such as the Boomerang protocol, that let users earn rewards without compromising their privacy.

• Rewards and Loyalty: Crypto and Web3 POS systems can integrate with on-chain loyalty programs built on blockchain and smart contracts. This enables customers to earn tokenized or crypto rewards, such as fungible tokens or Non-fungible Tokens (NFTs), for making purchases. Because the rewards are on-chain tokens, they can be traded, transferred, or even used across different brands or platforms rather than being locked into a single store’s program.

Smart contracts enable transparent, automatic reward distribution. As soon as a user makes a qualifying purchase, their wallet can receive tokens without manual intervention. The decentralised nature of these programs also fosters community and engagement, which means users can influence loyalty program dynamics, and brands can run gamified reward systems (leaderboards, missions, etc.).

• Easy Cross-Border Payments: With crypto, users can make purchases across borders without worrying about converting the fees or delays caused by traditional banks. Travellers, freelancers, or anyone purchasing from global e-commerce stores can easily make use of crypto point-of-sale services.
• Secure Payment systems: users no longer need to expose their personal data when making transactions. Web3 payments make use of cryptographic structures that protect users’ data from third parties, preventing identity theft, exposure to cyber thieves, and reducing centralised data breaches that often affect millions of customers at once.
