Key takeaways :
- Mobile payments let people pay with phones, wearables, or apps instead of cash or cards
- They work through technologies like NFC, QR codes, Tokenization, and biometric authentication
- They matter because they make payments faster, safer, and more convenient for customers and businesses
A typical day for the modern shopper looks something like this. Coffee paid for with a tap of a phone. Lunch ordered through an app and collected from a counter. A train ticket scanned from a screen. A hotel checked into without ever stopping at reception.
None of these involves cash or a physical card. All of them are mobile payments.
The shift has been quick. Around 86% of global consumers now use contactless payment methods, with a large share of those transactions running through a phone. For merchants in retail, hospitality, and travel, accepting mobile payments has moved from a competitive advantage to a baseline expectation.
This page sets out what mobile payments are, how the technology works, the main forms they take, and why they matter for any business with customers who carry smartphones.
What are mobile payments?
A mobile payment is any transaction initiated, authorised, or completed through a mobile device, whether a smartphone, tablet, or wearable like a smartwatch. In most cases the payment instrument is a card stored in a digital wallet. It can also be a bank account linked through an app, or a topped-up balance in a loyalty platform like Starbucks Rewards. The global mobile payments market reached around $5.12 trillion in 2025 and is forecast to keep growing at a double-digit annual rate.
The category covers a wide range of behaviours. A tourist tapping their phone at a card terminal in a duty-free shop. A guest authorising a room charge inside a hotel app. A diner splitting a bill via QR code at a restaurant table. What unites them is the device.
How mobile payments work
Several layers run between the customer's tap and the merchant getting paid.
- The wallet. A digital wallet (Apple Pay, Google Pay, Samsung Pay, Alipay, WeChat Pay, and many regional equivalents) stores a tokenised version of a payment card or bank account on the device. The customer does not store their actual card number on the phone. They store a token that maps back to the card on the network's secure servers.
- The communication method. Phones reach the merchant's till or checkout through one of three channels. NFC (near-field communication) handles tap-to-pay in person. QR codes carry pay-at-table and pay-by-display flows. App-to-server APIs run everything in-app and online.
- Authentication. The device confirms the customer is who they say they are. Face ID or fingerprint usually does the unlock, with a passcode as fallback. Larger or cross-border purchases sometimes layer on a 3-D Secure check.
- The acquirer and gateway. Once authentication clears, the transaction flows through a payment gateway to the acquirer (the merchant's bank), the card scheme (Visa, Mastercard, American Express), and the issuing bank. Approval comes back in milliseconds.
Settlement. Funds move from the customer's bank to the merchant's, typically same-day or next working day with modern acquirers.
From the customer's perspective, the whole cycle takes under a second.
Types of mobile payments
Several distinct mobile payment forms now coexist. Most merchants support more than one.
- Contactless payments via mobile devices. The customer holds their phone or wearable near an NFC-enabled terminal. The terminal reads the tokenised card, and the transaction processes like a contactless card payment. This is the dominant in-person mobile method in most Western markets.
- Wallet-based payments. A customer pays online or in-app using a stored wallet credential. Apple Pay and Google Pay are the obvious examples in the West. Alipay and WeChat Pay dominate parts of Asia. The wallet handles authentication and credential storage; the merchant receives a processed payment without handling a card number.
- In-app payments. Payment is completed inside a merchant's own app. A coffee chain's app, a hotel group's app, an airline's app. Customers select what they want, confirm payment, and get a digital receipt. The merchant keeps the relationship with the customer end-to-end and gains useful data about purchase patterns.
- QR code payments. Either the merchant displays a code and the customer scans it, or the customer's wallet generates one and the merchant scans it back. Confirmation happens in the wallet or banking app. QR is the default mobile payment method across China, India, and much of Latin America. In China alone, QR codes account for over 90% of mobile payment transactions. Western markets are catching up, especially in restaurants for pay-at-table.
- Account-to-account and open banking payments. A growing category. The customer authorises a direct payment from their bank account to the merchant, often through a banking app, without a card in the middle. Lower fees for merchants. Strong fraud profile because the bank handles authentication.
Mobile payment security and authentication
Mobile payments are typically more secure than physical card payments, for a few reasons.
- Tokenisation. The phone never holds the actual card number. The wallet holds a token, useless to a thief. Even if the device is compromised, the underlying card details are not exposed. Tokenisation can drop fraud rates by around 26% in retail environments, and Visa has reported that tokenised transactions can reduce fraud by up to 60% versus transactions using actual card data.
- Device-level authentication. Biometric checks and device passcodes mean the phone itself becomes part of the authentication. A stolen phone alone cannot complete a payment.
Strong Customer Authentication (SCA) and 3-D Secure. In Europe, regulation under PSD2 requires two-factor authentication on most online card payments. For mobile transactions, the 3DS 2.x flow often looks invisible to the customer, because biometrics on the device satisfy the second factor.
Merchants who get SCA right see fewer declines and lower fraud at the same time.
The operational benefit goes beyond fraud prevention. Tokenization can also reduce PCI compliance scope by up to 80%, shrinking audit cost and complexity.
Benefits of mobile payments for merchants
The case for accepting mobile payments is well-established.
- Higher conversion at checkout. A customer who can pay with one tap or one biometric prompt is less likely to abandon a purchase than one asked to type a 16-digit card number into a small keyboard. Offering multiple payment options, including mobile wallets, can boost conversion rates by up to 30%.
- Faster transactions in person. Tap-to-pay clears in roughly a second. QR-based pay-at-table turns restaurant tables faster, with the customer not waiting for a bill, a server, or a terminal handover.
- Lower exposure to card data risk. Less card data passing through merchant systems means less attack surface. Tokenisation, P2PE, and PCI Level 1 hosting (Planet's standard) keep cardholder data out of the merchant's environment entirely.
- Operational data. Mobile payments produce richer transaction data than cash. Customer identity, location, and time stamps flow into the transaction record and feed loyalty, marketing, and inventory systems through PMS, POS, and ERP integrations.
Better access to international customers. A traveler from China is more likely to use Alipay or WeChat Pay than a Visa card.
Accepting those wallets removes friction for inbound tourism, business travel, and luxury retail. Currency conversion at the moment of payment lifts opt-in rates and creates a small additional revenue stream.
Benefits of mobile payments for customers
The customer side of the equation is what drives merchant adoption.
- Speed. A tap is faster than a swipe, which is faster than chip-and-PIN, which is faster than counting cash.
- Convenience. Most people pay with the phone they were already holding. The wallet stays in the bag.
- Security. A lost phone with biometric locks is lower-risk than a lost wallet full of cards, ID, and cash.
- Choice. Wallets let customers switch between cards, currencies, and accounts inside one interface.
- Receipts and records. Digital receipts, automatic categorisation, and integration with budgeting and expense apps come as standard.
In hospitality specifically, research found that 73% of hotel guests say they are more likely to return to and spend more at hotels that allow them to pay, manage invoices, and check out via mobile or contactless options, so mobile payments fit a wider expectation around how the whole stay is delivered.
Challenges and considerations for merchants
Mobile payments are mature, but adoption still has friction points.
- Hardware compatibility. Older POS terminals do not support NFC or modern QR flows. Most newer terminals handle both, so a refresh cycle resolves this.
- Software integration. A mobile wallet payment that does not write back to a hotel PMS, a restaurant ordering system, or a retail ERP creates reconciliation headaches. Integration matters as much as acceptance, which is why merchants often choose payment partners with established connectors to their existing PMS or POS.
- Regional preferences. A retailer in central London serving Chinese tourists needs Alipay and WeChat Pay. A US-facing merchant needs Apple Pay and Google Pay. A Brazilian business needs Pix. An Indian one needs UPI. International merchants cannot pick one or two wallets and stop.
- Connectivity and offline modes. Live mobile payments need a working connection at the terminal. Partners that offer stand-in or store-and-forward modes (the terminal handles the payment locally and syncs later) keep the till running through outages.
Customer education. A small share of customers, often older or in lower-income segments, does not use mobile payments.
Cash and cards are not going away, and a strategy that withdraws those options too aggressively risks alienating part of the customer base.
The future of mobile payments
Several trends are shaping the next phase.
- Account-to-account growth. Open banking and instant payment rails are pulling volume away from cards. For high-value or recurring payments, A2A is increasingly attractive to both sides.
- Embedded and invisible payments. Inside hotel apps, ride-share apps, and connected-car experiences, the payment moment is becoming part of the journey itself. The customer authorises once, then transactions complete in the background.
- Biometric authentication at the terminal. Airports and retail chains are trialling face-based payment that bypasses the device. The phone is still there. The customer just does not need to take it out.
- AI-driven fraud detection. As volumes grow, fraud detection moves from rule-based systems to machine learning models that score every transaction in milliseconds, catching anomalies that rule engines miss.
- Currency and tax integration. International customers increasingly expect to see prices in their own currency and to claim VAT refunds digitally. Solutions like Pay in Your Currency and digital tax-free shopping now integrate directly into the mobile checkout flow.
Make mobile payments work for your business
Accepting mobile payments well means accepting them everywhere a customer might want to pay, in the format that the customer expects. For a UK retailer, that means Apple Pay and Google Pay at the till. For a hotel group with international guests it means Alipay and WeChat Pay at reception, currency conversion at the terminal, and digital Tax Free shopping for the eligible visitor. For a restaurant it might mean QR-based pay-at-table that integrates with the POS.
Planet was built to handle this on a single platform: card acquiring across the EEA, UK, and Switzerland, acceptance for the major card schemes and digital wallets, P2PE-validated terminals, a PCI Level 1 hosted gateway with 99.9% uptime, Pay in Your Currency in 48+ countries and 150+ currencies, Tax Free Shopping built in, and PMS and POS integrations that turn each mobile transaction into reconciled data.

Mobile payments FAQ
What is the difference between a mobile payment and a contactless card payment?
A contactless card payment uses a physical card. A mobile payment uses a phone or wearable. Both can run on the same NFC technology at the terminal. Mobile payments add an extra layer of authentication through the phone's biometrics.
Are mobile payments safer than card payments?
For most use cases, yes. Tokenisation, device biometrics, and on-device authentication make mobile payments harder to compromise than a swiped or chipped card. The card number never travels through the merchant's systems.
Do I need new terminals to accept mobile payments?
For in-person wallet payments, the terminal needs NFC support. Most terminals sold in the last several years do. For QR code or in-app payments, no terminal is needed.
How do mobile payments comply with PSD2 and SCA?
Mostly automatically. The phone's biometric check is the "something the customer is" factor; the device itself is "something the customer has." Together they satisfy SCA's two-factor requirement, which means fewer manual 3-D Secure challenges interrupting European online checkouts.
Which mobile payment methods do international customers prefer?
It depends on where they are from. Apple Pay and Google Pay carry most North American and Western European customers. Alipay and WeChat Pay are near-universal for Chinese-issued cards. UPI handles India, Pix handles Brazil. Merchants should accept what their actual inbound traffic uses, which the analytics will tell them.
Can mobile payments work offline?
Some can. Pre-authorised in-app payments and certain transit applications work offline. Live wallet transactions at a terminal usually need connectivity, though some terminals support stand-in or store-and-forward modes for short outages.
How much do mobile payments cost merchants?
Card-backed wallet payments cost roughly the same as the underlying card would. Account-to-account through open banking comes in cheaper. The merchant's blended cost depends on customer mix, acquirer contract, and whether value-added services like currency conversion are offsetting processing fees.
