2025 Card Terminal Payment Trends: Complete Comparison of Unmanned and Non-Face-to-Face Payment Market Expansion

The hand reaching for cash at checkout has diminished. Handing over a card has become rare. A single finger touch on a phone or a QR code scan completes payment. Or payment may occur automatically the moment you enter a store without staff, pick up a product, and leave. This change is not merely a matter of convenience. The fact that domestic card approval amounts reached 1,266 trillion won in 2025, and PG service daily average usage increased 9.2% year-over-year to 15.542 billion won, shows that the payment market itself is structurally transforming. It is essential to understand how important the choice of unmanned and non-face-to-face payment terminals and online/offline payment solutions has become in business operations.

The free payment environment diagnosis conducted by TheKL Link also directly reflects this change. In consultations led by CEO Sim Jae-woo, requests have evolved beyond simple "please lower our fees" to more frequently asking "what payment terminal is right for our store structure?" This is because selecting which solution to use amid changing payment trends significantly affects business operational efficiency. This article conducts a core analysis of 2025 domestic payment market changes — the expansion of unmanned and non-face-to-face payments and comparison of online and offline terminals.

Unmanned Payment Terminals vs Traditional Wired Terminals: Where and Which to Choose?

Unmanned payment refers to a method where customers complete payments independently without staff intervention. Today's convenience store self-checkout counters, cafe tablet payment devices, and parking lot automated settlement machines are all unmanned payment terminals. In contrast, traditional wired tabletop terminals are fixed at store counters where staff swipe cards or customers directly touch the screen. With over 297.8 billion card approval transactions in 2025 and a 3.1% growth rate, this indicates that payment methods are diversifying as much as total transaction volume is increasing.

The greatest strength of unmanned payment terminals is labor cost reduction and operational efficiency. Convenience stores and cafes that have introduced self-checkout can reduce staff allocation during peak hours, and customers can complete payments quickly without waiting. TheKL Link's wireless mobile terminals (for delivery, direct sales, and event venues) operate on the same principle. However, unmanned terminals have high initial installation costs and can be complicated to address when technology fails. Wired tabletop terminals offer high stability and simple management, but require staff presence and can create bottlenecks during peak times.

Decision Criteria

Online PG vs Offline VAN: Transition in Non-Face-to-Face and Online Revenue Structure

The 9.2% increase in PG service daily average usage to 15.542 billion won in 2025 does not simply mean increased online shopping. It signifies a strengthened trend where offline stores adopt online payment functions and online-based businesses add offline payment channels. TheKL Link's online PG solutions (recurring payments, link payments, non-face-to-face collection) and offline VAN systems have overlapping areas but are fundamentally different payment structures.

Online PG is a method where customers pay via credit cards, bank transfers, or digital wallets on websites or apps. Customers can conveniently pay from home, and recurring payment settings can automate repeat purchases. This is why increasing instances of automatic payments for academy fees, rental charges, and subscription fees are processed through PG solutions. Offline VAN is a method processed in-person through store card payment terminals. Staff swipes the card or customers directly touch the screen to complete payment. Security is relatively stronger and refund processing is more intuitive.

Comparison Points

Smart POS vs Simple Payment Terminals: Food Service and Retail Efficiency War

What is expanding fastest in food service and retail is the smart POS system that handles ordering, payment, and accounting on a single machine. TheKL Link's Smart POS receives orders via table tablets at restaurants, immediately displays the payment screen, and the data is real-time linked to restaurant accounting. In contrast, simple payment terminals are optimized for quickly processing card, QR, and mobile payments. Franchises or small cafes may suffice with the latter, but restaurants or marts with over 200 daily transactions require the former.

Smart POS's strength is integrated management. Store inventory, daily sales, and staff hourly settlements are all linked so managers can make business decisions quickly. However, initial installation costs are high and there is a system learning curve. Simple payment terminals are easy to install with low costs but require manual sales data recording. TheKL Link provides customized solutions by industry considering this difference, determining which is more efficient based on monthly sales scale.

Selection Judgment Criteria

Settlement Cycle Choice and Cash Flow: Actual Differences Between Same-Day Settlement and D+3 Settlement

One of the most overlooked aspects of the 2025 payment market is settlement cycle. Even if fees are low, three-day settlement disrupts cash flow. Conversely, if fees are slightly higher but same-day settlement is received, small business owners can immediately reinvest. In TheKL Link's free diagnosis, this is the most frequently mentioned improvement point. CEO Sim Jae-woo emphasizes that "improving just the settlement cycle can enhance monthly liquidity by over 10%."

Same-day settlement's advantages are clear. A cafe can use today's 1 million won earnings as tomorrow's operating costs. It can be immediately utilized when urgent material payment is needed. However, same-day settlement can have 0.1~0.3% higher payment fees than D+1 and D+3 settlements. Additionally, if payment cancellations or refunds occur, amounts are immediately deducted from settlement funds, making calculations complex. D+3 settlement makes settlement amounts easier to predict and can absorb minor cancellations and refunds.

Financial Simulation

Payment Fixed Costs (Terminal Rental and Monthly Management Fees) vs Variable Costs (Fees) Structure Optimization

Many business owners compare only card fee rates, but actual payment costs are fees + terminal rental + monthly management fees + communication fees combined. TheKL Link's actual payment cost calculation method is (Total Monthly Payment Costs ÷ Monthly Card Sales) × 100. Using this method often reveals that places displaying low fee rates are actually more expensive. For example, even places stating 1.8% fee rates with 50,000 won monthly management fees and 30,000 won terminal rental become 2.4% actual cost ratio with 20 million won monthly sales.

TheKL Link's offline PG service explicitly separates this structure. Standard offerings include free equipment support, no monthly management fees, and free maintenance support, with only variable payment fees clearly presented. This allows business owners to know exact burdens and makes comparison easier during contract renewal. Traditional VAN services, in contrast, present complex combinations of fees plus fixed costs making comparison difficult.

Fixed Costs vs Variable Costs Selection Criteria

Communication Method Differences (Wired, Wireless, LTE) by Connection Type

Payment terminals connect to the internet in three ways. Wired connections fixed to stores (cafeterias, medical clinics) offer the highest stability but require construction. Wireless WiFi utilizes existing networks with no additional costs but experiences payment delays if WiFi signals are weak. LTE terminals excel in mobility (delivery personnel can carry them) and work anywhere but incur monthly communication fees. TheKL Link distinguishes and provides all three based on business location type.

Wired is standard for offline retail and food service. Fixed counters exist with payments occurring daily in the same location. Wireless is most popular in cafes and small stores. Tablet POS can be carried and payment completed at tables. LTE is essential for businesses with changing locations like delivery, direct sales, event venues, and golf courses. However, monthly communication fees are included in fixed costs, so low daily transaction volumes may reduce profitability. TheKL Link's free diagnosis analyzes business transaction patterns to recommend the most efficient communication method.

Payment Environment Inspection and Improvement Implementation Steps

Accurately understanding and improving current payment situations requires step-by-step approaches. TheKL Link's free diagnosis process systematizes this.

Step 1: Collect Recent 3 Months Settlement Statements and Confirm Fee Rates
Extract card sales, approval count, and fee amounts from settlement statements to calculate actual fee rates.

Step 2: Review Contracts — Identify Fixed Cost Items
Organize terminal rental fees, monthly management fees, communication fees, and maintenance contracts by explicitly stated items.

Step 3: Confirm Bank Account Deposits — Analyze Settlement Cycles and Deposit Discrepancies
Find reasons for differences between actual deposits and expected amounts in settlement statements (cancellations, refunds, etc.).

Step 4: Track Cancellations and Refunds — Calculate Loss Rates
Understanding what percentage daily cancellations represent of sales becomes criteria for choosing same-day settlement vs post-settlement.

Step 5: Re-evaluate Terminals Matching Industry and Scale
Reconsider whether currently used terminals are optimal for business structure.

Step 6: Establish Improvement Plans and Cost-Benefit Simulations
Calculate expected savings when adopting new solutions.

Step 7: Pre-Contract Change Verification
Verify settlement cycles, equipment ownership, contract periods, auto-renewal, and early termination costs.

Customized Payment Solutions by Industry: Cafes, Academies, and Hospitals Comparison

The same payment solution shows different efficiency depending on industry. TheKL Link analyzes and recommends based on industry characteristics.

Cafes — High Turnover Rate is Key

Academies — Recurring Payment and Monthly Fee Automation

Medical Clinics — Security, Personal Information Protection, and High Non-Insurance Payment Processing

Q1: Is our store's fee rate appropriate? How do I check?
A: Fee rates alone cannot determine this. Calculate (Total Monthly Payment Costs ÷ Monthly Card Sales) × 100 from recent 3-month settlement statements. Total costs include fees + terminal rental + monthly management fees + communication fees. TheKL Link's free diagnosis (010-2397-5734) automatically analyzes this.

Q2: Should I choose same-day settlement or D+3 settlement?
A: Recommend same-day settlement for businesses with irregular monthly sales or fast cash turnover (cafes, delivery pickup points). D+3 is acceptable with stable sales and low cancellation/refund rates. However, long-term perspective shows same-day settlement's cash flow benefits may be greater, so compare total 1-year costs.

Q3: Should I replace my current terminal? What to check before switching?
A: Verify whether current terminals match your transaction patterns (unmanned, in-person, non-face-to-face), experience frequent technical failures, and how much contract time remains. Early termination costs may apply, so check contracts first and compare new solution's 1-year total costs before deciding.

Q4: Will operational labor costs really decrease by introducing unmanned payment (self-checkout)?
A: Labor cost reduction naturally occurs when transaction volumes equivalent to one staff member's hours shift to unmanned payment. However, calculate initial installation costs, maintenance, and customer service costs during technical failures together. Generally, ROI emerges from cafes and convenience stores with monthly sales over 200 million won.

Q5: Do I need both online PG and offline VAN?
A: Yes, if you have both online and offline sales. Online handles non-face-to-face customers (delivery orders, recurring payments) while offline serves in-store visitors. TheKL Link provides solutions managing both channels from integrated dashboards.

Q6: How much must I increase transaction volume to lower payment fees?
A: Volume itself matters less than contract conditions and industry rating. Same cafe may have different fee rates between 50 million won and 100 million won monthly sales. TheKL Link's free diagnosis analyzes realistic fee reduction possibilities based on current transaction amounts (010-2397-5734).

| Wireless Mobile Terminal (LTE) | Superior mobility, payment anywhere, ideal for delivery and direct sales | Fixed communication costs, signal dependent | Delivery, direct sales, event venues, external sites |
| Same-Day Settlement | Immediate cash conversion, high liquidity, fast fund confirmation | Possible 0.1~0.3% higher fees, complex cancellation/refund processing | Businesses requiring daily liquidity (cafes, delivery points) |
| D+3 Settlement | Settlement amount easily predictable, can absorb minor cancellations/refunds | 3-day fund acquisition delay, possible difference between expected and actual deposits | Stable monthly sales businesses, low cancellation rate industries |

With domestic card approval amounts exceeding 1,266 trillion won in 2025, diversified payment methods have become a matter of competitiveness rather than choice. Unmanned payments will continue expanding and PG services will maintain 9.2% growth rates. The critical factor is accurately understanding which payment solution matches your business structure (transaction patterns, monthly sales, customer base).

TheKL Link's emphasis on "payment environment free diagnosis" deserves attention for this reason. Rather than simply lowering fees, it comprehensively analyzes settlement cycles, terminal types, communication methods, fixed and variable cost structures, presenting improvement directions. CEO Sim Jae-woo's consultation team inspects payment environments for over 100 businesses monthly, accumulating actual data.
