What is a POS transaction?

Apoint-of-sale transaction, meaning POS transaction, is the moment a customer exchanges money for goods or services at your location. This event can take place in your brick-and-mortar store, in your restaurant, at a pop-up truck, or anywhere else you have might have physical POS hardware on hand. 

POS transactions consist of the calculation of the amount owed, the transfer of funds, and the generation of a receipt. The exchange is the central moment where inventory levels adjust and revenue enters your books.

POS transactions go beyond the point of sale

Experienced operators know a transaction is more than a simple exchange of cash. The sale is a data point that feeds into your wider ecosystem, from loyalty programs to supply chain management.

For example, picture every moment a retail shopper taps their card on your mobile POS device in your store. Your company is gaining insightful information on the backend regarding which items are running low in specific sizes and may need to be replenished, which brands, styles, colors, and aesthetics are the most popular for this location of your store, and even which SKUs might have issues if they’re leading to a high rate of returns. 

Of course, the information spans much more than inventory; with a synced POS system, your transactions will send key data to your bookkeeping and accounting software, software for tax and compliance, customer relationship management (CRM) software and more.

It can even impact your marketing and sales activities. Here’s an example based on the same shopping trip in your retail shop:

• The POS transaction syncs with your CRM in real time
• Your automated marketing system can send a thank-you email to your customer shortly after the transaction takes place
• The next sales email they receive may be customized to offer complementary SKUs, while the SKUs they purchased can be removed from those assortments

As a result, the customer enjoys access to a concierge-like experience and might feel a stronger affinity for your store due to your ability to anticipate their preferences and needs. It’s clear that POS transactions hold much more value than simply making the sale.

Note: Point of sale and point of purchase are not synonymous; point of purchase is the place and time where a consumer decides whether or not they’d like to make a purchase.

How do POS transaction work?

Behind the scenes, POS transactions are really sophisticated workflows that connect these customer purchases, payment authorizations, transaction completions, settlements, and backend updates. That’s one reason why it’s essential to choose the right system for your small business.

This is how it works: 

• The POS transaction process begins when your team member scans SKUs or enters orders into the POS, such as for a retail store purchase or restaurant meal, respectively. 
• Your POS tallies the total, including sales tax, if applicable. 
• Next, the customer presents a card or digital wallet to your terminal to be scanned, tapped, inserted (or in the case of non-integrated payments, keyed in). 
• Your system encrypts their card data to protect their financial information and identity, and sends the encrypted information through a secure gateway to the processor for authorization.
• Once the issuing bank approves the request, the processor settles the funds into yourmerchant account. 
• You can use your POS to print a receipt if the customer desires a physical copy or even email them a receipt (a popular option for retail transactions). 

The sequence happens in seconds but relies on complex communication between the card brand, the bank, and yourPOS system. It’s paramount to have a secure, reliable and fast POS system, regardless of what industry you’re in. 

Types of POS transactions

Knowing every POS transaction type is how you manage margins and risk. A modern checkout is more than just cash or credit—you need to accept a mix of payment methods to capture every sale.

So, what is a POS transaction type? POS transaction types include paying with any one of various payment methods (such as card payments or cryptocurrency), the channel of the transaction (such as tableside, mobile transactions or transactions at a store register). All the different types of POS transactions can also be classified based on their use cases, such as to-go/pickup orders in restaurants and bar tabs.

Each classification carries specific rules for fees, settlement times, and fraud liability. A keyed-in card costs more than a chip dip. Knowing the difference helps you optimize your hardware setup and train staff on the most cost-effective ways to process payments. We categorize transactions by the tech used to transfer value. Merchants need this information for strategy, cash flow management, risk management, and compliance.

Card payments

Card payments are the standard for non-cash sales in retail and hospitality. This is because card payments represent a long-established way to pay. For decades, they were the primary alternative to cash. However, that doesn’t mean it’s not evolving. Today, the group includes:

• magnetic stripe swipes
• EMV chip “dips” 
• contactless taps

Card payments may be made at POS stations, such as cash registers, but also with mobile, handheld POS devices. The flow is a communication chain between the terminal, processor, and issuing bank.

Physical card presence dictates the fee structure. “Card-present” happens when the customer interacts with the terminal. “Card-not-present” (CNP) is when staff manually key in numbers. You see CNP with phone orders or when a magnetic strip fails to read. CNP costs more because the fraud risk is higher.

Cost is also an important factor to consider outside of CNP transactions. It’s important for small businesses to research payment processing fees and how well various POS systems can integrate with their existing tech stack.

Speed matters here—contactless taps are faster than chip insertions. Encouraging customers to tap rather than dip shaves seconds off average transaction times during peak hours. When you’re experiencing long lines or a shortage in staff, every second saved makes a difference.

Mobile and digital wallet payments

Digital wallets are what customers use to pay with phones or wearables instead of physical cards. The POS transaction type uses near field communication (NFC) to send data to the terminal. Apple Pay, Google Pay, and Samsung Pay are common examples of mobile and digital wallets.

Security is the main benefit. Wallets use tokenization to replace the card number with a one-time code. The system never stores the actual financial data. You reduce exposure to data breaches and PCI compliance issues. Scanning or tapping is also faster than fumbling for a bag or wallet (a benefit appreciated by customers and teams alike) You need NFC-enabled terminals to accept the payments.

Since consumers are becoming more comfortable with biometric authentication, adoption is growing 

Consumers have also started discovering the benefits of using digital wallets and have grown more comfortable with what was once primarily the preference of tech-savvy and security-savvy first movers. To encourage better relationships with customers and repeat sales, it’s important to offer consumers’ favorite ways to pay. What’s more, integrating mobile wallets prepares the business for a future where physical cards may become obsolete.

QR code payments

QR code payments are a flexible alternative to hardware-dependent methods. A customer scans a code at the register or presents a screen for staff to scan. The system links the code to a funded account or digital wallet to complete the transfer.

Entry barriers are low since you need minimal extra hardware. The option works well for businesses looking to offer touch-free payments without upgrading an entire terminal fleet. You just need robust internet connectivity for the real-time verification.

QR code payments can increase the speed of checkout and reduce friction, such as when featured on bills at casual restaurants.

Gift card and store credit

Gift cards and store credit are closed-loop payments where you hold the funds due to pre-loaded value. Customers redeem pre-loaded value stored in the database at checkout instead of transferring new money. The transaction is the settlement of a liability rather than new revenue.

It’s important to track balances meticulously to prevent revenue leakage. The POS system needs to update the outstanding balance immediately. Proper management stops you from overstating cash flow when a card is purchased versus when the card is used. 

When managed with care, gift cards can be an excellent way to improve cash flow; while returns exchanged for store credit can encourage repeat business and additional purchases when the policy communicated clearly and with care.

Loyalty points and rewards

Loyalty programs turn earned points into currency at the point of sale. When your loyalty/redemption program is integrated with your POS, your team members can instantly access customers’ point balances to inform them of reward opportunities and options at the time of the sale. 

Customers can then use those rewards to offset the cost of the purchase at hand or to access other member privileges, such as gifts with purchase (GWP). The transaction requires tight integration between customer relationship tools and the payment processor.

The system then goes on to update any usage of points in real time to ensure point balances are always accurate and consistent. The system must also deduct points in real time to prevent double usage. Treating points as a distinct payment type helps measure the cost of retention efforts. You also get accurate tax reporting on discounted sales.

Cryptocurrency

Cryptocurrency payments let customers pay with digital assets like Bitcoin or Ethereum. Most retail setups use a third-party processor to convert crypto to fiat currency instantly; this immediate conversion is essential because it protects the business from market volatility (a common occurrence in the world of crypto).

While accepting crypto attracts tech-forward consumers, however, you must consider potential transaction fees or conversion costs. The integration usually works through specialized apps on existing POS hardware. 

It’s still relatively “early days” for cryptocurrency. Because many retailers are still unclear about all of the liability and compliance considerations, it has slowed adoption and made cryptocurrency adoption quite challenging. 

FAQ about POS transactions

What is aPOS transaction fee?

A POS transaction fee is the price you pay to process a payment—usually a split between the card issuer’s interchange rate and the processor’s markup. The final cost depends on the card type, your monthly volume, and if the card is present or keyed in manually. It’s also affected by the region due to factors such as local regulations.

What’s the difference between POS and online transactions?

POS transactions happen in person with a physical card at checkout, while online transactions (ecommerce) go through a digital gateway as “card-not-present” sales. Since fraud is harder to spot without the physical card, ecommerce payments usually come with higher payment processing fees and stricter security rules than in-store dips. 

However, there are excellent embedded payment processing solutions on the market. For example, Lightspeed Payments makes it fast, easy, and convenient for customers to pay while helping you avoid abandoned carts, simplifying your workflows and operations, allowing you to sell on social, in marketplaces, and on your website—and giving you access to comprehensive sales data so you can make even savvier, strategic decisions over time.

Is an ATM withdrawal a POS transaction?

No—an ATM withdrawal is just taking cash from a bank account, not buying goods or services at a counter, so it’s not consider to be a POS transaction. Even though both use card networks, a POS transaction is strictly an exchange of money for inventory or services in retail or hospitality settings.

What is POS debit vs credit?

Debit transactions pull funds straight from a customer’s bank account and usually cost you less in fees. Credit payments borrow against a bank line of credit, so the interchange rates are higher to cover the bank’s rewards programs and fraud protection. Credit payments also offer more robust consumer protections, such as the ability to request chargebacks for problematic purchases.

How do I check my POS transaction history?

You can view transaction history right in your POS dashboard or processor portal to reconcile daily sales and settlements. Customers see the charges on bank statements—often with a “POS” label next to your business name—to tell the purchase apart from ATM withdrawals.

Are POS transactions secure?

Modern systems use end-to-end encryption and tokenization so sensitive card data never sits on your network in a readable format. For example, EMV chips create unique, one-time codes called cryptograms—and, unlike magnetic stripe cards, they’re extremely difficult to duplicate. Staying compliant with PCI DSS standards lowers the risk of data breaches and protects your business from financial fraud liability.

What is the limit of POS transactions?

Limits usually depend on the customer’s daily spending cap or a floor limit you set to trigger verification for high-value sales. And while your POS system can technically process any authorized amount, processors might flag unusually large purchases for review to prevent chargebacks. Consumer transactions can also be limited by credit card limits and daily debit card usage limits placed by their card issuers. Debit card issuers’ daily transaction limits often mirror limits set by regional entities, such as by the federal government.
