What Is a POS Terminal Solution and How Does It Work?


Handling transactions can often feel like a juggling act for businesses, with the need for speed and accuracy in a fast-paced world. This is where POS solutions step in, offering a lifeline through state-of-the-art POS terminals. This guide will discuss the intricacies of these systems that revolutionize payments, examine various POS types, and the extra services they bring. Plus, we’ll spotlight the advantages of digital POS solutions and share insights on picking the best fit for your enterprise’s unique pulse.

What Is POS and How Does It Function?

A POS system is an integrated blend of physical devices and specialized software crafted to facilitate and manage various payment types. The tangible component, the hardware, consists primarily of a machine that processes card payments. Additionally, the software component seamlessly administers additional payment options, oversees the transaction process, and offers supplementary services that enhance customer transactions.

Modern POS systems are diverse, accommodating every payment method imaginable:

  • Cash and Check Processing: Ready to handle traditional currency and written cheques.
  • Magnetic Strip Cards: Equipped for swift debit, credit, and prepaid card swiping.
  • Chip-Embedded Cards: Capable of processing the extra security of chip-enabled cards.
  • Contactless Transactions: Advanced to support tap payments from mobile wallets, UPI, and QR codes for the ultimate convenience.

Understanding POS Terminal Payment Methods:

A POS terminal offers three convenient methods for card payments:

  • Swipe: A quick swipe through the POS terminal kicks off the purchase of cards with a magnetic stripe.
  • Insert: Chip cards are inserted into the POS slot, staying put while the transaction is securely processed.
  • Tap: Cards equipped with EMV chips can make contactless payments; just a tap against the POS terminal leverages NFC technology to complete the transaction.

The transaction data is securely sent through encryption over radio waves, ensuring a quick and safe connection. This modern method removes the necessity of physically swiping or inserting your card or even passing it to the cashier.

When you kick off a payment at a POS terminal, here’s the behind-the-scenes action:

  • The terminal contacts the merchant’s acquirer bank, the financial institution behind their card services.
  • It requests the customer’s verification to green-light the process.
  • Payment networks like Visa or Mastercard step in to ping the customer’s card-issuing bank for the thumbs up.
  • The issuing bank quickly verifies the transaction’s legitimacy and approves.
  • The POS terminal gets the message that everything’s A-OK, signaling a successful exchange.
  • And just like that, a receipt pops out, marking the end of the transaction journey.

Types of POS

POS terminals are the heart of business transactions, coming in various forms to suit any business need. Here’s a closer look at the different types of POS solutions:


These POS terminals might be bulkier, but they get the job done, providing a no-frills solution for card payments. Despite their size, they feature small screens and the essential tools for card-based transactions.

2) Mobile POS (mPOS):

This sleek innovation partners with your smartphone and a dedicated payment app. With a suite of connectivity options like GPRS, 3G, WiFi, and Bluetooth, along with USB for physical connections and NFC for contactless interactions, mPOS systems are the versatile choice for businesses on the move.

3) Android POS:

Android POS systems are the multitaskers in the POS family, eliminating the need for separate devices to manage sales and deliveries. These all-in-one devices come equipped with a barcode scanner, receipt printer, and the ability to process a swipe, chip-insert, or contactless card while running various apps. They integrate deeply into business systems and offer robust internet connectivity through 4G, 3G, and WiFi.

4) Electronic POS (ePOS):

Transform your smartphone into a full-fledged POS terminal with an ePOS solution. Merchants can process many payment types through a simple app, including UPI, mobile wallets, and SMS payments. This virtual POS system not only facilitates transactions but also assists in recording and reconciling them within the app, streamlining the entire sales process.
