Contactless payments are growing fast across North America, and the global SoftPOS market is projected to grow at a CAGR of 16.3% through 2034 (Fortune Business Insights). Apple Pay alone is expected to reach 67 million US users by 2026. In Canada, contactless transactions account for the majority of in-person card payments, with Interac Flash debit growing rapidly across the country. Yet many merchants still rely on dedicated card readers and bulky terminals to accept a simple tap.
SoftPOS changes that. It turns an NFC-enabled Android device into a fully functional payment terminal, no extra hardware required. And when you pair SoftPOS with SUNMI’s third-generation POS devices, you get reliable tap-to-pay on commercial hardware built for all-day, high-volume use.
In this guide, we break down what SoftPOS is, how it works under the hood, and exactly which SUNMI devices support it today.
What is SoftPOS?
SoftPOS, short for Software Point of Sale, is a technology that allows an NFC-equipped device to accept contactless payments directly, without a separate card reader or payment dongle. The payment acceptance logic runs as a software application on the device itself.
Think of it this way: traditional payment acceptance requires dedicated hardware certified to read and encrypt card data. SoftPOS moves that functionality into software, letting the device’s built-in NFC antenna do the work.
For merchants, that means fewer devices on the counter. For ISVs and ISOs, it means faster deployments and lower hardware costs per location.
North America already accounts for 34% of the global SoftPOS market (Fortune Business Insights), and adoption is accelerating as more payment processors certify SoftPOS solutions.
How SoftPOS works
The SoftPOS transaction flow is straightforward, but the technology behind it is anything but simple. Here is what happens in the few seconds between a customer’s tap and a completed sale:
1. NFC Tap
The customer holds a contactless card, phone, or wearable near the device’s NFC antenna. The device detects the payment credential.
2. On-Device Encryption
The SoftPOS application encrypts the card data directly on the device using secure cryptographic processes. The payment credential never exists in plaintext outside the secure environment.
3. Authorization Request
The encrypted transaction data is sent to the payment processor for authorization. This step works the same way it does with any traditional terminal.
4. Transaction Complete
Once authorized, the device confirms the payment and generates a digital or printed receipt.
What makes modern SoftPOS implementations powerful is edge processing. Rather than relying entirely on cloud-based validation, the device handles encryption and initial processing locally. This reduces latency and allows transactions to complete even in environments with intermittent connectivity.
SUNMI devices take this further with hardware-backed security modules and SUNMI’s Device Management Platform (DMP), which lets operators push SoftPOS app updates, monitor transaction health, and manage device fleets remotely.
SoftPOS vs traditional payment terminals
| Feature | SoftPOS | Traditional Terminal |
|---|---|---|
| Additional hardware needed | No – uses built-in NFC | Yes – dedicated card reader |
| Deployment speed | Minutes (app install) | Days to weeks (shipping, setup, certification) |
| Upfront hardware cost | Lower – no separate reader | Higher – terminal + peripherals |
| Contactless support | Native | Requires compatible reader |
| Remote updates | Yes, via DMP or MDM | Limited, often manual |
| Flexibility | Runs alongside other business apps | Single-purpose device |
| Security | PCI-compliant software encryption | Hardware-based encryption |
| Chip/swipe support | No – contactless only | Yes – all card types |
The bottom line: SoftPOS is ideal for merchants and environments where contactless acceptance is the priority. It does not replace chip-and-PIN or magstripe entirely, but for the growing majority of tap-first transactions, it eliminates the need for a standalone reader.

Why SUNMI hardware is built for SoftPOS
Not every Android device can run SoftPOS reliably. Consumer phones lack the security architecture, fleet management tools, and long-term OS support that commercial payment applications require. SUNMI devices are designed specifically for this workload.
Google AER Gold Partner. SUNMI is a Google Android Enterprise Recommended Gold Partner, meaning every device meets Google’s strict standards for enterprise deployment, security patching, and managed device lifecycle.
Full GMS Certification. All third-generation SUNMI devices carry Google Mobile Services certification. This ensures compatibility with the full Android app ecosystem, including SoftPOS applications that rely on Google Play Services for secure NFC access.
DMP Remote Management. SUNMI’s Device Management Platform lets ISVs and ISOs deploy SoftPOS apps, push configuration updates, and monitor device health across thousands of terminals from a single dashboard. No truck rolls, no manual setup.
Global Payment Ecosystem. SUNMI partners with major payment processors and SoftPOS providers worldwide. This means ISVs building on SUNMI hardware can tap into an existing certification pipeline rather than starting from scratch.
SoftPOS use cases
SoftPOS is not limited to one industry. Any environment where customers expect to tap and pay is a fit.
Retail stores. Accept contactless payments at the counter or on the sales floor with a handheld V3 device. Staff can check inventory, process returns, and take payment without returning to a fixed register.
Full-service restaurants. Bring the V3 Family tableside so guests can tap their card or phone right at the table. No more walking cards to a back-of-house terminal.
Quick-service and fast casual. Deploy SoftPOS on D3 countertop devices or CPad tablets at the register. Pair with self-service kiosks like the K2 for contactless ordering and payment in a single flow.
Pop-up shops and events. A V3 Mix with SoftPOS turns any location into a payment-ready storefront. Canadian merchants using Interac Flash and Moneris-certified payment apps can accept contactless debit and credit on the same device. No external readers, no complex setup.
Delivery and field service. Drivers and technicians can accept tap payments on the spot using a handheld SUNMI device. The transaction is encrypted and processed in real time.
Hotels and hospitality. Check guests in, process incidentals, and accept payment with a single tablet device at the front desk or roaming with a V3 in the lobby.
SUNMI and Wink: biometric payment integration
Beyond card-based SoftPOS, SUNMI has partnered with Wink to bring biometric payment acceptance to its device ecosystem. This integration supports face and palm recognition for payment authentication, enabling customers to pay without a card or phone at all.
While biometric payment is still in its early stages in North America, the fact that SUNMI hardware already supports the Wink integration means merchants and ISVs investing in SUNMI devices today are positioned for the next wave of payment innovation.
