Payments On The Go

Mobile acceptance for field services, trades and pop-ups

Across the globe millions of individuals and businesses are making and taking sales out in the field. They do so in the most diverse of places. 

In the UK alone, more than 6.7 million people work in remote roles across over 1.2 million organisations. These roles cover everything from plumbing and electrical services to engineering, facilities management and environmental services. Roughly one in five UK businesses now rely on field teams.

Whether receiving goods and services in homes, offices, construction sites, at events or roadside, today’s customers expect to be able to pay by alternatives other than invoices or cash.

Not just mobile trades

The ability to set up shop anywhere, and start selling immediately, is also transforming how retailers think about their physical presence.

Pop-up retail has become a core strategy for brands testing new markets and launching products. In Britain, the pop-up sector is valued at over £2.3 billion and continues to grow rapidly worldwide.

From food stalls to seasonal kiosks and experiential brand activations, sales depend on payment systems that can be deployed and scaled instantly. These systems must operate without fixed infrastructure and accept debit and credit cards, mobile wallets, buy now pay later, peer-to-peer and real-time payments.

If you work where your customers are, your payments should too

Thanks to today’s mobile POS and SoftPOS solutions it’s now possible to empower all types of in-field workers with practical, frictionless and compliant payment acceptance.

Being able to take payment immediately:

  • reduces payment delay and improves cash flow
  • eliminates invoice chasing
  • reduces bad debt risk
  • creates a more professional impression
  • is more secure and transparent than cash

Android POS solutions lead the way

While there are various acceptance options like add on card readers and QR code payments, modern Android-based mobile POS solutions are rapidly gaining traction in mobile use cases. They are popular with tradespeople and enterprise field teams alike. These portable devices strike the ideal balance between performance and cost-effectiveness.

Solutions from companies like Castles Technology demonstrate why Android POS has become the backbone of mobile commerce.  Here are 8 ways they deliver what mobile workers want:

  1. Android operating system
    Android provides a secure, flexible platform that supports invoicing apps, scheduling tools, CRM systems and reporting software, all on one device. Instead of carrying multiple tools, field workers can manage operations and payments from a single terminal.
  2. 4G LTE, 3G and GPRS connectivity
    Built-in cellular connectivity allows payments to be processed anywhere, from remote job sites to outdoor events, with no fixed broadband required and no delays.
  3. Long battery life
    High-capacity batteries support full-day use, ideal for engineers and tradespeople constantly on the move.
  4. Rugged design
    Field environments are tough. Durable Android POS devices are built to withstand drops, dust and demanding conditions.
  5. All-in-one payment acceptance
    EMV chip, contactless, magstripe and mobile wallets are all supported, ensuring customers can pay their way.
  6. Built-in printer (select models)
    Instant printed receipts provide proof of service and payment, enhancing professionalism and reducing disputes.
  7. Secure and PCI-compliant
    Advanced encryption and tokenisation protect customer data and reduce fraud risk.
  8. Compact and lightweight
    Ergonomic designs are easy to use, won’t weigh your sales teams down and fit easily into their carry kits.

For large organisations managing distributed teams, Android POS devices also offer centralised management, remote updates and app deployment. These features are critical for operational efficiency.

SoftPOS empowers small businesses

While dedicated Android MPOS terminals are ideal for many field teams, SoftPOS has opened the door even wider. This is particularly true for sole traders and small businesses.

SoftPOS turns an NFC-enabled Android smartphone or tablet into a secure contactless payment terminal. No additional hardware required.

For a small tradesperson this means:

  • Lower upfront costs
    There’s no need to purchase or lease a card reader, installation of a certified app enables immediate acceptance.
  • Less equipment to carry
    Your phone is already with you. No extra device means less bulk and fewer charging concerns.
  • Faster setup
    Download the app, enable NFC, and you’re ready to accept contactless payments, from day one.
  • All-in-one workflow
    Scheduling, quotes, job notes, invoicing and payment all happen on one device.
  • Reduced risk of forgotten hardware
    No extra kit or card readers, if your phone is charged, you can take payment.
  • Designed for on-the-go work
    Perfect for doorstep repairs, installations, deliveries and on-site quotes.
  • Competitive transaction fees
    Depending on the provider, SoftPOS solutions can offer attractive pricing models.

Selling without limits

Mobile services have redefined what it means to “be open for business.” Sales no longer depend on location, fixed terminals or even permanent premises. With MPOS, businesses can sell wherever opportunity appears on-site, at roadside or pop-up.


The ability to take secure, professional payments anywhere is no longer an advantage, it’s the new baseline for doing business in the field.  Whatever size or application, our team at Castles is ready to guide you through the best option for your business.
