Barcodes are machine-readable codes that represent data in a visual, rectangular format. Traditional linear barcodes (like those on supermarket products) store information horizontally. QR (Quick Response) codes are two-dimensional barcodes that store information both horizontally and vertically, allowing them to hold much more data.
For UK small businesses, both technologies offer practical applications. Barcodes are ideal for product identification and inventory tracking. QR codes excel at customer-facing applications like payments, menus and marketing because they can be scanned by any smartphone camera.

Barcodes for Inventory Tracking
Barcode scanning transforms inventory management from a manual, error-prone process into a fast, accurate operation. Instead of typing product names or SKUs, staff simply scan the barcode to identify the product, check stock levels or process a sale.
Aphelios Software supports barcode scanning using your phone camera or a dedicated barcode scanner. You can scan products to update stock, process sales, perform stock counts and retrieve product information instantly. This dramatically reduces human error and speeds up transactions.
For UK businesses managing physical stock, barcode scanning is not a luxury: it is essential. Whether you have 50 products or 5,000, barcodes ensure accurate tracking and fast checkout.
QR Codes for Customer Payments
QR codes offer a simple, low-cost way to accept customer payments. Instead of buying a card reader, you generate a QR code that customers scan with their phone to pay. This is particularly valuable for UK market traders, pop-up shops, cafes and restaurants.
Aphelios generates QR codes for payments, invoices and digital menus. Customers scan the code with their phone camera and complete the payment through Stripe. No card reader hardware is required: just print the QR code or display it on a screen.
QR payments are growing rapidly in the UK. Customers are increasingly comfortable paying by scanning, especially for small transactions. Offering QR payments gives your business a modern, frictionless checkout experience.

Can I use my phone as a barcode scanner?
Yes. Aphelios Software supports barcode scanning using your phone camera. Simply point the camera at the barcode to scan it. No dedicated barcode scanner hardware is required.
How do QR codes work for payments?
QR codes for payments contain a payment link. The customer scans the code with their phone camera, which opens a secure payment page. They complete the payment using their preferred method.

Barcodes store data in one dimension and hold up to 20 characters. QR codes store data in two dimensions and hold up to 7,000 characters. Barcodes are ideal for product identification. QR codes are better for customer-facing applications.

No. Aphelios Software supports barcode scanning using your phone camera. For high-volume environments, a dedicated barcode scanner can speed up scanning, but it is not required to get started.
