Your card reader (Miura M10) should be on its way to your place of business and once you receive it, you will need to pair it with your smartphone or tablet device (where the ePOS app is installed) using a Bluetooth connection. Once this is done, you are ready to access your product catalogue, add items to the shopping basket and progress the check-out to payments stage. You can accept both card and cash payments with the ePOS App.

How do I create a shopping basket and process cash or card payments?
  • Open our CardAlpha app, and select the Payments from the bottom menu.
  • Assuming that you have already added your store items into our App's ECR - electronic cash register, search and select the items your customer is buying and add them to the App's basket.
  • If you already had entered the SKU and UPC/EAN 13 digit codes in the ECR database, you can scan the product's barcode with our in-built scanner to identify and add the item to the shopping basket.
  • Once all the items are added in the basket, tap on Checkout and then select Cash or Card payment as per your customer's choice.
  • For cash transactions, our App automatically records the details once you confirm the transaction.
  • For card transactions, our App will communicate automatically with your card reader to take contactless, Chip & Pin, or magnetic stripe card payments.  
  • When it comes to printing sales receipts:
    1. You can choose to email a digital receipt
    2. Generate a QR code of the receipt, which your customer can scan using their smartphones' camera

SKU (Stock Keeping Unit) is an identifier for each unique product, generated by a retail business for their own internal use. If you want, you can create and add it in our App for a better inventory management.
  • UPC or EAN is a 13 digit standardised universal code utilised within Europe to identify an individual product unit. You have the option to specify EAN/UPC codes, which you can obtain from your Supplier and add it to the product database.

  • If the item was originally paid for by a card, the correct amount will be automatically refunded to the customer's card which was used for the original payment. And a refund receipt option will be made available.
  • In case of a basket level discount, the App will first prompt you to refund the entire basket, after which, the basket will be re-presented with original quantities, discounts etc. Now you can amend it as required based on the new shopping basket details and proceed to a new check-out..
Which pricing sub-elements determine the Gross Amount to be charged for a SKU?

Retail price per unit (ppu) : This is the original list price of the SKU item before any discounts.

Item level discount % or ID%: This is a percentage discount applicable to the retail price of an item.

Basket level discount % or BD%: It is the percentage discount applied to all items within a shopping basket. If an item discount is already available, the BD% will be multiplied with the ID% to determine final applicable discount.

Net price: It is the Retail price per unit (ppu) less any applicable discounts, multiplied by Quantity

VAT %: This is the applicable VAT %, with the VAT % amount based on what has been supplied during the creation of the Product catalogue.  

Gross price: This is the Net price plus applicable VAT. This is the transaction price which is charged to the Cardholder.
