• 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.

• This function is useful for Restaurants and Cafes, for example,  where customers may give an order for food and drinks initially and a bill/check is presented later forpayments.
  
• If you don't wish to checkout the customer  basket immediately, you can then save the basket with selected items, under a basket name (for example with the customer's name or a table number in a  restaurant) and choose to checkout later. To access this function, you will need to tap the shopping cart icon on the bottom left of the screen.
• To retrieve a saved basket, you can tap the shopping cart icon from the Payments menu option and then select load basket. You will be presented with a list of saved baskets to choose from, and to proceed to check out.

• Certain merchants especially in the Restaurants and Cafe verticals may require an additional functionality for tips/gratuity payments (the terms tips and gratuities are being used interchangeably here).CardAlpha's ePOS treats tips and gratuities  as optional or discretionary service charges, paid voluntarily by customers. As such they are treated as outside the scope of  VAT by the ePOS (as per UK VAT notice 700, Section 8.14).
  
• To set-up tip/gratuities on the ECR, you will need to create the the tip/gratuity as an item type in a manner, similar to how basket discounts are set-up (but of course the tips/gratuity will work in an opposite manner to basket level discounts). In the description field, you can enter any name for the tip, for example "Tip 10%". You can leave the SKU, EAN/UPC and category fields blank. Under the Unit type field choose Tip/Gratuity % as an option and enter the numerical value of the discount. To enter 10% tip, just enter the number 10. And save the entry.
  
• The tip/gratuity % will now be available in the ECR as a product type, with its description field and can be selected alongside any normal products/service to create the order basket.
  

• Open our CardAlpha app, and select the ECR from the bottom menu.
• Click on the "+" button, and add product descriptions with images, prices, VAT, and inventory details. To upload many items with one click, go to Help and request for batch upload.
• While creating your ECR, please note the relative importance of SKU and UPC/EAN (13 digit) codes. 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. During sales check-out you can scan the barcode with our in-built barcode application to identify the item and add it to the shopping basket.

• Open our CardAlpha app, and select the Payments from the bottom menu.
• Click on the Transactions in the top right corner.
• Pull out the specific transaction details (for the transaction to be refunded) by using the amount, date, or a receipt number.
• Once the transaction has been located, the relevant basket items with their quantities will be available on the screen.
• You can issue a full or a partial refunds by using the “-“ (minus) to decrease the quantities of the items.
• If the original item was paid for in cash, the App will instruct you to refund the cash amount and provide you with an option to generate a receipt.
• If the item was originally paid for by a card, the ePOS app will communicate directly with the card terminal to process refunds. A supervisor password is required on the card terminal for processing refunds. Your welcome letter will contain details of the supervisor login and password.  
  
• Please note if the original transaction contained 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 checkout.
  

Retail price per unit (ppu) : This is the original list price of the SKU item before any VAT or 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 applied together with the  ID% to determine the 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 by the user while setting up the item on the catalogue.

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

We round off any list price, discounts applied and VAT amounts to the nearest penny. If the fraction of the penny is 0.5 or more, we round up to the next whole penny. If the fraction of the penny is below 0.5, we round below. With this rule, if any amount is 45.666, we will treat the rounded-off amount as 45.67. If on the other hand, the amount is 45.454, we will treat the rounded-off amount as 45.45.
