Hi @tothanhtuan,
Integration with a POS (EFT POS) device is currently unavailable in wePOS.
The wePOS is a plugin that is usually used in a physical shop to maintain customers, orders, sales, etc. When a customer comes to the shop and purchases something, he can pay with either cash or a card. In wePOS the card system is manual. When a customer will pay for a product with a card then you have to take the payment through the card sliding machine (EFT). After charging the card, the EFT machine will produce an invoice with the order number and card number. You have to put the invoice number and the last 4 digits of that card number manually into the wePOS to keep track of that sale. Automating the process is unavailable by default at this moment in the wePOS plugin.
I hope this information will help. Thanks!
