The Digital POS Module serves as a swift point of sale terminal, facilitating quick and convenient payments. When a merchant initiates a transaction, a QR code is generated. The customer can then scan the QR code using their Boompay account and make an instant payment. Additionally, a receipt can be printed for record-keeping purposes. The installation and setup process is incredibly simple. The Digital POS Module acts as an add-on feature to enhance the functionality of Boompay.
