The program is released by trial before payment. When the program is used for some days, you will be prompted that you need to register the program before you can continue to use it. You can choose the payment scheme that suits you through the official website of OTPOS (https://www.otpos.com), use your company information and contact email address, and then click Pay. After the payment is completed, the system will send an email containing the registration code to your mailbox.
Open the Otpos for retail, and in the bottom-right corner of the Sign In button, you will see the Activate the program link. Click this link and the registration window will pop up. Copy and paste the registration code you received into the registration code text box, enter your company name and contact email address, and then click the Activate button to complete the registration.
