About payment
We accept PayPal now and keep updating Shopify's other payment methods.
PayPal
PayPal is an online account-based system that lets anyone with an email address send and receive online payments using their credit card or bank account. You can use it at signalthree.com to pay safely, easily, and quickly. During the ordering process, you can also open a PayPal account if you don't have one.
Card Payment
If you choose to pay with an international bank card, please note that all information must be entered in English.
If you select a local bank card for payment, the system will redirect you to your mobile banking app for payment confirmation when the website initiates the payment request.
Cash Payment
If you choose QR Code payment, please note that our system currently supports only the following banks:
- KASIKORNBANK PUBLIC COMPANY LIMITED
- UNITED OVERSEAS BANK (THAI) PUBLIC COMPANY LIMITED
- Siam Commercial Bank PCL
