Payment Asia's Own Mobile Payment Application

Payment Asia’s Own Mobile Payment Application – PA Pay

Our mobile payment solution is designed especially for merchants, and currently supports Alipay, WeChat Pay and UnionPay QR Code payments. PA Pay is the perfect partner for merchants from different industries to conduct business through our mobile and QR code payment system. The PA Pay App also supports mobile payment of Hong Kong merchants in physical stores. For clients who own brick and mortar stores, you can receive immediate notifications of mobile payment and transaction reports when you use PA Pay. This facilitates brick-and-mortar merchants to understand the transaction status instantly and reduce waiting time.

In comparison to credit card transactions, by using PA Pay – a mobile app, you are now offered a mobile payment solution with a shorter settlement period which effectively lowers your operation costs. Generally, we can achieve T+2, and you will receive the settlement in 2 days once you have met the minimum settlement thresholds. However, different mobile payment gateways may have different settlement times and minimum settlement thresholds. You can check the relevant settlement records at the merchant platform.

PA Pay includes both RMB eWallet and HKD eWallet for mobile payment gateway (Alipay, WeChat Pay and UnionPay), all transactions are settled in HK Dollars. In addition, this mobile payment solution is suitable for all types of Hong Kong merchants.

The definition of e-business is being broadened at the same pace as the development of social media. We, as a company are following the trend closely, and are aggressively developing our digital marketing business in both Mainland China and Hong Kong. Other than our mobile payment app – PA Pay, our one-stop e-business solution includes the management of social media accounts and profile pages, with the help of our big data analytic system and Artificial Intelligence (AI) technology.

1. How to use our mobile payment HK app for collection?

First, after opening PA Pay with a POS terminal or mobile phone, you will see that there are three specific pieces of information you need to enter, which are the merchant ID, the POS terminal ID and the password. You can find the login information in the email sent by PA Pay with the subject “Congratulations”. You can then fill in the required information, and start making mobile payment collections. 

QR code payment collection procedures:

(Pull mode)

  1. Step 1: Press the middle button and enter the amount.
  2. Step 2: Click “Confirm Payment”, and select the used payment method. 
  3. Step 3: Show it to the customers for scanning to conduct QR code payment in Hong Kong.
  • The green screen now displayed means that the QR code payment has succeeded. 
  • The blue screen means the transaction is in progress.
  • The red one means the QR code payment transaction has failed. 

2. What documents are required for application?

  1. Business Registration Certificate (BR)
  2. Certificate of Incorporation (CI)
  3. Acceptable residential address and identify proofs of directors and holders
  4. A monthly bank statement issued within the last 3 months
  5. Photos of products and store
  6. Other business related documents

3. Why does the mobile payment transaction’s status appear to be pending or failure?

Whether it is mobile or QR code payment in Hong Kong, if pending status appears, it means that the payment request has been sent to the payment provider. If the order remains in this state for more than 30 minutes, you can directly treat the mobile payment transaction as a failure. If the POS machine/ PA Pay App displays ‘failure’ when customers make mobile payment in Hong Kong, the main reasons are usually because the customer’s wallet balance is insufficient, the transaction limit has been exceeded, the identity authentication level is problematic, or there may be mobile phone security issues, such as Touch ID or Face ID cannot verify identity, etc. If the merchant encounters these cases while using the mobile payment gateway, they should remind the customer to check their e-wallet.

4. How can I get the refund after using the mobile payment HK app - PA Pay?

If the customers want to refund, the transaction of that day can be refunded instantly by the POS terminal. You can click “History” and select the transaction that we want to refund first through our mobile payment solution.   If you confirm that the transaction information is correct, click “Refund”. Enter the account password and press “Confirm”. After that, the refund can be made. The PA Pay App can only refund the mobile payment transaction or the QR code payments on that day. If the refund transaction is more than one day ago, you need to process the refund in the merchants backstage. 

5. How can I view the transaction record and report through the mobile payment app - PA Pay?

If you want to check the transaction record of that day through our mobile payment solution, you can click “History”. After that, you will see transactions from different mobile payment gateway with different transaction status. If you want to view the previous transactions, select the appropriate year, month and day under “Date”, and it will be displayed clearly.    If you want to check the transaction report of mobile payment and QR code payment system, you can click “Report”. The screen will show the transaction volume of all mobile payments within the week. Choosing one specific day, the transaction details of a single day can be printed out by the POS terminal. Also, email or WhatsApp messages can be sent, or save screen capture to your mobile phone. 

6. How can I apply for an additional POS terminal for QR code payment?

If your store wants to apply for an additional POS terminal to conduct QR code payments in Hong Kong, you can send email to us. We will add a new terminal number to you, and send the new POS terminal to you within 7 working days.
