Why I need to authorize the contact list?

In order to optimize TNG Wallet's services, TNG requires your authorization to access your contact list. TNG Wallet only accesses your contact list when you use certain services, such as conducting P2P transfers or gifting e-tickets and coupons. TNG will not store any information obtained from your contact list.

If you still wish to remove the authorization, select "Wallet HK" from your smartphone's settings and then turn off the authorization for your contact list.
