Hmm…i assume you questions was asking

If i use ambank bonuslink credit card at parkson ,do i need to swipe my blue bonuslink member card ?

If this is ur questions ,then the answer is yes
The actual should be
1.use ur ambank bonuslink credit card to make payment (earn bonuslink point from ambank)

2.then use ur blue bonuslink member card to swipe for earn bonuslink point from parkson ,but actually you can use ur ambank bonuslink credit to swipe for earn point ,use it like the blue bonuslink member card ,as this ambank bonuslink credit card is 2 in 1 ,which mean it's a credit card it also a bonuslink member card ,no nid bring blue bonuslink anymore
