I'm now more interested in the question :which payment type WHICH CANNOT BE EASILY TRACED has the best cashback/benefits? I find my options much more limited. For example, can they trace Alipay? Can they trace an Octopus which is not registered?
Convience always comes with a price. No such thing as a "free" service (ie. cc's, payme, octopus)
Up north, such is their advanced use of 'big data' these days, there are probably CCTV's which could capture your entry through subway turnstiles. All they need is two entries to correlate (throw in a third for good measure) and it would be pretty easy to figure out which "anonymous" subway card you are using and tag you permanently.
Stick to single use tickets if really paranoid... though that probably only raises the bar slightly.
Guys may I seek advice on the overseas spending category
1. If my online purchase is not in HKD does it get categorised as A) online or B) overseas spending?
If this answer is B) then,
2. Is getting a CC with 0% handling fees for overseas spending worthwhile? (it seems that handling fees can be up to 3%?)
Appreciate any advice!
Having a bit of a blond moment with my maths.
So If I opt to pay my rent with Citi PayAll with Citi Prestige it seems to work out at 2 points per HKD. So for example if my rent is HKD20k a month I will get 40k points. Citi will charge HKD200 per month (so 1%).
Based on Citibank's website the standard rate of conversion from points to cash rebate is 180 points per 1HKD. I think this works out at roughly 1%, so setting off the Citi service fee.
However if you convert above a certain amount (I think its something like HKD825k points) then the rate is 165 points per 1HK. Sorry for being a bit dumb, but what would that make the rebate amount?
