No idea if it’s best, but last year I got a LINE Pay card from CTBC (link, although who knows how long that’ll remain valid). No charge, unlike the NT$2,400/year for the Citibank one I was getting airline points on. LINE points worth 1% of the value of all domestic purchases, worth 2.8% on all international purchases - so that’s actually higher than the international surcharge. At some point I’ll have to figure out if it makes more sense for me to use this card or my Canadian card when I’m in Canada later this year.
You accumulate points and as far as I can figure can basically use them anywhere that takes LINE. Not exactly cash back, but close enough. It’s paying for a restaurant meals once in a while.
I’ve also got that card connected to the Carrefour and PXMart apps on my phone, and use the apps to pay at those stores; it’s also connected to JKOS for power bills and taxi rides. I’ve grown fond of using LINE to pay for things, but once or twice that habit has made things very mildly inconvenient for me because I’ve been out with my phone, without my wallet, and that’s limited restaurant options.
There were a bunch of sign-up bonuses as well, including I think a suitcase that disappeared into my wife’s guanxi networks, but I don’t think those are significant factors. In the first few months there were tons of “Extra LINE points for shopping here!” deals - I’m not sure if those have diminished over time, or I turned off annoying alerts, or my wife got tired of telling me about deals that didn’t interest me. (The browser window I had open for the link above is now scrolling through lots of special LINE offers, so I guess those are still happening!)
Only negative is that I can’t currently pay the bill online, so I’m back to withdrawing money from an ATM and promptly handing it to over to pay the bill. I think that’s more due to limits with my main bank (Post Office, because that’s what my job requires) rather than with CTBC.
Caveat: chosen by my wife and I’m assuredly missing something, such as how perhaps fees will kick in later, or point rebates will be reduced.
Versus the old Citibank card: I don’t even know what this is - information about it hasn’t been available on their website in years now. Price was $1,200 per year, jumped up to $2,400 a few years ago. I did collect enough points to buy a one-way business class ticket across the Pacific, but I’ve now got almost all my recurring bills off that card and onto CTBC. What with COVID I’m a lot less interested in airline points than I used to be. Plus using them can be such a pain.
