Pi 拍錢包

App seems to be very useful, and it is said to be available both in english and traditional chinese. But how can I change it to English? I cannot find any option for that.

「玉山wallet」的widget可以按右上角箭頭顯示載具條碼，也可以設定進入app時先跳出發票載具條碼，「pi錢包」更常用於日常小額消費，widget卻沒有載具條碼，也不能設定進入app後直接跳出載具條碼，使用上不方便，希望能改進，謝謝。另外，如果能支援Apple Watch, 在上面小額支付或發票歸戶，那會再更好些。

I strongly suggest avoiding this payment service until PChome IM’s private key security flaws fixed. A private key for sending app notification is found in PChome’s IM app “IM”. Forged notifications can be correctly delivered to specific user. It is possible that the same flaw exist in Pi app. Thus I suggest prevent this until they securely moved to a new key. ---- previous comment ---- Title: Rejects correct credit card numbers 輸入正確卡號卻畫紅字拒絕 Overall user experience is bad. It's full of UI errors and lacks visual responses even for very basic elements. You often feel it's no response. But no, it's UI failures. For example, there's no cursor when typing. It forbids symbols for passwords by not responding to any symbol you typed as if it's hanged. Not to mention how many times the keyboard just stuck after you finished typing. For security aspects, how can a payment service not allowing symbols in passwords and limits the length to 15 characters? Also there seems some problems in their system, I typed my credit card number but the app refuses to accept, not surprisingly, by not saying what's wrong. I suggest not use this app until it's beta and more stable.
