Why does Taiwan's e-invoice 手機條碼 (mobile barcode) start with a slash (/)? How many characters is it?

Question

Weirdo · Accepted Answer

A 手機條碼 is 8 characters, and the first is always a slash (/). The other 7 are digits, capital letters or symbols, for example /E7E6888. It is the common e-invoice carrier of the Ministry of Finance's e-invoice platform.

The Ministry of Finance e-invoice platform describes the mobile barcode as a one-dimensional barcode generated from a mobile phone number plus an email address, made of "/" and 7 letters, digits or symbols, for example /E7E6888. So it is not your phone number itself, but a code created when you register.

Register in the 統一發票兌獎 app (tap "register a new account") or on the Ministry of Finance e-invoice platform. After that, the app shows the barcode; show it at checkout and the cloud invoice is saved to the carrier. The platform also suggests phone Widgets, and on iOS a barcode pass in Apple Wallet, for faster display.

In the app's carrier-linking feature you can bind cards such as EasyCard, iPASS, credit cards and membership cards to your mobile barcode and manage the cloud invoices in one place. Under the Ministry's notes, if you show the mobile barcode together with another carrier, the mobile barcode is used to store the cloud invoice.
