Vietnam visa in Singapore via agent

[Atlantil]

Hey
Anyone tried this Singapore travel agent http://www.vietnamvisa.com.sg/ ?
They claim to provide actual visa (not a pre-approval letter) as a separate card that you simply present at the border. The advantage is you can apply on line, pickup the card once it’s ready and then avoid any additional hassle with having the visa stamped into your passport once you arrive in Vietnam.
The agent name is newway enterprise and they seemed to be a proper company (as far as I could verify it via web).
I’ve been to Vietnam before and each time obtained my visa at Vietnam embassy in Singapore. Spent hours searching the web but never heard of such a “visa card”.
Would appreciate any hint
thanks

- Maybe this is new term that agent call a visa.
I know there is 2 documents that airlines consider as visa entry to Vietnam, they only allow check-in flight with these document:
- Real Vietnam visa stick in your passport (conventional visa)
- Visa approval letter that allow the bearer to get visa on arrival at Vietnam airport
