What is the correct way of writing two MSc degrees on a business card? If someone would have obtained two MSc degrees, how do you put that on a business card?

I myself have two MSc degrees from a Dutch university. The degrees are Computer Science which gives me the Dutch title ir, and Science Communication which gives the Dutch title drs. Both degrees are internationally an MSc (as indicated on my diplomas). I know that in Holland I can use the following:


drs. ir. John Doe


Since the Dutch titles are confusing in international use (especially the drs part), I would like to use the international format on my business card. For one MSc I know that it is written internationally like this:


John Doe, MSc


However, how is the international format for two MSc degrees?
How about


  John Doe, MSc (Comp. Sci.), MSc (Sci. Comm.)


? (Then again, this could look pretentious. Proceed with caution.)

Unfortunately, the relevant Wikipedia article is not highly informative, and anyway it is flagged as "citations required" and specific to the UK:


  Where two different postgraduate qualifications with the same name
  have been obtained (for example two different postgraduate MAs from
  King's College London and University of Sussex), this can be indicated
  by using one degree postnominal, and the abbreviations of the two
  awarding bodies in parentheses, sometimes joined by the Latin "et" (or
  with an ampersand), e.g. "Jane Smith MA (KCL et Sussex)", and not
  "Jane Smith MA MA". However, when qualifications with the same name
  have been gained through different routes (for example an MA from
  Oxford University converted from a Bachelor of Arts, and a studied and
  examined postgraduate degree from King's College London these are
  listed separately with the institution only listed after the
  non-examined qualification (e.g. "Jane Smith MA(Oxf) MA", and not
  "Jane Smith MA (Oxf et KCL)").
