Security envelopes with pin codes for VTB24 plastic cards

Recently I ordered two plastic cards in VTB24. I received them in a week and in order not to confuse PIN codes, I folded the cards in envelopes with the last ones, each in an envelope with the number of this card.

When I needed one of the cards to make it easier to remove, I cut the envelope along and unfolded it completely, took out a card and a sheet with a pin code.

My attention was attracted by a black shiny rectangle printed on the envelope on the inside. At first I thought that this was an additional protection from viewing the envelope to the light, in order to find out the pin code, but later I realized that the application of dye is identical, probably, that is used to make copy paper (carbon paper) and is used to print pin the code on the sheet enclosed in the envelope with the fact that the envelope is sealed.

And I was interested in this coverage by the fact that the pin-code of my card was clearly visible on it !

The inscription on the envelope reads about the following: - “The client is responsible for the safety of the pin-code in secret. Do not tell anyone and do not give your personal PIN. "

I remember how I opened the envelopes of my previous plastic cards. Opened, pulled out a piece of pin-code and threw the envelope. In those moments I was not embarrassed by the presence of my address and name on it. And now I will most likely destroy these envelopes in order to avoid possible troubles, which fortunately have already bypassed me and many of those who deal with these envelopes in the same way as I throw them away.

I reported to VTB24 about this issue. Today they called me back, thanked me for the information and that it was transferred “where necessary”, but I think that the printing technology will not change soon. And in other banks, most likely, a similar pin code printing system is used.

Be carefull!
