As someone who has collected official and 3rd party PlayStation memory cards for a hobby, I know a photo showing the back of a PlayStation memory card is far more informative than a picture of the front.
Take these two cards, for example.
Viewed from the front, the average person might assume both to be official Sony memory cards. The cases, front and back, are almost identical down to the smallest detail. But when viewed from the back, it’s easy to see that the real Sony memory card on the left has a chip on the memory card. The fake memory card on the right has round black blobs that substitute for chips.
Official Sony memory cards never substituted chips with blobs, but some official Sony memory cards, mostly the original grays, have two chips inside. Some 3rd party memory cards will have a chip and a blob, but practically every fake or 3rd party PlayStation memory card has a black blob somewhere on the card. The only exceptions being Nyko PlayStation cards and most of the multiple MB memory cards.
Even when in the original packaging, the unsuspecting might think they are purchasing an official Sony PlayStation memory card, when in fact, they aren’t. These two look pretty official at first glance, but notice the one on the right has Psone on the memory card. Official Sony PlayStation memory cards never have Psone on the card.
Collecting PlayStation memory cards has become quite an enjoyable hobby of mine. The diversity of the plain jane 3rd party memory cards is tremendous and there’s just all kinds of licensed collectable memory cards. It might surprise some to learn that the far more interesting cards are generally found in Europe and not Japan.
