Sony has issued a clarification on the news that recently surfaced which suggested that only one PlayStation Network ID could be used per PlayStation Vita.
As it turns out, multiple PlayStation Network IDs can be used on a single PlayStation Vita, but you’ll be required to have mutliple memory cards to do so. Crystal MacKenzie, associate brand marketing manager at Sony, told Wired’s Game|Life in a statement:
“Your PSN ID is bonded to your memory card and your memory card is bonded to your Vita,” MacKenzie said. “So if you wanted to change different PSN users but use the same memory card, you would need to go factory reset.”
You can use additional memory cards to create new PlayStation Network IDs or import existing ones, and you can even tie the same PSN ID to multiple memory cards, MacKenzie explained.
If you want to, say, import one PlayStation Network ID to another, you’ll still have to reformat the memory card you’re importing to if it already has a PSN ID attached to it.
Unless you’re content with going with the low-end memory card, having to purchase multiple memory cards to store multiple PSN IDs can be expensive. Sony recently revealed the pricing in the US for their lineup of memory cards, and they put the 4GB model at $29.99; the 8GB model at $44.99; 16GB for $69.99 and 32GB for $119.99.
