Digital products differ in how they are delivered and used. A key activates a product, a gift card provides credit, a subscription grants access for a period, and a top-up adds funds to an account.
Activation key: a code for a specific product
A key usually links a particular game, application or licence to your account. The platform and edition matter: a code for an add-on does not replace the base game, and a key for one store does not become a key for another.
Steam, for example, lets you register compatible keys through its product activation feature. A code that is not intended for Steam will not work there. Source: Steam Support on retail keys.
Look for: the product name, platform, exact edition, region, bundle contents and any required base products. “Game key” on its own leaves too many questions unanswered.
Gift card: value and usage rules
A card may add credit to a service balance or let you make purchases in a particular store. It does not necessarily buy a specific game or automatically start a subscription. Check where it can be redeemed and what the balance can pay for.
Cards have their own terms: purpose, region, currency and sometimes an expiry date. Do not apply one platform’s rules to another. Even similarly named cards from one brand can be different products.
Subscription: access for a defined period
The main details are the plan, access period and activation method. Find out when the period starts: at purchase, delivery or activation. Check whether the offer is available to existing users and what happens when the period ends.
A subscription can be prepaid or renew automatically. These require different account settings. The word “month” does not guarantee that there will be no future charges: check the plan terms and account settings.
Balance top-up: funds within a service
A top-up adds funds under the platform’s rules. The amount paid to the seller, any fee and the amount credited can differ. Before paying, you should know which balance will increase and by how much.
Check which recipient details are required and verify them carefully. If you are asked to hand over access to an account, stop and establish why: sharing account access is a separate risk, not a normal requirement of every top-up.
How to compare two offers
| Format | Main question | What to check |
|---|---|---|
| Key | Which product does it activate? | Platform, edition, region |
| Gift card | Where can the value be spent? | Purpose, country, currency |
| Subscription | What access, and for how long? | Plan, start date, renewal |
| Top-up | How much reaches the balance? | Service, recipient, credited amount |
Compare prices only once these details match. A cheaper offer might be a different edition, a shorter period or a product with conditions that do not suit your account.
