Unlike traditional credit cards, these are not physical objects but <b data-path-to-node=\"8\" data-index-in-node=\"211\">cryptographic tokens<\/b> generated on-demand via an Issuing Bank\u2019s API.<\/p>\n<h3 data-path-to-node=\"9\">The Anatomy of a Temporary Credential<\/h3>\n<p data-path-to-node=\"10\">Every single-use card consists of three dynamic components that distinguish it from legacy cards:<\/p>\n<ul data-path-to-node=\"11\">\n<li>\n<p data-path-to-node=\"11,0,0\"><b data-path-to-node=\"11,0,0\" data-index-in-node=\"0\">Dynamic PAN (Primary Account Number):<\/b> A unique 16-digit number that is mapped to a secure ledger rather than a direct bank account. Once the transaction is authorized, this number is \"burned\" in the issuer's database, rendering it useless for future attempts.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,1,0\"><b data-path-to-node=\"11,1,0\" data-index-in-node=\"0\">Volatile CVV2:<\/b> The three-digit security code is generated using a time-based algorithm. Even if a merchant stores the CVV2 (against PCI standards), the code expires within minutes of the transaction.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,2,0\"><b data-path-to-node=\"11,2,0\" data-index-in-node=\"0\">Algorithmic Expiry:<\/b> These cards are typically set to expire within 24 to 72 hours of issuance, ensuring that \"Pre-Authorization\" holds do not leave the credential active for long-term exploitation.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"12\">The Role of Tokenization in 2026<\/h3>\n<p data-path-to-node=\"13\">In 2026, one-time cards utilize <b data-path-to-node=\"13\" data-index-in-node=\"32\">EMVCo Tokenization Standards<\/b>. When you use a Buvei card, the merchant never sees your \"Real\" funding source. They see a surrogate token.

A one-time card prevents this \"testing\" phase from ever leading to a secondary charge.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"20\">Subscription Defense and \"Gray-Market\" Billing<\/h3>\n<p data-path-to-node=\"21\">Many modern merchants utilize \"Dark Patterns\" to make cancellation difficult.<\/p>\n<ul data-path-to-node=\"22\">\n<li>\n<p data-path-to-node=\"22,0,0\"><b data-path-to-node=\"22,0,0\" data-index-in-node=\"0\">Forced Continuity:<\/b> By using a temporary card for a \"Free Trial,\" you effectively place a \"Dead Man's Switch\" on the subscription.
