In the beginning, the Blockbuster gift card replaced gift certificates that were being counterfeited with recently introduced color copiers and color printers. Blockbuster's first gift card transactions were processed by what was then Nabanco of Sunrise, Florida.

Gift cards thus are generally not stored-value cards as used in many public transport systems or library photocopiers, where a simplified system with no network stores the value only on the card itself. To thwart counterfeiting, the data is encrypted. The magnetic strip is also often placed differently than
