ID cards are the physical credential a security system hands to each person: proximity and smart cards that open doors and log presence, printable PVC cards that a badge printer turns into photo ID, and the combination cards that do both jobs on one badge. Every access control system and every badge program consumes these by the box.
The access control system dictates the card: proximity and smart card families differ by technology and format, and the card must match what the door readers speak - order against the installed system's specification, including the facility code and numbering details the security office manages. For printed badges, card quality matters to the printer; badge printers specify the card stock they warrant. Combination cards should be verified against both the readers and the printer before a volume order. Buying credentials in planned batches keeps numbering coherent and onboarding stocked. COLAMCO supplies ID cards and credentials for business, government, and education badge and access programs.
