For UK and Ireland security teams
Use Keysy only with written permission from the credential owner or system operator. It can support authorised access-control assessments, physical security reviews and training where the relevant 125 kHz credentials are in scope. Confirm compatibility before testing, as credentials operating beyond the supported read distance or using other frequencies are not supported. Prices are shown in GBP or EUR, with USD also available. VAT is calculated at checkout. Review applicable rules on access-control tools, radio equipment and the handling of copied credentials before use.
