Reader compatibility and manufacturing qualification

Validate the modulation, bit rate and identifier format with the installed low frequency reader. NFC phones do not read 125 kHz credentials. For programmed formats, agree a sample identifier and confirm how the host system interprets it.

Select a finished product above for format specific guidance on dimensions, attachment, antenna placement and operating conditions.

State your required product model, IC order code, printed identifiers, encoding format, initial volume and delivery destination. Roxtron confirms the complete production specification and quotation before manufacture.
