A Strap is an IC chip mounted on a film which also has an adjacent area of conductive material next to the IC thereby forming a raw elecode.
Straps are supplied from IC chip production makers and by on rolls or sheets and are utilized widely as one of supply method of IC chip with roll or sheet type. Common specification is formulated by JEDEC(Joint Electron Device Engineering Council).

Strap is electrical bonded IC chip and antenna.
Strap can be card and label products via 2nd process.
Also, It is possible to be adapted to each usage environment such as type for metal, for dry-cleaning and so on.
Source Tagging means direct attachment of RFID or RFID strap onto products or packages during their production level or distribution level.
HF (High Frequency): radio frequency of 3MHz to 30MHz.
In RFID, 13.56MHz is universal.
UHF (Ultra High Frequency): radio frequency of 300MHz to 3GHz.
