Smartrac has launched Dual Frequency Prelam, its latest RFID inlay suited for convenient public transport applications. The new product combines one pre-laminated inlay (prelam) with two secure contactless chips, one working in high frequency (HF) and the other in ultra-high frequency (UHF), in a single card.


The capability of such a dual frequency card allows transport operators to select the type of revenue collection method that is appropriate at the point of entry. For example, transport operators can allow for hands-free or Be-in-Be-Out (BIBO) fare collection in very large human traffic channels or for physically challenged commuters. In standard entry or exit, Check-in-Check-Out (CICO) fare collection reader terminals can be deployed.

“The benefits of Smartrac patented technology in this product include very strong bonding of the different layers of sheets in the PRELAM, anti-crack design to prevent chip crack during end lamination and harmonized tuning of HF antenna and UHF antenna,” explains Daniel Lim, global head of Business Line Transport, Secure ID and Transactions Business Division. “Card manufacturers can fully customize their Dual Frequency Prelam’s depending on the required write/read performance of the contactless chip card.”

Available in PVC, PC, PET-G or Teslin, Smartrac offers Dual Frequency PRELAM with several combinations of secure and popular contactless chips: For HF, customers can choose between NXP MIFARE DESFire EV2, Sony FeliCa RC-SA01 4KB or the Infineon myD4Move chip. The UHF chip offerings include NXP UCODE DNA or Impinj Monza.
