Dual frequency card
Dual frequency card introduction
The dual-frequency card means that the chips of two different frequency bands are packaged on one card, the low frequency frequency is 125KHz, the high frequency frequency is 13.56MHz, the ultra high frequency is 860MHz-960MHz, and the dual frequency card is the two frequency bands. Cards are packaged together, such as high-frequency and ultra-high-frequency packaging, that is, it can be safely identified at close range or remotely, and the current distance can reach about 6 meters.
Dual frequency card features
Dual-band card can solve a special technology that cannot use single-band cards in some fields, such as campus cards, government, agencies, etc. Dual-band cards are “one-card multi-purpose”, which has the advantages of magnetic stripe card and IC card. . The card adopts non-contact design and is directly deducted by radio frequency mode, which is safe, convenient, wear-resistant and fast.
Dual frequency card combination
1: UHF plus high frequency dual frequency composite card
The dual-band card is a combination of UHF (915MHz) + HF (13.56MHz) antennas. They all use sensitive etched antenna technology. They can be packaged into PVC standard label cards or packaged in cheap paper. label.
2: UHF plus high frequency plus low frequency tri-band composite card
The tri-band card is composed of UHF (915MHz) + HF (13.56MHz) + LF (125KH) antennas in three frequency bands. One tag card can realize RFID operation in three different frequency bands, which is very convenient for users to manage.
3: high frequency plus low frequency dual frequency composite card
The dual-frequency card is composed of an antenna of two frequency bands of HF (13.56MHz) + LF (125KHz), and can be made into an ISO card or a 1.05mm medium-thick card and a 1.8mm thick card.
