Introduction to dual-band cards
A dual-frequency card refers to two different frequency bands of chips packaged on a single card: low-frequency 125KHz, high-frequency 13.56MHz, and ultra-high frequency 860MHz-960MHz. Dual-frequency cards package cards from any two frequency bands together, such as high-frequency and ultra-high-frequency packages, allowing for secure recognition both at close and long-distance ranges, with a current distance of about 6 meters.

 

Features of dual-band cards
Dual-frequency cards can solve a special technology in certain fields where single-band cards cannot be used. For example, in campus all-in-one cards, government, and government agencies, dual-frequency cards are "multi-purpose," offering both the advantages of magnetic stripe cards and the characteristics of IC cards. This card features a contactless design and allows direct payment via RF mode, featuring safety, convenience, wear resistance, and speed.

 

Dual-frequency card combination method
1: Ultra-high frequency combined with high-frequency dual-frequency composite card
This dual-frequency card combines UHF (915MHz) + HF (13.56MHz) antennas, both using a highly sensitive etched antenna process. They can be packaged as PVC standard label cards or as inexpensive paper labels.

2: Ultra-high frequency combined with high frequency plus low frequency tri-frequency composite card
This tri-band card cleverly combines antennas from three frequency bands: UHF (915MHz) + HF (13.56MHz) + LF (125KH). A single tag card can operate RFID across three different frequency bands, making it very convenient for users to use and manage.

3: High-frequency and low-frequency dual-band composite card
This dual-band card combines antennas in the HF (13.56MHz) + LF (125KHz) frequency bands and can be made as ISO cards or 1.05mm medium thickness cards and 1.8mm thick cards.

Dual-frequency card manufacturing process
01. The standard size of dual-frequency cards is 85.5mm x 54mm, with rounded corners. It can also be made in other sizes.
02. Dual-frequency cards can print single-sided or double-sided printing, using screen printing or offset printing (CMYK four-color printing).
03. Each dual-frequency card can be sprayed with different numbers, PIN codes, or text.
04. Dual-frequency cards can add signature strips or writing boards (areas where manual writing is possible).
05. Dual-frequency cards can be equipped with low-density or high-density magnetic strips (three-track magnetic strips) according to customer requirements.
06. Dual-frequency cards can be embossed, with gold or silver stamping on the embossed codes.
07. Round or strip holes can be drilled on dual-frequency cards.
08. Dual-frequency cards can be coded and scratched on shoes (commonly used for recharge cards, phone cards, lottery cards, etc.).
09. Dual-frequency cards can be printed with various types of barcodes.
10. The numbers on dual-frequency cards can be arranged sequentially, or personalized or irregular numbers can be used.
11. Dual-frequency cards can be made into square, round, or any other irregular shapes.
12. The background color of dual-frequency cards can be made in imitation gold or imitation silver.
13. Gold or silver can be stamped on the dual-frequency card.
