How to Choose the Right RFID Card in India
Choosing an RFID card starts with the system that will read it. RFID cards can look similar on the outside while using very different frequencies, chips and communication methods. This guide explains the main RFID card types used for identification and access applications and the information to confirm before placing a bulk order.
What Is an RFID Card?
An RFID card is a contactless identification card containing an RFID inlay, chip and antenna. When the card is presented to a compatible reader, the system identifies the card and can use that identification for access control, attendance, membership, hotel access, parking, tracking or another configured workflow.
The correct card is determined by the reader technology and the application. A card should not be selected by appearance alone.
RFID Card Types
125 kHz Proximity RFID Cards
125 kHz proximity cards are commonly used for employee access, attendance, parking and other low-frequency identification systems. They are appropriate when the installed readers are designed for 125 kHz proximity technology. See our 125 kHz Proximity RFID Cards.
HF RFID Cards at 13.56 MHz
13.56 MHz HF RFID cards are used across access control, attendance, membership, credentials and other short-range contactless applications. The required chip and memory depend on the reader and software system. See our HF RFID Cards.
MIFARE RFID Cards
MIFARE is a family of contactless card technologies used in compatible 13.56 MHz systems. MIFARE Classic 1K and 4K cards are options where the installed reader and application support those formats. See our MIFARE 1K & 4K RFID Cards page.
UHF RFID Cards
UHF RFID cards are designed for longer-range identification with compatible UHF/RAIN RFID readers. They can be useful for parking, vehicle identification, attendance at controlled entry points and other applications where the card must be detected from a greater distance. See our UHF RFID Cards.
NFC Cards
NFC cards operate at 13.56 MHz and are designed for short-range interactions with compatible NFC-enabled phones or readers. Common uses include digital business cards, information sharing, access and branded tap experiences. See our NFC Cards.
Dual Frequency RFID Cards
Dual-frequency cards combine two compatible RFID technologies in one physical card. They are useful where one credential needs to support two reader environments, such as legacy proximity and HF access systems. See our Dual Frequency RFID Cards.
What Should You Confirm Before Ordering RFID Cards?
- Reader technology: Confirm the frequency and card technology supported by the reader already installed.
- Chip and memory: Confirm the required chip type, memory and data format where applicable.
- Application: Define whether the card is for access, attendance, hotel room access, membership, parking, identification or another workflow.
- Card construction: Select the required material, finish, dimensions and thickness.
- Printing and personalization: Specify logos, artwork, photographs, names, serial numbers, barcodes or QR codes as required.
- Encoding: Confirm whether cards need pre-encoding and what information the system expects.
- Quantity and delivery: Share the project quantity and required delivery schedule before production.
RFID Card Materials and Customization
RFID cards can be supplied in different constructions depending on the application and required appearance. PVC is common for everyday identification and access credentials. Wood and other specialty constructions can be selected for hospitality or premium branding projects where the card’s visual presentation is important. Custom printing and personalization should be specified together with the selected RFID technology.
Which RFID Card Is Right for My Application?
| Requirement | Card Type to Evaluate |
|---|---|
| Existing 125 kHz access-control reader | 125 kHz Proximity RFID Card |
| 13.56 MHz access or identification system | HF RFID Card |
| Compatible memory-based HF system | MIFARE RFID Card |
| Longer-range identification with UHF reader | UHF RFID Card |
| Tap interaction with NFC phone or reader | NFC Card |
| Two compatible RFID systems in one credential | Dual Frequency RFID Card |
| Hotel guest room access | RFID Hotel Key Card |
RFID Cards for Bulk and Custom Projects
Corona Card Technology supplies RFID cards for corporate, hospitality, education, retail, events, transportation and other identification projects. For a quotation, provide the required card type or existing reader details, quantity, artwork, material preference and encoding requirements. These details allow the card specification to be matched to the actual system before production.

Frequently Asked Questions
Can I use any RFID card with my reader?
No. The card technology, frequency, chip and encoding must be compatible with the reader and software system.
Are RFID cards customizable?
Yes. Depending on the card construction, cards can be supplied with custom branding, artwork, numbering, photographs, barcodes, QR codes and other personalization requirements.
Which RFID card is best for access control?
The correct choice depends on the access-control hardware. 125 kHz proximity cards are used with compatible LF readers, while many 13.56 MHz systems use HF or MIFARE card technologies.
Can RFID cards be supplied in bulk?
Yes. Bulk supply is available for project requirements. The required technology, quantity, artwork and encoding specifications should be confirmed before production.
