The types of access control cards can have identical designs but different chips, frequencies, or encoding methods.
Incompatibility can result in no response, errors, or failure to unlock the door.
Here are the key differences between card types and the factors you need to consider before placing your order.
What Are Access Control Cards?

An access control card is used to unlock a secured door or gate.
Once the reader identifies the card, it sends the card information to the controller. The controller then verifies your authorization to open the door.
The system consists of a card, reader, controller, software, and electronic lock.
Some cards may also have other functions, such as tracking attendance, unlocking elevators, managing parking, and making payments.
Main Types of Access Control Cards

Card names may refer to the card’s technology, frequency, chipset, manufacturer, or design.
MIFARE is an example of an RFID card family. However, not all RFID cards are MIFARE cards.
Magnetic Stripe Access Cards
Magnetic stripe access cards are called “swipe cards” and carry an access code in Magnetic Stripe located on the back of the card.
The card is swiped through the card reader.
There are two types of magnetic stripes: LoCo and HiCo. LoCo stripes have low magnetic strength, while HiCo stripes have high magnetic strength and are more durable.
They’re inexpensive but less secure than other cards.
Proximity Cards
Proximity cards, also known as contactless cards, operate near the reader.
These cards typically operate at a frequency of 125 kHz and transmit a predefined number for identification purposes.
EM4100, TK4100, T5577, and HID Prox are some common types of proximity cards.
RFID Access Cards
RFID access cards exchange data using radio waves.
RFID includes LF, HF, and UHF cards. All of them have chips and antennas.
This technology is available in cards, key fobs, bracelets, stickers, and tags.
RFID security depends on the chips, keys, readers, and system configuration.
Smart Access Cards
A smart card can store information and perform some data processing.
Smart cards typically operate at a frequency of 13.56 MHz and can write information, encrypt data, and authenticate users.
An ordinary card might only communicate its ID. But, a smart card can validate a secret key.
MIFARE Access Cards
MIFARE is a contactless chip family from NXP.
Options include Ultralight, Classic, Plus, and DESFire.
Classic remains common but has known security limits. Plus supports stronger protection.
DESFire suits secure multi-use systems. A campus may use one card for doors, meals, and libraries.
NFC Access Cards
NFC access cards operate at 13.56 MHz over short ranges.
Some cards work with compatible mobile phones. However, not all NFC cards necessarily work with phones.
The devices need to comply with the same standards.
HID Access Cards
HID is a company name, not a card type.
Its card families include Prox, iCLASS, iCLASS SE, and Seos. These vary in frequency, format, and security.
When ordering, check the card family, facility code, serial number, and encoding.
UHF Access Cards
UHF access cards normally operate at frequencies between 860 and 960 MHz.
This provides a longer range and is suitable for parking areas and vehicle gate entry.
Metallic objects, water, tag orientation, and reader positioning can affect their performance.
Key Fobs, Wristbands and RFID Tags
Many access cards are available in key fob, wristband, label, and token forms.
Key fobs are commonly used in flats and gyms. Wristbands are commonly used in pools, resorts, and hospitals.
The shape determines the usage. The chip determines compatibility.

Access Control Cards by RFID Frequency

125kHz LF Access Cards
125kHz LF access card frequency provides basic identification. Common types include EM4100, TK4100, T5577, and HID Prox. They offer low-cost performance and short-range reading. They are widely used in many older buildings. Most low-frequency cards have limited encryption.
13.56MHz HF Access Cards
13.56MHz HF access card frequency offers greater data storage and stronger security. Common types include MIFARE, DESFire, NTAG, LEGIC, and iCLASS.They usually use ISO/IEC 14443 short-range contactless communication. However, reader compatibility can vary widely.
860-960MHz UHF Access Cards
860-960MHz UHF access cards offer a longer reading range. They’re ideal for vehicle, logistics, and parking gate applications. Performance depends on several factors, including the reader, antenna, tag placement, and local regulations. Test them on-site before placing an order.
Proximity Cards vs Smart Cards vs RFID Cards

RFID is the general term.
Both proximity cards and smart cards use RFID technology.
A proximity card typically transmits a single static identifier at 125 kHz. A smart card may store information and provide secure authentication at 13.56 MHz.
Think of RFID as the overall family.
Proximity cards and smart cards are two categories within the RFID family.
Access Control Cards by Application

Office Access Cards
Office cards can be used for door access, elevators, attendance tracking, and printer access.
A small office may use proximity cards. Secure sites may use DESFire or HID Seos cards.
Hotel Key Cards
Hotels may use magnetic stripe, MIFARE, or smart cards.
