AES PROXCARD-125K-AES, AES Branded Prox Card - Single 125KHz fixed 10 digit code[price breaks at 10, 25, 50, 100, 500, 1000]
The AES PROXCARD-125K-AES is an AES-branded 125 kHz proximity card with a fixed 10-digit code. It is used as an access credential for compatible proximity card readers and AES access control systems that are designed to accept this type of 125 kHz card.
This listing is for one single prox card. It is a good choice when adding an individual user, replacing a lost or damaged credential, issuing a spare access card, or keeping replacement cards available for a managed entry system. Larger projects can use the available price-break quantities shown in the listing.
What This Prox Card Does
The PROXCARD-125K-AES allows an authorized user to present a 125 kHz proximity card to a compatible reader. Once the reader recognizes the card and the system is programmed to accept that credential number, the access control system can allow entry according to the permissions set by the installer, property manager, or system administrator.

Compatible With
The AES PROXCARD-125K-AES may be used with select AES and access control systems that support 125 kHz proximity credentials with the proper card format and programming method. Always verify the installed reader, credential format, card number handling, and access control software requirements before ordering cards in quantity.
- Select AES proximity access control systems that support 125 kHz credentials
- Select AES keypad, reader, and entry systems where 125 kHz prox card credentials are supported
- Select third-party access control readers that support the same 125 kHz credential type and format

- Replacement applications where the existing card is confirmed as AES PROXCARD-125K-AES or the system is confirmed to accept this card type
Important Compatibility Warning
Do not order 125 kHz prox cards by frequency alone. Many cards may be listed as 125 kHz, but the internal credential format, number structure, facility code, reader compatibility, and system programming method can differ. A card can be the correct frequency and still fail to read or enroll if the format is not supported by the reader or access control system.
- Confirm the required part number is PROXCARD-125K-AES.
- Confirm the system uses 125 kHz proximity cards.
- Confirm the fixed 10-digit code format is accepted by the installed reader and software.
- Confirm whether the system needs a card number only or also requires facility/site code information.
- Confirm the card can be enrolled into the installed AES or access control platform.
- Do not confuse this with 13.56 MHz MIFARE credentials.
- Do not confuse this card with a prox tag, key fob, reader, keypad, or access controller.
PROXCARD-125K-AES Compared With Similar AES Credentials
| Item | General Use | Important Difference |
| PROXCARD-125K-AES | AES-branded 125 kHz prox card | Single card with fixed 10-digit code |
| AES-PROX-TAG | AES-branded 125 kHz prox tag / fob-style credential | Different physical form factor; tag/fob instead of card |
| MIFARE-PROX-CARD | AES-branded MIFARE credential | 13.56 MHz credential; not the same as a 125 kHz prox card |
| Generic 125 kHz card | Low-frequency proximity credential | May use a different internal format and may not enroll or read correctly |
| Card reader | Device that reads credentials | Reader is separate hardware; this item is only the card credential |
Similar Parts That Are Not Automatically Interchangeable
- AES AES-PROX-TAG: Related AES 125 kHz credential, but it is a tag/fob-style credential instead of a card.
- AES MIFARE-PROX-CARD: Related AES credential, but it is a 13.56 MHz MIFARE-style credential and should not be treated as the same as this 125 kHz prox card.
- Generic 125 kHz prox cards: May look similar and share the same frequency, but the internal format may not match the reader or AES system.
- HID-style credentials: HID Prox and other credential formats are not automatically interchangeable with AES fixed-code 125 kHz cards.
- Reader modules and access controllers: These are the devices that read or manage credentials. They are not included with this single card.
Not Intended For
- 13.56 MHz MIFARE reader applications unless the system also supports this specific 125 kHz credential type
- Replacing AES-PROX-TAG fobs where a tag/fob form factor is required
- Replacing a card reader, keypad, control board, or access control panel
- Systems that require a specific HID, AWID, Keri, MIFARE, DESFire, or other credential format unless compatibility is confirmed
- Applications where the access control system requires custom facility code/card number programming that this fixed-code card does not provide
- Cloning or duplicating protected access credentials
- Bypassing building, gate, door, emergency access, fire access, or access control security procedures

Technician Note
The most important check is the reader and credential format. A card can be 125 kHz and still not work if the reader is expecting a different format, number structure, facility code, or credential technology. Before ordering a large quantity, test one card or confirm the exact credential requirement from the installed system.
If a card will not enroll or read, check the reader type, wiring, reader power, access control software, credential format, card number entry method, and whether the system requires a facility code. Do not assume the card is bad until the reader and system programming have been verified.
Before Ordering, Confirm
- Confirm the exact part number is PROXCARD-125K-AES.
- Confirm the system uses 125 kHz proximity credentials.
- Confirm the reader supports this AES fixed 10-digit code prox card.
- Confirm the access control system can enroll or accept the card number format.
- Confirm whether the system needs facility code, site code, card number range, or other credential details.
- Confirm whether a card format or tag/fob format is preferred for the users.
- Confirm this is not being ordered for a 13.56 MHz MIFARE reader.
- Confirm this is not being ordered to replace a reader, keypad, PCB, or access control panel.
- For larger orders, confirm compatibility before ordering price-break quantities.
Installation and Service Notes
- Enroll the card according to the access control system instructions.
- Record the card number and assigned user according to the property or site access policy.
- Test the card at the intended reader after enrollment.
- Verify the user has the correct door, gate, schedule, and permission group.
- Disable lost or stolen cards in the access control system before issuing replacements.
- Do not drill, cut, bend, heat, or modify the card.
- Keep card records organized when ordering large quantities.
- Do not use new credentials to bypass site security, emergency access, fire access, or gate safety procedures.
Professional Advisory
Access credential enrollment, reader compatibility, access permissions, and user management should be handled by a qualified access control technician, property manager, or authorized system administrator. Do not issue, clone, share, or program credentials in a way that bypasses building security, gate access policy, emergency access equipment, fire access equipment, monitored gate safety devices, or operator safety circuits.
Product Questions & Answers
What is the AES PROXCARD-125K-AES?
The AES PROXCARD-125K-AES is an AES-branded 125 kHz proximity access card with a fixed 10-digit code. It is used as a credential for compatible proximity readers and access control systems.
Is this listing for one card?
Yes. This listing is for a single AES PROXCARD-125K-AES card. The supplied product title also notes price breaks at 10, 25, 50, 100, 500, and 1000 cards for larger orders.
Will this card work with every 125 kHz reader?
No. Frequency alone does not guarantee compatibility. The reader and access control system must support the card format, number structure, and enrollment method used by this AES 125 kHz fixed-code card.
No. AES-PROX-TAG is a tag or fob-style credential. PROXCARD-125K-AES is a card-style credential. Both may be related 125 kHz AES credential products, but they are different form factors.
Is this the same as a MIFARE card?
No. This is a 125 kHz proximity card. MIFARE credentials commonly operate at 13.56 MHz and should not be treated as interchangeable unless the reader and system specifically support both credential types.
Does the card need to be programmed into the access system?
Yes. In most access control systems, the card must be enrolled, assigned to a user, and given the correct access permissions before it will open a gate, door, or controlled entry point.
What should be checked before ordering a large quantity?
Before ordering a large quantity, confirm the installed reader type, credential frequency, card format, 10-digit code handling, facility or site code requirements if any, and the access control software enrollment process.
