Razumevanje razlik med oznakama RFID 13,56 MHz in 125 kHz
Choosing between 13.56 MHz and 125 kHz RFID tags isn't just about specs—it's about finding the right fit for your environment, security needs, and future goals. This guide breaks it all down without hype, helping you make a smart, informed decision.
What RFID Frequency Really Means (LF vs HF)
RFID systems use radio waves to communicate between oznake and readers. The frequency they use affects how far they can read, how fast they send data, how they behave around metal or water, and what kind of data they can store.
Here’s the core idea:
Low-Frequency (LF) = 125 kHz RFID Tags
- Short range
- Slower data rate
- Excellent performance near metal or liquids
- Simple, rugged, and affordable
High-Frequency (HF) = 13,56 MHz oznake RFID - Daljši doseg
- Faster data rate
- More advanced security
- Compatible with NFC and smartphones
13.56 MHz vs. 125 kHz
| Funkcija | 13,56 MHz oznake RFID | 125 kHz oznake RFID |
|---|---|---|
| Pogostost | 13,56 MHz (HF) | 125 kHz (LF) |
| Preberi obseg | Do 1 metra | 2-10 cm |
| Hitrost prenosa podatkov | visoko | Nizka |
| Performance Near Metal | Zmerno | Močna |
| Varnost | Supports encryption, mutual authentication | Basic, usually no encryption |
| NFC / Smartphone Support | ja | št |
| Stroški | višje | Nižje |
Security: Is One Frequency Safer?
125 kHz oznake RFID are often used in older systems and typically use fixed unique IDs with no encryption. That makes them easy to clone with off-the-shelf devices. They’re okay for low-risk systems, but they don’t meet modern security standards.
13.56 MHz RFID Tags, especially MIFARE or DESFire cards, support:
- Šifriranje
- Mutual authentication
- Secure memory storage
- Multiple applications on a single card
Bottom line: - Stick with 125 kHz RFID Tags for low-security needs (like locker keys, time clocks).
- Choose 13.56 MHz for access control, payments, or any system storing personal data.
NFC and Smartphone Compatibility
If your project involves phones, 125 kHz RFID Tags won’t work.
Only 13,56 MHz oznake RFID support NFC (Near Field Communication)—the tech used in mobile payments, check-ins, and tap-to-pair features.
Most smartphones can read and write NFC tags using 13.56 MHz, making this frequency ideal for:
- Digital tickets
- Event check-ins
- Pametni plakati
- Loyalty cards
- Contactless mobile ID
If smartphone support matters, 13.56 MHz is your only choice.
Real-World Use Cases by Industry
| Industry / Application | 125 kHz oznake RFID | 13,56 MHz oznake RFID |
|---|---|---|
| Nadzor dostopa | Basic entry systems, legacy doors | Secure credentials, modern ID badges |
| Public Transport / Ticketing | Not supported | MIFARE/NFC-based fare cards |
| Sledenje živalim | Widely used due to tissue penetration | Rare |
| Industrijska avtomatizacija | Reliable near metal/liquid, rugged use | Less common in harsh environments |
| Zdravstveno varstvo | Not ideal for patient or medication tracking | Better for secure ID and asset tagging |
| Libraries / Archives | Rare | Popular for book tracking and checkouts |
| Marketing / Events | Not applicable | Smart posters, NFC event passes |
| Vehicle Anti-Theft | Embedded 125 kHz RFID Tags in keys/ignitions | Not used |
How to Choose Between 13.56 MHz and 125 kHz for Your Project
Use this checklist to narrow down your decision:
1. Security Level
- Need encryption or secure access? → Go with 13.56 MHz
- Low-risk tracking or basic ID? → 125 kHz may be enough.
2. Environment
- High interference, metal, or liquid nearby? → 125 kHz works better
- Clean office or indoor space? → Either works; choose based on features.
3. Smartphone Integration
- Want users to scan with phones? → Only 13.56 MHz supports this
4. Budget
- 125 kHz tags are cheaper upfront
- But 13.56 MHz offers more long-term value if you need features or security.
Still Using 125 kHz RFID Tags? Upgrade or Stay?
125 kHz RFID Tags are still widely used in:
- Legacy access control systems
- Factory floor operations
- Livestock tagging
- Auto anti-theft systems
But if you’re managing: - Staff credentials
- Plačilni sistemi
- Multi-use ID cards
- NFC integration
…then it might be time to switch.
Upgrade Paths:
- Install dual-frequency readers
- Issue combo cards (support both 13.56 MHz and 125 kHz)
- Gradual rollout: support both systems during migration
FAQs About 13.56 MHz vs 125 kHz RFID
Is 13.56 MHz the same as NFC?
Yes, NFC is a type of 13.56 MHz RFID. Most smartphones support it.
Can one reader read both frequencies?
Not usually. You’ll need a dual-technology reader to handle both.
Which tag has longer range?
13.56 MHz generally has a longer read range (up to 1 meter). 125 kHz is limited to a few centimeters.
Which should I use for access control?
For modern, secure access systems, 13.56 MHz is strongly recommended.
Zakaj imajo oznake RFID 13,56 MHz in 125 kHz različne razdalje branja?
Razlika v razdaljah branja je predvsem posledica frekvence delovanja. Višje frekvence, kot je 13,56 MHz, imajo večji obseg, medtem ko so nižje frekvence, kot je 125 kHz, optimizirane za krajše razdalje.
Katera oznaka RFID je bolj primerna za kovinska ali tekoča okolja?
Oznake RFID 125 kHz so bolj učinkovite v okoljih s kovinami ali tekočinami zaradi svojih boljših sposobnosti prodiranja.
Ali cena oznak RFID vpliva na izbiro?
Da, oznake RFID s frekvenco 125 kHz so na splošno stroškovno učinkovitejše, zaradi česar so primerna možnost za proračunske aplikacije. Vendar je treba pri izbiri upoštevati tudi zahteve glede zmogljivosti in aplikacijska okolja.
Key Standards and Chip Types
13,56 MHz (HF)
- ISO/IEC 14443: Used in contactless cards (MIFARE, DESFire)
- ISO/IEC 15693: Longer range, used in libraries, logistics
- ISO 18000-3: Item-level tracking
125 kHz (LF)
- Proprietary formats, often fixed-ID (e.g., EM4100, HID Prox)
- Mostly used in older systems and basic applications
Final Takeaways
If you’re still wondering which way to go, here’s the summary:
Use 125 kHz RFID Tags for:
- Harsh conditions (metal/liquid)
- Low-security applications
- Budget-conscious deployments
- Legacy systems
Use 13.56 MHz RFID Tags for:
- Mobile/NFC support
- Secure access and payment
- Multi-use cards
- Future-ready systems
Both have a place—but you should pick based on use case, not just cost or habit.

Tehnologija RFID (radiofrekvenčna identifikacija) je povsod: na kreditnih karticah, osebnih izkaznicah, vozovnicah, ključih hotelskih sob in drugje. Omogoča hitrost in udobje, vendar odpira tudi vrata novi vrsti digitalne kraje, imenovani "skimming". Tu pride prav zaščita za kartice RFID.
Zapestnice RFID za dogodke: Priročnik za množično nakupovanje za organizatorje
Zapestnice RFID za prireditve postajajo rešitev za organizatorje, ki na koncertih, festivalih in športnih prizoriščih potrebujejo hitrejši vstop, preprečevanje goljufij in brezgotovinsko plačevanje. Za razliko od papirnatih vstopnic ali kod QR te pametne zapestnice uporabljajo vgrajene čipe za poenostavitev dostopa, zavarovanje transakcij in izboljšanje izkušnje gostov.
Kako oznaka RFID na vetrobranskem steklu izboljša nadzor dostopa vozil in sisteme cestninjenja
V današnjem hitrem svetu mora biti identifikacija vozila hitra, varna in brezstična. Oznaka RFID na vetrobranskem steklu zagotavlja prav to - zanesljiv način upravljanja cestninjenja, parkiranja in zaprtega dostopa brez ustavljanja vozil.
Prednosti oznak RFID za perilo v poslovnih pralnicah
Vodenje pralnic v bolnišnicah, hotelih ali velikih pralnicah je veliko delo. Vsak dan je treba oprati, razvrstiti in poslati nazaj na tisoče rjuh, brisač in uniform. Toda težave, kot so izgubljeno perilo, napake pri razvrščanju in ročno štetje, lahko podjetja stanejo veliko denarja. Na primer, srednje veliki hoteli lahko vsako leto izgubijo več kot $200.000 zaradi manjkajoče posteljnine.
Tu pridejo na vrsto oznake RFID za perilo.
