RFID wristbands vs QR code wristbands, which is better? This question can be confusing to event organizers as they try to balance management efficiency and event profitability.
The truth is, both technologies have distinct benefits and shortcomings. In this guide, we break down everything you need to know to make the right call for your event.
RFID Wristbands vs QR Code Wristbands: What are the Differences?
While RFID and QR are both used to transmit data wirelessly, they work significantly differently. Here are the major differences:
1. Mechanism of Action
An RFID wristband has a small RFID chip that stores data, an antenna that transmits radio waves, and a substrate for protection. The chip is encoded with data that is specific to a given guest.
Once that guest wears it and approaches a reader, the chip will be activated by the reader’s RF waves, creating an electromagnetic field that facilitates data transmission. In this case, there is no need for a line of sight, and the whole process takes less than a second!
On the other hand, a QR wristband has a printed code on its surface. To scan it, a reader (sometimes a smartphone) needs a clear line of sight.
The guest must hold their wrist at the right angle to ensure a clean and unobstructed line of sight. This is a major disadvantage of QR codes of wristbands, especially when used for large-scale events since it takes a lot of time to scan a single wristband!
2. Speed, Safety, and Reliability: Head-to-Head Comparison
When it comes to speed, RFID wristbands win hands down. The time taken by an RFID scanner to register a swipe from the wristband is less than two seconds. QR code scanning takes longer since it needs the code to be aligned and focused, especially when there is a dirty surface.
Another area where the two technologies sharply differ is security.
A QR code placed on a wristband can be photographed, captured via screenshot, and even sent to another person. Thus, if a participant takes a picture of their own code and then forwards it to another party, both users will be able to access a venue with this QR code. This cannot happen with RFID chips since each chip comes with a unique encrypted identifier which cannot be duplicated or forwarded by any means.
On matters of reliability, QR codes are not as reliable as RFID wristbands. A QR wristband gets dirty, wet, and damaged over the course of several days during the event. If the QR code becomes too worn out or gets soaked with water, it cannot be scanned anymore. On the contrary, RFID chips are protected since they are inside a wristband, thus remaining functional no matter what happens to its exterior surface.
Despite their many shortcomings, QR wristbands have some strengths too. For example, they are more affordable than RFID ones; they are also easy to read through a smartphone camera, and they don’t need additional scanners.
3. Cost Differences Between RFID and QR Code Systems
QR code wristbands are much cheaper than RFID wristbands (price per unit). If you have only one day to host an event and don’t require much sophistication, the pricing might be sufficient grounds to go with QR code wristbands.
On the other hand, RFID wristbands come at a higher cost due to the relatively pricey chip and additional infrastructure requirements. Besides purchasing readers, installing the data computer system and establishing the cashless payments support system will require huge upfront investment.
Still, when you look at all the factors, RFID wristbands will provide better value. They guarantee an increase in expenditure, especially during events and concerts, due to the easy payment procedure. Also, you can be sure of faster check-in, improved flow of guests, and an overall better experience when using RFID as opposed to the QR codes.
Which Technology Suits Your Event Best
The answer will depend on what requirements you have for your wristband.
Use QR code wristbands in case you have a smaller-scale event, are working on a tight budget, do not need complex access control, and do not intend to implement a cashless payment system. A neighborhood event, mini-conference, and an outdoor market operating for a day can work perfectly well with QR code wristbands.
RFID wristbands should be used for events requiring cashless payments, multi-level access control, fast processing of large crowds of people, and in general in cases when security and speed cannot be compromised. Music festivals, sports events, company-wide conferences, and other kinds of multi-day activities will work best with this technology.
It should also be noted that the user experience matters. The RFID wristband solution operates seamlessly. Guests simply scan and go, without any delay. The scanning of QR codes, though efficient, still involves some close interaction with the reader, which may cause issues when trying to get through an access point quickly.
When it comes to protection against forgery and the security of the event itself, RFID technology remains the only reasonable solution available. Most of the data stored in the chips is encrypted and can only be accessed via the central computer system.
Conclusion
RFID wristbands vs QR code wristbands is ultimately a question of what your event demands. QR codes are affordable, accessible, and sufficient for simple use cases. They are your go-to option when you have a small, single-day event. However, you will have to sacrifice speed and convenience since this option requires a direct line of sight, leading to delays.
On the other hand, RFID wristbands are significantly faster, safer, and more advanced when compared to other types of wristbands because they can be used to deal with financial transactions and large crowds. This, though, comes at a price. This pick is costlier and requires more capital to set up the required infrastructure.
To find out which wristband system suits your event, the first step to take is to look at the entrance. How many visitors will arrive each hour? Will there be cashless transactions involved? Is there going to be specialized scanning equipment? The answer to these questions will show you the way.
