Hotels use wristbands for various reasons, primarily for guest identification and access control. Here are a few reasons why hotels use wristbands:

Identification: Wristbands help hotel staff quickly identify guests who are entitled to use certain amenities or services, such as access to the pool, gym, or all-inclusive privileges at resorts.

Security: Wristbands can serve as a security measure to prevent unauthorized access to hotel facilities or events. They can also help prevent non-guests from entering restricted areas.

Convenience: Wristbands are more convenient for guests than traditional keycards or physical tickets. They are worn on the wrist, allowing guests to access amenities without worrying about carrying keys or tickets.

Branding: Some hotels use custom-designed wristbands as a branding opportunity. These wristbands may feature the hotel's logo or colors, helping to reinforce the hotel's brand image.

Tracking: In some cases, hotels may use wristbands with RFID or NFC technology to track guest activity or purchases within the hotel premises. This can provide valuable data for marketing purposes or to improve guest experiences.

Overall, wristbands offer a practical solution for guest identification, security, and convenience, making them a common feature in many hotels, especially resorts and large properties with multiple amenities.
