I am looking for help with the connection of RFID readers in B4A

I only need an event with the card ID wenn one card is entering. The device is connected to USB. I am very reluctant to use the Keyboard Events, and if so, very reliably. The readers that are embedded in the keyboard ebvents do not provide a header and footer to recognize them.
I have various devices for testing here. ACR 122 as well. I've tried a lot, unfortunately without success. I want a really simple solution and I don't have that much experience with Android and B4A. If someone has experience that would be helpful. I am also ready to buy other RFID readers, if it's necessary.

Payment: hourly. Paypal possible
Language German, English
Working method: Skype, Zoom, Teamviewer

Ich benötige weitere Informationen darüber, was Sie tun möchten und wo der Reader installiert ist. Sie können mir auf Englisch schreiben. Ich habe ein Gespräch gesendet und werde viele Zweifel klären können.

I am replying to what I understood from your question:
Most RFID readers have a CRLF at the end of every successful transmission, so you can take that end code (the CRLF) and use it as TextReceived event. (A new event that I just made it up:)

Edit:
I am using this one without problem
